Shenhao started after the college entrance examination

National Convention Center, Dream Future Graphene Technology Group’s sodium-ion battery launch conference.

Zhao Kaixin, the director of the technical department, threw a big bomb at the beginning and directly stated that the sodium-ion battery parameters to be released by Dream Future Graphene Technology Group are powerful, which will subvert the old market and create a new business environment.

After Zhao Kaixin threw the king bomb, the screen wall behind him displayed part of the sodium-ion battery information.

……

Life advantage:

Sodium-ion battery: 4500+ cycles

Ternary lithium battery: 1000+ cycles

Lithium iron phosphate battery: 2000+ cycles

Note: Given that the research on sodium-ion batteries has just started, the ultimate life cycle of sodium-ion batteries will be in the future. There is room for expansion

……

"Has anyone heard of lead-acid batteries?"After Zhao Kaixin released information about the life advantages of sodium-ion batteries, he took the initiative to ask questions.

However, Zhao Kaixin did not need anyone to answer. He asked and answered questions by himself,"Lead-acid batteries are the batteries used in the automotive industry. At present, the automotive industry is still widely used. Use lead-acid batteries"

"The life cycle of lead-acid batteries is about 300 times. Under normal circumstances, it can be used for about 3 to 5 years, but our sodium-ion batteries can have a life span of at least 20 years, which will cover the life cycle of most cars.." Zhao Kaixin added

"The second is the safety at low and high temperatures. The first-generation sodium-ion battery has the same performance as lead-acid batteries, and is better in self-discharge. Even if it is parked for a long time, the battery will not lose power."Zhao Kaixin continued to introduce

"After our first-generation sodium-ion battery is put into production, we will cooperate with a large number of automobile manufacturers to replace the position of lead-acid batteries in the automobile industry."Zhao Kaixin expressed his ambition.

This is to subvert an old market!

The market of the global automobile industry is very huge. The total global automobile sales in 2020 will be 78 million vehicles. In addition, there are currently more than 1 billion vehicles in the world. If Na Ion batteries can replace lead-acid batteries, which will be a successful first step.

This step can at least allow sodium-ion batteries to survive!

Like lead-acid batteries, it has a low life cycle, poor self-discharge performance, and low energy density, but It has high temperature tolerance, high safety and stability, thus surviving in the automotive industry.

Even the hot lithium battery cannot replace it!

Now Zhao Kaixin expressed his dream that the Graphene Technology Group will use sodium-ion batteries to enter the future The automobile industry represents the foundation and development direction of sodium-ion batteries.

Only with the foundation and development direction can sodium-ion batteries continue to be researched

"Sodium-ion batteries also far surpass lithium batteries in terms of battery capacity retention." Zhao Kaixin also mentioned the second advantage of sodium-ion batteries.

He added,"Our own graphene batteries are not within the comparison range. After all, the performance of our own graphene batteries is very powerful!"

There was good-natured laughter at the scene.

Because the graphene batteries of Dream Future Graphene Technology Group are indeed lithium batteries.

……

Battery capacity retention rate:

1,000 charging cycles, the specific capacity retention rate is as high as 94.6%.

Note: The industry standard specific capacity retention rate for 1,000 cycles is only 80%

……

Conventional lithium batteries, whether ternary lithium batteries or lithium iron phosphate batteries, cannot achieve the high specific capacity retention rate of sodium-ion batteries.

Taking ternary lithium batteries as an example, under normal circumstances, the remaining battery capacity after three years is about 80%.

A higher battery capacity retention rate means longer battery life, lower long-term use costs, and a better user experience.

For example, a ternary lithium battery with a battery capacity of 100 kWh will only have 80 kWh of battery capacity left after 1,000 charging cycles, but a sodium-ion battery can have more than 94 kWh left.

This is a very powerful advantage!

Of course, as Zhao Kaixin added, the performance parameters of sodium-ion batteries are only compared with ordinary lithium-ion batteries, not with their own graphene batteries.

After all, if the graphene batteries of the Dream Future Graphene Technology Group are allowed to participate in the comparison, then just wait and see!

"Our sodium-ion batteries have a third, very critical advantage!"Zhao Kaixin pressed the remote control and let the screen wall behind him display the corresponding information.

……

High energy conversion rate!

……

This time, the information only displayed a line of text information without any data information. The media on the scene paid close attention to it. After all, everyone has a very sensitive sense of news.

"Are you curious, how high is the high energy conversion rate?"Zhao Kaixin asked with a smile.

The scene once again gave out good-natured laughter, because everyone really cared about this issue.

"Regarding conversion efficiency, let’s first compare ordinary lithium-ion batteries. I’m talking about ordinary lithium-ion batteries. Our own graphene battery products are not within the scope of discussion, okay?"Zhao Kaixin is making fun of me again.

After all, the graphene battery of Dream Future Graphene Technology Group is very strong in terms of charging efficiency. It is not like a lithium battery, but more like some legendary black technology.

Well!

Graphene batteries are inherently black. science and technology!
