Chapter 252: Really! Microbial battery (kneel and beg!) )
The display displays: power 2.5W, real-time voltage: 4V, real-time current: 1.6A.
To see such data, to see a small light bulb that is on.
The lab fell silent.
Success comes too suddenly, happiness comes too suddenly.
This experiment proves the success of ionized bacteria in one fell swoop, and also proves that ionized bacteria can form small batteries under certain conditions.
What this experiment means!
It means that human beings will have a major breakthrough in the field of batteries, and it means that more convenient electrical appliances are about to appear.
There are many applications for bio-batteries that even laboratories cannot anticipate now.
Mo Li asked the members of the team to record this historic moment.
Zhou Xiao was relatively calm, and the experimental results were within his expectations.
The experiment continued as the team determined what the capacity of the biological battery would be under a standard special test tube.
There are two criteria for determining battery performance, one is voltage and the other is capacity.
Everyone looked at Zhou Xiao and waited for the boss to speak.
Zhou Xiao took a closer look at the big screen and said: "There are two problems that you should pay attention to, one is the stability of the battery, and the other is the application scenario." ”
"I also stayed up a few all-nighters and went to sleep, you guys study hard."
Zhou Xiao glanced at the system, and there was no change in the monopoly value and aversion value, but he firmly believed that this time the ionization bacteria would give the world a huge surprise, and even affect human industrial products.
Over the next few months, the laboratory conducted a detailed study of ionized bacteria.
The first is to thoroughly differentiate ionized bacteria and to culture and propagate them.
Fortunately, the growth environment of ionized bacteria is not particularly harsh, and they can survive at room temperature in nature, even if the temperature is relatively low, the heat emitted by ionized bacteria during metabolism can also keep the colony at a suitable temperature.
The second item is to test the capacitance of the ionized bacteria in a standard test tube without a light source at all and without decomposing any organic matter.
The final data is that in this extreme case, the capacitance of ionized bacteria in a standard test tube can reach 4000mAh.
This capacity is comparable to the battery capacity of many smart large-screen mobile phones now, and even higher than the battery capacity of Apple mobile phones.
The third item is to test how much electricity the ionized bacteria can have, and how much voltage it can provide in the case of special containers.
It is more energy-efficient to form a single bio-battery with a large container of a large number of ionized bacteria, or to use a small bio-cell to form a small bio-cell with a single piece of special test tubes.
The results are also quite encouraging.
With the same number of colonies, the two have about the same amount of electricity.
However, small bio-cells formed using small, specially made test tubes are more stable.
The voltage of a large number of ionized bacteria in large containers to form giant biological batteries is very unstable and is easily affected by temperature and local concentration of cultured bacteria.
The fourth experiment was the stability of ionized bacteria in different states.
This experiment is very important.
Because the colonies in the special test tube are still present in the culture medium, if it is fine in the case of fixation, the colonies are basically in a stable state in the solution.
However, if the tube is moving or jolting, the colonies in the solution will be jolted.
When the colony is bumpy, the potential difference in the special tube changes, and the voltage becomes unstable.
The voltage is unstable, and even if the biological battery has 4000mAh, it will not be able to use it in the case of unstable voltage.
Batteries are used much more in a mobile environment than when they are stable, so the unstable voltage is a great problem for the laboratory.
The fifth experiment was to test the survival state of ionized bacteria.
The so-called survival state is the survival and reproduction ability of ionized bacteria in the state of sufficient culture medium.
The test results found that the existing ionized bacteria can have a better survival rate and reproduction ability from minus 10 degrees to 60 degrees under the condition that the culture medium is sufficient, and the lifespan of ionized bacteria is about the same as that of digestive bacteria, about one month.
This test is closely related to the use case of ionized bacteria in the future.
The future application range of ionized bacteria will definitely not only be at home with constant temperature, but also from the north to the south, which may be cold in the northeast and hot in the south.
The strong adaptability of ionized bacteria ensures that it will be used in a wide range of environments in the future.
The sixth experiment is the ability of ionized bacteria to continuously supply electricity.
In the previous experiment, the ionization bacteria were tested under extreme conditions, and the level of ionized bacteria in the standard test tube was about 4000mAh.
But in fact, it is absolutely impossible for ionized bacteria to never see sunlight and never decompose organic matter.
As a progeny of Rhinobacterium, ionized bacteria are actually "relatives" of digestive bacteria, so ionized bacteria have the ability to correspond to Rhidax and digestive bacteria.
The first ability is that it can absorb sunlight for photosynthesis, and under the conditions of photosynthesis, ionized bacteria will replenish their own energy to continue to produce ionization, which is somewhat similar to solar cells.
But there is a question, what is the conversion rate of ionized bacteria to solar energy?
At present, most of the solar cells on the market are divided into two types, monocrystalline silicon and polycrystalline silicon.
The conversion rate of solar energy is about 10%-20%, which constitutes a solar panel, and the power is about 15~20mW/c㎡.
Is this power high?
Not high, for sure.
Take a small 10 square centimeter solar panel as an example, the power is only 0.15W to 0.2W.
The power of the mobile phone in the middle of the call is more than 5W.
That is to say, if we ignore the power storage function of the mobile phone battery, and instead directly supply power to the mobile phone from the solar panels, even if your mobile phone is covered with solar panels, your mobile phone will still not be able to be turned on.
And what about plants?
Plants use less than 5% of the sun, and most of them are around 1%, which is even more efficient.
What exactly is the utilization rate of ionized bacteria to the sun?
After laboratory tests, the utilization rate of ionized bacteria for solar energy per unit area is much higher than that of existing solar panels, which can reach about 30%.
But that doesn't work.
If the success rate is converted, the ionized bacteria are spread on thin paper, and the power of one square centimeter is about 0.04W, and it is obviously not enough to charge 0.00004 degrees in an hour.
Although the efficiency of photosynthesis is relatively high, ionized bacteria still cannot rely on sunlight alone to power mobile phones and other devices.
The second ability of ionized bacteria is to be able to break down organic matter and obtain energy from it.
In the laboratory, it was found that when ionizing bacteria decompose organic matter, they not only decompose quickly and efficiently, but also absorb high energy, which can absorb up to 50% of the energy.
For example, 10 grams of ordinary biscuits have 45 kcal, or 188.36 kilojoules, which is converted into electricity, i.e. 0.0523 kilojoules.
Ionized bacteria are able to absorb 50% of the energy, which is 0.026 degrees.
The power consumption of the mobile phone for continuous calls is 5W, and the consumption of one hour of use is 0.005 kWh.
A 10-gram cookie can last for 5.2 hours of continuous phone calls.
