In 1799, the Italian physicist Volt immersed a zinc plate and a tin plate in salt water and discovered that there was an electric current passing through the wire connecting the two metals. So he put a lot of zinc and silver sheets between them with a flannel cloth or paper soaked in salt water, and folded them flat. When you touch both ends with your hands, you will feel a strong electrical stimulation. Voltaic succeeded in making the world's first battery, the "Volt Stack", using this method.

Therefore, the battery has a history of more than 200 years from its inception to the present.

However, more than 200 years have passed, and the energy density of the battery has not been significantly improved.

The earliest widely used battery is the carbon-zinc battery, which has an energy density of about 30-100h/kg, and is characterized by a one-time use, but low price.

The lead-acid battery invented subsequently is more widely used, with an energy density of about 80-120h/kg, but it can be repeatedly charged and discharged, and the price is cheap, and it has quickly become the mainstream, and has been popular for hundreds of years, and has not been eliminated until now.

However, the energy density of lead-acid batteries is too low, so in the sixties of the last century, lithium batteries came into being, with an energy density of up to 150-250h/kg, which is equivalent to twice that of lead-acid batteries.

Some high-performance lithium batteries can even reach an energy density of 300h/kg, and theoretically have the possibility of reaching an energy density of 1000h/kg.

But theories are just theories.

In reality, the energy density of lithium batteries is difficult to exceed 350h/kg.

It can only be regarded as a "semi-high-energy battery".

And due to the complexity of technology, safety, high production costs and other reasons, lithium batteries have not been promoted on a large scale until the 21st century, and have gradually become the mainstream.

In addition, there are many development paths for batteries, and several batteries with higher energy density, longer life and safer energy density in the future are being developed by institutions.

Such as metal-air batteries.

The representative of this type of battery is zinc-air battery. The specific energy of zinc-air batteries is 4~6 times that of lead-acid batteries, and 1 times greater than the specific energy of lithium-ion batteries, and the maximum range of electric vehicles powered by them can reach 400km.

The manufacturing process of zinc-air batteries is simple and low-cost. The cost of large quantities is about 300~500 yuan/kVAh, which is lower than that of lead-acid batteries. And safe and reliable, even if the outside encounters open flames, short circuits, punctures, impacts, etc., there will be no combustion and explosion.

But even with so many advantages, zinc-air batteries also have some fatal drawbacks, its use cost is relatively high, and the charging process is complex; The actual service life is short, 1~2 years, which is mainly not because of the poor electrochemical performance of the battery, but the influence of the structure of the battery; The mass production processing technology is not mature enough. This is mainly the manufacture of catalytic membranes and waterproof and breathable membranes, most of which require semi-mechanical operation, and there are some manual factors that lead to differences in electrode performance.

The promotion of all metal-air batteries is still relatively difficult.

In addition, there are all-solid-state batteries, nanocrystalline lithium-ion batteries, fuel cells, ...... And so on at least dozens of kinds of batteries.

Their energy density, some announced to reach 500h/kg, some announced to exceed 800, and some exceeded 1000, which can be described as exciting, as if seeing the hope of the arrival of the era of high-energy batteries.

But...... And then the eggs.

Laboratory performance is not the same as actual performance.

The products in the laboratory do not necessarily become market products.

In the current market, the ternary battery with the highest energy density is a ternary battery with a ternary polymer material (Li(NiCoMn)O2) combined with nickel-cobalt-lithium manganese oxide as the cathode.

In this type of battery, a domestic manufacturer combined graphene technology to achieve the world's highest energy density of 550h/kg, which caused a sensation in the world at that time, and was considered to be the coming of the new energy era.

But this joy may be premature.

Because the energy density of gasoline is as high as 12000h/kg, the energy density of the best ternary battery is only 4.58% of gasoline, less than one-twentieth.

Ternary battery technology has not yet come to replace traditional energy sources.

I just saw a glimmer of hope.

The successful development of Xinghai Technology's "high-energy No. 1" battery directly realizes this hope.

Inside the research center.

Therefore, Zhao Qiang, who was in charge of the project, said excitedly: "Mr. Chen, in terms of battery technology, we have achieved an amazing leapfrog breakthrough!" ”

"First of all, our 'High Energy No. 1' is not a traditional liquid or semi-solid-state battery, but an all-solid-state battery!"

"All-solid-state batteries have the highest safety, shock resistance, high temperature resistance, good stability, and more recharge times than other types of batteries."

"For example, the best quality ternary battery, its charging life is 1500 times, and after about 800 charges, the battery capacity drops to 80%; However, the number of charging times of 'Gaoneng 1' can reach 10,000 times, and the battery capacity will drop to about 80% after 5,000 charge-discharge cycles. ”

"And the 'high-energy No. 1' battery integrates the most advanced graphene fast charging technology, such as the 10,000 mAh mobile phone battery in my hand, which supports up to 100 watts of fast charging technology, and it only takes 6 to 10 minutes for this battery to be fully charged, and there is no need to worry about excessive heating."

Zhao Qiang took the small battery and continued: "As for its energy density, due to the use of a new nanopolymer material, as the positive electrode of the battery, its energy density has reached the level of 1500h/kg. ”

"That's six or seven times more than an ordinary lithium battery! Equivalent to one-eighth of gasoline. ”

"But in the actual use process, the energy utilization efficiency of the gasoline burned in the engine is at most 40%, and generally more than 30%."

"The utilization efficiency of batteries is generally more than 90%."

"Therefore, from the perspective of energy utilization efficiency, the actual efficiency of the 'high-energy No. 1' battery is equivalent to one-third of that of gasoline."

A third of gasoline!

That's pretty impressive.

The promotion potential of electric vehicles has instantly surpassed that of traditional fuel vehicles.

Because compared with the engine of a fuel vehicle, the electric motor of an electric vehicle has a simple structure and lighter weight, plus some attached mechanical structures, which saves hundreds of kilograms of mass.

Complex transmission structures such as gearboxes have been eliminated.

Overall weight loss of at least 200 kg.

Of course, in order to achieve the same range as fuel vehicles, the number of battery packs will definitely increase, and with the mass of 50 kg of gasoline in a tank, it must be equipped with a 150-kilogram "high-energy No. 1" battery to achieve the same range.

Even so!

The electric car equipped with the "High Energy No. 1" still loses more than 100 kilograms!

So the battery life will only be stronger.

And because of the state-of-the-art fast charging technology, it can fully charge a large volume of battery cells in half an hour to an hour, and the waiting process will not be particularly long.

As well as tens of thousands of times of charging life, extremely high safety......

At least in the automotive field, for the sake of environmental protection, ease of use, range, safety, cost and other comprehensive considerations.

With the advent of "Gaoneng 1", people can hardly find a reason to refuse electric vehicles.

Once this battery is on the market, it is conceivable that the sensational impact it will cause will be even more unimaginable; The global shocks in many fields are bound to cause huge pressure on Xinghai Technology.

So the question in front of Chen Jin is: should you detonate this bombshell?
