With high technology in hand, we will lead China to break out of the universe

He took the phone solemnly, his hands trembling slightly.

Su Fan patted his shoulder and comforted him: "Don't be nervous, I will also work with you on research and development."

The two began the research and development of all-solid-state batteries.

Among the batteries in the world today, lithium batteries have the highest energy density. Depending on the electrolyte, they are divided into liquid batteries, semi-solid batteries, and solid-state batteries.

Among them, the highest energy density of liquid batteries is 0.3 kWh per kilogram, the energy density of semi-solid batteries is 0.36 kWh per kilogram, and the energy density of solid-state batteries can theoretically reach 0.4 to 0.9 kWh per kilogram.

But solid-state batteries aren't yet on the market, so whether they can achieve this energy density is unknown.

Moreover, lithium-ion batteries have a fatal flaw, which is that they are prone to explosion.

The news reports of electric vehicles parked in corridors causing fires are almost all caused by lithium battery explosions.

There were also incidents of spontaneous combustion of new energy vehicles and mobile phone explosions N years ago, all of which were caused by lithium batteries.

The all-solid-state battery developed by Su Fan and his team this time is not a traditional lithium-ion battery, but a battery composed of a mixed compound of sodium ions, potassium ions, carbon, silicon and other elements.

The principle is that both compound molecules can simulate biological discharge phenomena.

(I can’t continue writing this, it’s really cool technology anyway)

The energy density of all-solid-state batteries can reach a terrifying 10 kWh per kilogram.

Moreover, it is extremely resistant to severe cold and high temperatures, and the battery capacity will not be lost at temperatures between -70 degrees Celsius and 110 degrees Celsius.

It won't burn or explode even if put in fire!

No burning or explosion will occur if you cut it with scissors, pierce it with an awl, throw it into water, etc.!

All-solid-state batteries are so excellent that once they are developed, all other batteries on the market will be eliminated!

Because the production cost of all-solid-state batteries is very low, 100 yuan per kilogram, which is converted into power capacity, the cost per kilowatt-hour is only 10 yuan, which is a dimensionality reduction attack on other batteries on the market.

The cost price of lithium batteries on the market is about 600 to 800 yuan per kilowatt-hour because of the large fluctuations in the price of lithium, a raw material.

There is no harm without comparison.

When Zhang Minghan saw the introduction in the information, his three views were shattered. This is not scientific!

However, as the research progressed, this battery that destroyed everyone's worldview was slowly produced!

"Test and calculate the battery density!" Su Fan commanded in the laboratory.

After a week, the first finished product was finally produced.

I saw a black cube that looked like carbon and metal lying quietly on the laboratory table.

"The test calculation is completed, the energy density..." Zhang Minghan was a little bit unbelievable.

"Energy density is 1.8 kWh per kilogram!"

"It's too far off, let's continue the experiment." Su Fan frowned.

A week of laboratory life made him feel very uncomfortable. It seemed that he had to lie down and be the boss. Laboratory work was not suitable for him at all.

The two began their boring research and development work again.

It is hard to imagine how difficult scientific research is, and this is based on the premise that all the data is available.

Those scientific researchers who are crossing the river by feeling the stones step by step, without any reference, cannot determine the results, they are the ones who truly deserve everyone's respect!

Another week has passed.

In the laboratory, Zhang Minghan was nervously testing the finished battery products.

Suddenly, he cheered: "Boss Su, it's a success!"

"Battery energy density: 10 kWh per kilogram!"

“We made history!”

Su Fan grinned, wiped the sweat from his head and said, "This is just the beginning. From now on, we will continue to make history!"

Zhang Minghan nodded seriously. At this moment, his admiration for Su Fan reached its peak.

"Pack up, then go back to the dormitory to wash up, and come to my office at three in the afternoon."

Su Fan was exhausted. Two weeks of high-intensity R&D work was too tiring!

He must have a good sleep at noon.
