In 1799, the Yidian physicist Volt immersed a zinc plate and a tin plate in salt water and found that electric current was passed through the wire connecting the two metals. So he padded many zinc plates and silver plates with salt water soaked velvet or paper sheets flat. When touching both ends with his hands, he felt a strong stimulation of the current. Volt successfully made the world's first battery, the "volt stack".

Therefore, since the battery was released to the present, it has a history of more than two hundred years.

But over two hundred years have passed, the energy density of the battery has not been significantly improved.

The earliest widely used battery was a carbon-zinc battery, with an energy density of about 30-100h/kg. Its characteristic is that it can only be used once, but it is cheap.

The lead-acid battery invented later was more widely used, with an energy density of about 80-120h/kg, but it can be recharged and discharged repeatedly, and is cheap, and quickly became the mainstream. It has been popular for hundreds of years and has not been eliminated yet.

However, the energy density of lead-acid batteries is too low, so lithium batteries came into being in the 1960s, with energy density as high as 150-250h/kg, which is twice that of lead-acid batteries.

Some high-performance lithium batteries can even reach 300h/kg, and in theory it has the possibility of reaching 1000h/kg energy density.

But theory is just theory.

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

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

Moreover, due to complex technology, safety, high production costs, lithium batteries were not promoted on a large scale until the 21st century and gradually became the mainstream.

In addition, there are many development paths for batteries, with higher energy density, longer life and safer batteries in the future, and all institutions are developing.

Such as metal-air batteries.

The representative of this type of battery is zinc-air battery. The specific energy of zinc-air battery is 4 to 6 times that of lead-acid batteries and 1 times greater than that of lithium-ion batteries. 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-volume is about 300 to 500 yuan/kvah, which is lower than lead-acid batteries. It is safe and reliable. Even if there is open flame, short circuit, puncture, impact, etc. outside, there will be no combustion or explosion.

But even with so many advantages, zinc air batteries have some fatal disadvantages. Their cost is relatively high and the charging process is complex. The actual service life is short, 1 to 2 years. This is mainly not because of the poor electrochemical performance of the battery, but because of the impact of the battery structure; the mass production and processing technology are not mature enough. This is mainly because of the manufacturing of catalytic films and waterproof and breathable films, which mostly require semi-mechanical operation, and there are some manual factors, resulting in differences in electrode performance.

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

In addition, there are all-solid-state batteries, nanocrystal lithium-ion batteries, fuel cells, etc. at least dozens of batteries.

Some of their energy density have been announced to reach 500h/kg, some have announced to exceed 800, and some have exceeded 1,000. It is exciting, as if they have seen the hope of the arrival of the high-energy battery era.

But... it's all over.

Laboratory performance does not mean actual performance.

Products in the laboratory may not necessarily become market products.

In the current market, the one with the highest energy density that can be purchased is a ternary polymer material (li(nin)o2) combined with nickel-cobalt-manganese oxide as the positive electrode.

Among such batteries, a domestic manufacturer combined graphene technology to achieve the highest level of the world's energy density of 550h/kg. It caused a sensation all over the world at that time and was believed to be the new energy era coming soon.

But it may be too early to be happy.

Because the energy density of gasoline is as high as 12,000h/kg, the best ternary battery has an energy density of only 4.58% of gasoline, less than one-twentieth.

Three-unit battery technology is not yet time to replace traditional energy.

Just saw a glimmer of hope.

The successful development of Xinghai Technology's "High Energy No. 1" battery directly realized this hope.

In 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, impact resistance, high temperature resistance, good stability, and more charging times than other types of batteries."

"For example, the best quality ternary battery has a charging life of 1,500 times. After about 800 times, the battery capacity will drop to 80%; but the number of charging times of 'High Energy No. 1' can reach 10,000 times, and only after 5,000 charging-discharge cycles, the battery capacity will drop to about 80%.

"And the 'High Energy No. 1' battery integrates the most advanced graphene fast charging technology. For example, the 10,000 mAh mobile phone battery in my hand supports up to 100 watts of fast charging technology. It only takes 6 to 10 minutes to fully charge the battery, and there is no need to worry about excessive heat."

Zhao Qiang held the small battery and continued: "As for its energy density, due to the use of a brand new nanopolymer material, as the positive electrode of the battery, its energy density has actually been measured to reach 1500h/kg."

"This is six or seven times that of ordinary lithium batteries! It is equivalent to one-eighth of gasoline."

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

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

"So from the perspective of energy utilization efficiency, the actual performance of the 'High Energy No. 1' battery is equivalent to one-third of the gasoline."

One third of gasoline!

This is quite amazing.

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

Because compared with fuel-fueled cars, the electric motors of electric cars are simpler and have lighter weight. With some accompanying mechanical structures, hundreds of kilograms of mass are saved.

Complex transmission structures such as gearboxes have been cancelled.

The overall weight loss is at least 200 kg or more.

Of course, in order to achieve a range of equivalent to a fuel vehicle, the number of battery packs will definitely increase. According to the mass of 50 kilograms of gasoline, a 150 kilogram "High Energy No. 1" battery must be equipped with a 150 kilogram portion to achieve the same range.

even so!

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

So the battery life will only be stronger.

Because of the most advanced fast charging technology, the large-volume battery cell can be fully charged within half an hour to one hour, and the waiting process will not be particularly long.

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

At least in the automotive field, for comprehensive considerations such as environmental protection, convenience of use, battery life, safety, and cost.

With the advent of "High Energy No. 1", people can hardly find a reason to reject electric vehicles.

Once this battery is released, it can be imagined that the sensational impact it will cause will be even more unimaginable; the global shocks in multiple fields caused will inevitably put huge pressure on Xinghai Technology.

So the question before Chen Jin is: Should I detonate this bombshell?
