"With this membrane, the leaching and extraction of lithium battery recycling can be directly combined into one."

"In this way, it seems that there is no need for too much space, just build an integrated recycling equipment."

"Throw the battery here, and spit out the metal elements of all kinds of batteries over there."

"In the future, it will be further miniaturized, and it can also be installed in drones, oceans, moons and other places for casual mining."

With this metamorphosis biofilm.

Chen Yi quickly decided not to engage in large-scale chemical equipment, but to directly build an integrated lithium battery recycling equipment.

"Before determining the design of the equipment, it is necessary to determine the adsorption efficiency and adsorption capacity of the biofilm."

"Also, the most important point is to adjust and improve the biofilm that absorbs all metals into a biofilm that absorbs elemental metals."

Chen Yi looked at the attribute interface of the biofilm in front of him.

To put it bluntly.

This biofilm has gone crazy enough to wipe out the entire metallic element of the periodic table.

It is not an exaggeration to call it a metal gluttonous film.

According to the evaluation of the system's remarks.

Through the conductivity of different metals, the absorption rate is different, and the metal can be classified and adsorbed.

But after a few virtual chemistry teachers taught by word and deed.

Chen Yi understands very well that even if the absorption rate is different, there will still be a little other substance involved in the reaction when most of the reaction is carried out.

This little thing that reacts with it.

If it is not purified, this will affect the material of the material.

Choosing to purify, the cost has gone up again.

We need to address the root cause of this problem.

Chen Yi only adjusted and improved this all-metal all-metal biofilm into a single metal elemental film

For example, lithium is needed, and this takes out the biofilm of lithium.

If uranium is needed, then come up with a biofilm against uranium.

According to this line of thought and direction.

Chen Yi prepared a cup of solution rich in various gold elements in the laboratory.

Take a piece of biofilm that has been cut out, simply measure the area, and start the experiment.

"21.3 square centimeters, in units of 5 seconds."

Put the biofilm on the test bench, the instrument will automatically pour the solution, and the test bench will start to rotate at the same time to maximize the contact between the biofilm and the solution.

After 5 seconds, the solution is drained.

Chen Yi looked at the translucent yellowish biofilm that turned black, dried the moisture on the surface, and then measured the weight.

7.81 grams more.

"That's a bit amazing."

Chen Yi was a little surprised.

This 7.81 grams is undoubtedly the metal element adsorbed by this biofilm in 5 seconds.

You know, it's just a 21.3 square centimeter piece of biofilm.

If the biofilm is rolled up and the contact area per unit time is increased, the adsorption efficiency will be exponentially increased.

"One more time."

Pour the solution a second time.

Rotate again to increase contact and drain after 5 seconds.

Chen Yi dries the biofilm and measures the weight.

15.63 grams more.

Minus the first 7.81 grams.

The weight of this adsorption is 0.01 more.

The third time. The weight increased by 7.8 grams, and the adsorption efficiency was still stable.

The fourth time, it was still 7.81 grams, and the adsorption was still stable.

The fifth time, with an increase of 6.27 grams, the adsorption efficiency decreased by a little more than 20 percent.

The sixth time, 5.03 grams were added, reaching the adsorption limit of the biofilm.

"The adsorption efficiency is 73 milligrams per second, and the total adsorption capacity reaches 2 grams."

"The efficiency of this biofilm is a little scary."

Chen Yi looked at the weight of 42.6 grams added up to the six times, and there was a hint of shock in his eyes.

This is no longer metal adsorption, this can be regarded as metal eating.

Be aware that the biofilm before adsorption.

With a weight of 21.3 square centimeters, this is only a little more than 6 grams.

After adsorbing metal elements, its weight has increased by more than 8 times, and the absorbent paper is not so excessive.

"As for extracting the adsorbed metals, it's easy."

Chen Yi wore rubber gloves and picked up the crucible that weighed almost 50 grams of biofilm and threw it aside.

After some heating.

Biofilm dissolves and vaporizes.

Only a small cloud of black powder rich in various metallic elements remained in the crucible.

Chen Yi simply replaced and restored this powder, got it out and put it on the electronic scale, and got the accurate weight.

"42.56 grams, it looks like some is missing."

After recording all the data, Chen Yi began to adjust the properties of the biofilm.

Colorful light blooms.

Envelop the remaining small piece of biofilm.

Wait for the light to dissipate.

The biofilm in front of me changes color.

From yellowish to transparent, to silvery-white translucent.

[Item: Metallophilic Bioadsorption Membrane]

[Attributes: Strength x29.2, Alkali Metal x109.2, Alkaline Earth Metal x29.5, Transition Metal x25.1, Main Group Metal x28.4]

[If you detect that a property exceeds the initial value, do you want to read the information?] Yes/No! 】

[Note: This is a biofilm with insane alkali metal affinity and strong adsorption capacity for other metal elements.]

In front of it, not a single alkali metal ion can escape the fate of adsorption.

At the same time, it is not expensive in strength and can withstand huge pressure without breaking.

With the help of pressure and alkali metal affinity, it is easy to crush and split all alkali metal compounds. 】

"Read!"

Chen Yi did not hesitate and chose to read the information.

Suddenly, a special biofilm structure and basic principle, as well as the corresponding chemical production method, biological production method, emerged in my mind.

With the assistance of the system, Chen Yi quickly digested this technical information.

Then through the brainwave sensing headband, the production method and technology are uploaded to the supercomputer.

"Xuannu, make an alkali metal adsorption film and send it over."

"Your order received."

Xuannu responded.

Soon, less than thirty minutes.

A small piece of biofilm with a small fingernail was made and delivered.

Chen Yi manually divided the biofilm into two halves, and the attribute interface popped up.

[Item: Alkali metal - bioadsorbent membrane]

[Attributes: Strength x29.2, Lithium x86, Potassium x86, Rubidium x86, Cesium x86, Francium x86]

[Note: This is a biofilm with insane alkali metal affinity. 】

"It's simply the nemesis of alkali metals."

"But at the moment, I just need lithium."

Chen Yi didn't hesitate and quickly adjusted his attributes.

[Lithium: 86→139]

[If you detect that a property exceeds the initial value, do you want to read the information?] Yes/No! 】

Soon, the properties of lithium changed from 86 to 139, reaching the limit of artificial semi-permeable membranes.

Reading the information, Chen Yi sent the relevant technical information to the Xuannu as usual.

Next, Chen Yi followed the same method.

The "hyper-elemental bioadsorbent membrane" was prepared separately.

Raise the adsorption attribute of the cobalt element to the maximum, read the technical information, and send it to the Xuannu.

There are also bioadsorption films of metal elements contained in lithium batteries such as manganese and nickel, which are read together and sent to Xuannu.

"The adsorption and extraction of biofilms of various elements is completed, and the next step is the integrated equipment for lithium battery recycling."

"Discharge, crushing, leaching, extraction and other links are fine, but this discharge link is a bit difficult for the equipment."

Chen Yi frowned, the discharge step before the lithium battery was crushed.

At present, liquid nitrogen is either used to freeze to a very low temperature, punctured and short-circuited forcibly discharged, or chemical discharge with electrolyte.

"If you want to make an integrated equipment, you have to solve the problem of this discharge link, otherwise the equipment will be easily scrapped."

"I just read the literature, it seems that there is an eagle sauce, oh, it's Ma Da Li-Cycle company."

"A mechanical method is adopted to reduce the size of the battery without discharging, and then the electrode material of the battery is leached by hydrometallurgy."

"Mechanically reduce the size of the battery. How does this feel a bit like the hydraulic law of a hydraulic press? ”

A stalk of a hydraulic press popped up in Chen Yi's mind.

Ever since there was a hydraulic press at home, only a hydraulic press was left at home.

"Isn't it, just try it."

"If you can't do it, you can take a virtual learning opportunity, or skip the discharge link and use the discharged battery for shredding and recycling."

"It's just that it needs an upstream enterprise in the industrial chain, and it is also a chemical electrolysis enterprise with great pollution. If you can, you won't do it. ”

Chen Yi found a few lithium batteries that had run out of electricity on the surface, but there was still residual power inside.

Use the machine tool to simply cut a piece of the platform that is concave to help reduce the size of the battery, and then take the battery and platform to the hydraulic machine at the base.

Place the platform and battery, and adjust the angle.

Chen Yi turned on the switch of the hydraulic press.

Bang dang!

The heavy metal pile began to sink, aiming at the battery and pressing hard against it last time.

Crunch!

But two seconds.

Lots of smoke and an unpleasant smell, as well as a subtle glow of fire.

Rises from the edge of the gap in the platform.

Base smoke induction activation.

The exhaust fan around it rotates, sucking the smoke and smell away.

Wait for the short circuit reaction of the battery to end.

Chen Yi put on a mask, took the infrared temperature controller, raised the hydraulic press to check it, and came to several conclusions.

"The size of the volume has been reduced."

"The battery underwent a short-circuit reaction due to extrusion, and thermal runaway occurred, and the temperature soared to seven or eight hundred degrees Celsius in an instant."

"The high temperature and the short circuit, which triggered a violent reaction, caused the battery to burn, but it did not explode."

"In this way, if there is a special leaching solution, in addition to leaching out the electrode material of the battery."

"It can also improve the difficulty of battery reaction combustion, and at the same time can cool the battery, and can also adsorb the toxic gases produced by the battery reaction."

"Soaking the battery in such an leaching solution and squeezing and crushing it can save all problems?"

Chen Yi's brain opened and he quickly thought of a way to solve the problem of battery short-circuit discharge.

After all, lithium batteries are used up and then recycled.

Even if there is still some unused power left inside, this little power can't turn over too much wind and waves.

In this way, it is highly feasible to cool down by wet process and at the same time increase the difficulty of the battery combustion reaction.

Combustion is suppressed.

The so-called battery explosion will naturally not appear.

Just do it when you think of it.

Chen Yi passed on his thoughts to the Xuannu.

For the study of chemistry and biology.

Now the Xuannu who nests in the laboratory every day is the main beam.

Airplanes!

The supercomputer outside buzzed for a while.

More than ten minutes passed.

The four chemical formulas were passed back by the Xuannu.

It means that these four chemical formulas are suitable for the common ternary lithium, lithium iron phosphate, lithium cobalt oxide, and lithium carbosilicon of Yifei.

Follow the chemical formula as directed.

Chen Yi spent more than two hours carefully preparing the three solutions of ternary lithium, lithium iron phosphate and lithium cobalt oxide, and started the piling test of the hydraulic press again.

A special sprinkler platform was designed.

A special leaching solution is poured into it, which submerges the battery in it and at the same time passes through the circulation system, which continuously circulates and sprays.

Chen Yi first applied a solution of lithium cobalt oxide.

Bang dang!

The pile head of the hydraulic press sinks and starts to drive the pile.

A few seconds later.

The heavy pile head sinks to the lithium cobalt oxide battery immersed in the solution.

The sprinkler system then turned on and sprayed the solution continuously onto the battery and pile headband.

Goo, goo.

The hydraulic press drives the pile to the end.

Two bubbles bubbled up in the solution.

Imaginary smoke, sparks, burning explosions, nothing happens.

Only the originally clear solution began to turn black and cloudy.

There seems to be a large amount of battery material that has been leached and melted into it.

"Perfect, sure enough, the wet method must be chosen for mechanical piling extrusion."

"Dry piling extrusion, the risk is too high, and it is easy to get injured."

It was determined that there was no problem with wet piling, extrusion and crushing.

Chen Yi went through many trials and improvements, and it took five days.

Finally, a prototype of an integrated lithium battery recycling equipment was designed.

It's a bit like a roll-extruded, large-scale peanut oil press.

An inlet, followed by two high-torque, squeezing drums that roll against each other.

The battery was squeezed by a steel drum and the structure was destroyed.

This is followed by repeated grinding to ensure that the battery is crushed to the smallest particles.

After crushing the battery powder, this is sent to the leaching area at the back.

After a certain period of solution leaching, the valuable electrode materials contained in the battery powder will be leached, and then adsorbed and extracted through the biofilm.

Besides

The equipment is also designed with a circulating system for wet inhibition.

Through the pipeline, the filtered leachate is extracted and transported to the drum extrusion zone.

Suppresses reactive combustion caused by battery squeezing short circuits, and cools down at the same time.

Ensure that the grinding and crushing process from the drum extrusion to the back is carried out in a humid environment without reaction hazards.

The only consumable for the whole set of equipment is the leaching solution.

However, because the leached electrode material will be continuously adsorbed and extracted by the biofilm, the only leaching solution consumed can also be recycled in the equipment.

According to Chen Yi's calculations.

The leaching solution can be cycled 700 to 800 times overall, after which the leaching performance will be greatly reduced.

From 99.9 percent leaching, it dropped to 90 percent, 80 percent.

According to the standard of replacing when performance is degraded.

With an average of 1 kg of leaching solution, more than 1.3 kg of lithium can be leached.

In addition to silicon carbon cells, different battery types can handle batteries from 100 to 280 kg.

Calculated based on 50 kg of leaching solution for one device.

This equipment can process more than 10 tons of power batteries, which greatly improves the utilization efficiency of leaching solution and reduces the difficulty of pollution treatment.

"The last biofilm is still missing."

A prototype is produced with a machine tool and a printer.

Chen Yi took a roll and spent several hours, and Xuannu produced the lithium metal bioadsorption film and reduced a part of it.

[Item: Lithium - Biological Absolute Adsorption Membrane]

[Attributes: Strength x29.2, Lithium x139]

[Note: This is an absolutely affinity with lithium metal, making people crazy to adsorb any liquid lithium element and isotope, and none of them can escape its adsorption.] 】

"Absolute adsorption. This is simply the best equipment for doomsday masturbation technology. ”

Chen Yi took out a shell with a water inlet and outlet like a water purifier filter, rolled the adsorption membrane into a roll and stuffed it in, and then installed it tightly.

Test to make sure the inlet and outlet water is normal.

Chen Yi stuffed it into the lithium battery recycling equipment, one of the several adsorption extraction ports reserved.

Then I took the bioadsorption film of cobalt metal, and also minus a part.

[Item: Cobalt Elemental - Biological Absolute Adsorption Membrane]

[Attributes: Strength x29.2, Cobalt x139]

[Note: This is an absolute affinity for cobalt metal. 】

"With this cobalt bioadsorption membrane, the so-called cobalt bomb deterrence on the opposite side seems, as if, it is bankrupt and scrapped again."

Look at the equally perverted properties of this cobalt adsorption film.

Chen Yi was stunned for a moment, and suddenly remembered a funny thing in his heart.

With this, even if the opposite side shoots cobalt bullets like crazy.

It is only necessary to make some of these cobalt bioadsorption membranes in the water source area and living area.

After adsorption for a period of time, it is recycled and destroyed.

The radiation threat of this cobalt bomb is self-defeating.

"If you have time, I'll make an experiment video and send it to the other side."

Chen Yi smiled and stuffed the cobalt biofilm into the other extraction ports of the equipment, and then the adsorption membrane of nickel, manganese and other elements.

All adsorption membranes are installed.

An interface emerges before your eyes.

[Item: Perfect Level - Automatic Lithium Battery Recycling Equipment]

[Attributes: Strength x29.2, Lithium x139, Cobalt x139, Nickel x139, Manganese x139]

[Note: This is a perfect lithium battery recycling equipment beyond the imagination of the world, and no element of a lithium battery can withstand its recycling deprivation.

As a perfect-level device, a random core accessory in it can bring hundreds of millions of shocks to the world when taken out.

PS: Work hard to code words, readers, ask for a monthly pass.
