Arms Tycoon: Started by cheating on tens of billions of dollars in orders

However, because the number of customer orders is still small, we will put the matter of the arms store aside for the time being.

After nearly a month of research and development.

Located in the factory building of Fengyi Technology Company in Songjiang Entrepreneurship Center.

The first solid-state super battery has finally been developed from the laboratory.

The two teams of Zhao Xuebin and Wen Xiang.

It has successively conquered the positive electrode, solid electrolyte, and carbon-silicon negative electrode of nickel-lithium cobalt-removed batteries.

And this is only the first step.

Next, the two teams will continue to study lithium iron manganese phosphate, a lithium-rich manganese-based battery technology.

But even so.

When the first solid-state super battery was manufactured and tested.

The results were surprising. The electromagnetic density of this new battery has reached 488Wh/kg, which is

200Wh/kg and 110Wh/kg compared to ordinary ternary batteries and lithium iron phosphate batteries.

The density of the new material battery is more than 2 times that of the ternary lithium battery and nearly 5 times that of the lithium iron phosphate battery, which means that under the same volume.

The capacity of nickel-lithium cobalt-free batteries is more than twice that of ternary lithium batteries and nearly five times that of lithium iron phosphate batteries.���

What a concept is this?

In current smartphones, the latest iPhone 6S is equipped with a second-generation lithium cobalt oxide battery with a voltage of 4.2V and a capacity of close to 155mAh/g.

That is to say, if a nickel-lithium cobalt-removed battery is used, the capacity of the new battery is more than three times of the same quality. The iPhone6S battery capacity is 1810mAh, while the new battery of the same quality is more than 5000mAh.

This is still at the same quality.

If you count the volume, because the nickel-lithium cobalt-removing battery removes the cobalt element with a higher mass density.

Using nickel-lithium as the main material means that at the same quality, the new battery is thinner and smaller.

As expected, the new 5000mAh battery is only half the thickness of the 1810mAh battery of the iPhone 6S.

In terms of cost, it is because the removal of cobalt is the most unstable and expensive element.

The cost of new batteries, a new 5000mAh battery is not even half that of an 1810mAh lithium cobalt oxide battery.

At this time, Dr. Zhao explained the technical advantages of the new battery in front of Lin Yi.

Although everyone in this group of people had red bloodshot eyes, they had been studying day and night during this period.

However, their spirits were very high.

Dr. Zhao continued:

"In addition to the above mentioned, the research on solid electrolytes by Dr. Deyi and Dr. Wen’s team, the safety of the new battery can be said to be the best among all lithium batteries!"

With that said, Dr. Zhao did the most intuitive test in front of Lin Yi.

He threw a new high-voltage battery directly into the fire.

If this is an old-fashioned electrolyte battery, as the temperature inside the battery When the critical point is reached, the battery pack will explode and spontaneously ignite.

However, the new battery only emitted billowing black smoke under the 600-degree flame measured by the temperature measuring gun, but it did not burn or explode.

"This is because this new type of solid electrolyte will dissolve once it is heated to a certain critical point.

At this time, the properties of the electrolyte will change, so that the solid electrolyte, which was originally used as an ion carrier to conduct ions, becomes a blocker for lithium particles in the positive and negative directions. Move the blocking object between the poles to protect against power outage!"

"It can be said that compared with ordinary lithium batteries, the new solid-state electrolyte not only has doubled the capacity, but also has epoch-making significance in terms of safety!"

"In addition, the conductivity of the solid electrolyte of the new battery is as high as 3.42mS/cm, which means that the new battery has faster charging and discharging technology than ordinary lithium-ion batteries. It can truly charge in 5 minutes and be used all day long!"

But I heard Dr. Zhao continue to say:

"After we tested the new battery for 2,000 times of charge and discharge, the battery loss did not exceed 3%, which is far lower than all battery products on the market today!"

Hearing his narration, Lin Yi was very excited.

After all, he did not agree with the arms business that could not be exposed. The battery in front of him will be the first major product of his official career.

This has different meanings to him.

Now the first product is so excellent that it surpasses the performance of all lithium batteries on the market.

Although this is a reward given by the system, without Dr. Zhao and others’ research day and night, it would be difficult to rely on Lin Yi alone. Technology turns into results.

Lin Yi is still very grateful to everyone in the Fengyi Technology research team. However

, as he is about to enter the battery industry, he asks:

"How does the battery perform under low temperature conditions?"

According to the existing data, it can be seen that the output performance of lithium ions will be greatly affected when the temperature is below 0℃.

The performance of the battery will be significantly deteriorated at low temperatures below -20℃. The battery can only be used at -40℃. The discharge rate is 30% or even lower than the rated capacity.

This is mainly because under low temperature conditions, the electronic conductivity in the battery is low and the lithium ion diffusivity is poor. At the same time, at low temperatures, the electrolyte has poor conductivity, which increases the internal resistance of the battery and causes polarization. , affecting battery performance.

Dr. Zhao, wearing black-rimmed glasses, said with a smile.

"Well, I was about to tell you this, boss. Because of the use of solid electrolyte, the conductivity of our new battery is much higher than that of lithium batteries in the world.

Under low temperature conditions, the impact of solid electrolyte is much lower than that of liquid electrolyte.....

We have conducted corresponding experiments and found that the new battery is almost unaffected at 0 to minus 10 degrees.

However, at minus 10 to minus 20 degrees, the output performance of the new battery is reduced by 5%.

This is only the case under extreme conditions, that is, low temperatures.

At minus 40 degrees, the performance will plummet to 80%, but even so, the performance of our battery in the same environment is far better than that of other lithium batteries....

！"

As soon as Dr. Zhao finished speaking, Lin Yi immediately clapped his hands.

"bang bang bang...！"For a moment, the entire research room burst into fierce applause.
