"400Wh/kg." Liao Changxue sent out the battery energy density of the laboratory in the group. He said: "It should be because the energy density is too high. This is not the technical index of Panasonic 18650, but it exceeds NCA21700!"

Liao Changxue became more and more excited!

He was in the laboratory and saw with his own eyes the energy density tested after the laboratory battery samples came out. It was indeed 400Wh/kg, while the highest single energy density of the Panasonic 18650 battery was only 250Wh/kg.

At present, the laboratory is still testing the durability, lifespan and safety of batteries, and in order to complete Tesla's orders, the laboratory actively reduces the battery density.

Liao Changxue is also an expert in this industry. It is the first time he has seen the company do this. After having the world's first battery technology, he does not publicize, celebrate, or produce. Instead, he low-key reduces the density of batteries to complete past orders.

Liao Changxue absolutely can't stand this kind of behavior, he must express the excitement in his heart.

Not every battery factory can achieve a battery energy density of 400Wh/kg.

The people in the group couldn't sit still. Here are all the top talents in the battery field of Xiaguo. In addition to the front-line technical experts in the factory, there are many professors from university research institutes that have cooperative relations with battery companies.

Panasonic's lithium battery NCA21700 with the highest energy density has an energy density of 340Wh/kg, and the output is not very large. It is specially supplied to Tesla. This battery is also the best battery in the global commercial field.

In the group, many technicians and experts regard Panasonic NCA21700 as the goal of catching up and surpassing.

Now Pangu Technology has succeeded? And it's that easy.

"What about the cost? Compared to Panasonic."

"How long can you live?"

"Any mass production plans?"

"Old Liao, I want to report this to the top! If Pangu Technology makes a domestic battery! Is it possible to cooperate with us." Li Yudong, a former colleague and friend of Lao Liao, chief technician of BYD Battery Company, sent a private letter to Liao Changxue.

BYD is also a leader in the lithium battery new energy industry internationally, and its technology has also touched the latest lithium battery of 235Wh/kg.

If you count the price advantage, BYD can compete with Panasonic's most conventional 18650 battery in the market.

But when Panasonic threw out the NCA21700, BYD felt a little labored.

The current cost of NCA21700 is relatively high, and no other car companies except Tesla have purchased it, but who knows what the future will be like?

Panasonic has mastered the technology, and it is only a matter of time before reducing costs and increasing production. BYD has not yet mastered the technology, which is more troublesome.

Who knows that Panasonic has not established a firm foothold at the level of 300kw/h, and a company that has never been involved in the battery industry can buy Panasonic's 18650 factory and produce batteries that are more awesome than 18650 within a week!

Liao Changxue thought of the words of the boss Xiao Ming and replied, "Welcome to visit."

Of course, more people also think that Liao Changxue is bragging! 400 energy density so easy to do? If so, under the global appeal of new energy vehicles, aren't auto companies seeking to learn from Liao Changxue's battery factory?

"Really? Can we come to visit and study?"

"Don't say four hundred, even three hundred will make a fortune!"

"As for the cost, you haven't said the cost yet."

Liao Changxue said proudly: "The cost is only lower than that of Panasonic 18650."

"We're coming to visit and study!"

"You're not allowed to visit! I'm bragging about you!"

"Of course you are welcome!" Liao Changxue took the initiative to invite.

Finally, everyone in the group agreed to form a team to visit and study two weeks before the order was delivered to Tesla.

In fact, Liao Changxue still has his own plans. Even though Xiao Ming said that the production line will be closed after completing Tesla's orders, he still hopes to work harder to keep the production line.

Many experts in the battery industry in Xiaguo have worked hard for more than ten years for the energy density of more than ten or twenty points. Now Xiaguo's technology has been effective, but it is necessary to turn it off or not. Liao Changxue's heart is really hard .

Jiangcheng, Pangu Science and Technology Park, Quantum Physics Laboratory.

After discussions with Xiao Ming and Xu Limin's team, they decided to open the micronucleus battery laboratory.

At this time, Xu Limin looked at Xiao Ming with rather complicated eyes. He didn't know how many secrets his boss was hiding.

Micronuclear batteries are not unfamiliar scientific research projects.

On the spacecraft, it is used in fields such as human heart pacemakers.

But at present, the technology still faces two problems.

One is the relationship between energy and mass.

As with fuel cells, energy is proportional to battery mass.

The larger the energy, the larger the volume and mass of the nuclear battery.

Because the electrons of other nuclear batteries need to be captured by semiconductor materials, the semiconductor materials will be seriously consumed during the capture, so they must be large in size.

In this way, micronuclear batteries are not as convenient as chemical energy batteries such as lithium batteries and nickel batteries.

That's why most nuclear batteries will be used in aerospace and not in human daily life, because with current technology, you can't make a nuclear battery that drives a computer as small as a lithium battery.

The nuclear battery used in the pacemaker uses plutonium 238, which is also small in size. This is because the electrical energy used for pacing the heart is also very small, and this electrical energy cannot drive computers and mobile phones to run.

Another is the safety issue. A small dose of plutonium 238 in a closed metal casing will not cause radiation pollution to humans, but a nuclear battery with a larger energy will definitely cause radiation damage to humans.

There is still a way to prevent radiation, then add a radiation-proof casing, which is usually heavier than the battery itself.

However, using radioactive materials that have no radiation hazards to the human body, such as small doses of tritium, potassium 40, etc., the electrons overflowing from these radioactive materials will generate very little electricity after being captured. There will be.

The above two problems are the current bottlenecks for human micronuclear batteries to shift from military and aerospace applications to civilian use.

This kind of bottleneck is not to do two experiments, just a few papers can be successful. It takes certain leap forward progress in basic disciplines such as new materials science and physics to turn the idea into reality.

The principle of the micronucleus battery technology that Xiao Ming exchanged is actually very simple.

The radioactive material undergoes beta decay, overflowing electrons, which are captured by the semiconductor material to form an electric current.

So here comes the problem. Micronuclear batteries require three raw materials, radioactive elements, semiconductor materials, and a protective casing.

Under Xu Limin's repeated questions, Xiao Ming gave the answer.
