Shenhao started after the college entrance examination

National Convention Center, Dream Future Graphene Technology Group aluminum-ion battery press conference site.

Yao Hailan took the initiative to chat about various issues with sodium-ion batteries, and stated that the second press conference of Dream Future Graphene Technology Group was due to the fact that sodium-ion battery technology has been questioned.

"Before the aluminum-ion battery technology conference officially begins, I will reveal three key issues."Yao Hailan continues to spoil the story.

"First, regarding the issue of technology ownership, sodium-ion battery technology was previously developed by Shanxia Group and shared with our Dream Future Graphene Technology Group. Everyone is full of doubts about such technology sharing, so the aluminum-ion battery technology released this time is 100% Developed and owned by We Dream Future Graphene Technologies Group. Yao Hailan explained.

The original developer of the aluminum-ion battery technology has died, and the aluminum-ion battery technology has fallen into the hands of the Dream Future Graphene Technology Group. So it is developed and owned by the Dream Future Graphene Technology Group, so there is no problem, right?

"Second, the performance parameters of aluminum-ion batteries are very powerful, far exceeding sodium-ion batteries and exceeding ordinary lithium-ion batteries, so there is no need to worry about the commercialization of aluminum-ion batteries. Yao Hailan added

"Finally, there is the issue of production capacity. Since aluminum-ion batteries are self-developed by our Dream Future Graphene Technology Group, aluminum-ion batteries will be compatible with the production line of graphene lithium-ion batteries. We will quickly establish a production base for aluminum-ion batteries and strive for the first year..."Speaking of this, Yao Hailan stopped abruptly.

"I almost said too much. These things will be answered one by one by Mr. Zhao Kaixin, a colleague from the technical department. Next, welcome to Mr. Zhao Kaixin."Yao Hailan made a temporary guest appearance as the host.

Zhao Kaixin still appeared on stage wearing a POLO shirt and casual pants. When he walked onto the stage, Yao Hailan had already quietly left the stage.

"Hello everyone, we meet again. I am Zhao Kaixin, the technical director of Dream Future Graphene Technology Group. I am very happy to meet you again."Zhao Kaixin took the initiative to say hello.

There was warm applause from the audience.

"What do you want to know most about aluminum-ion batteries?"Zhao Kaixin asked the news media industry professionals at the scene.

The scene immediately gave out mixed answers.

"Ahem!"Zhao Kaixin deliberately coughed twice to attract attention,"Everyone, please be quiet for a moment. Let's do a small investigation."

As Zhao Wanxi finished speaking, a QR code was displayed on the screen wall behind Zhao Kaixin.

"Please scan this QR code and vote. We will explain the aluminum-ion battery technology in detail based on the voting results." Zhao Kaixin explained.

The news media practitioners on the scene quickly began to scan the QR code.

After the QR code recognition was a single-choice voting:

1. Energy density

2. Battery life

3. Charging speed

4. Operating temperature

5. Battery cost

6 , battery price

7, battery production capacity

8, sales area

There is only a single choice among the eight options. A large number of local news media practitioners chose the first option, and some overseas self-media people chose the eighth option.

Dreaming about the future of graphene Technology Group is a company with sales discrimination and has implemented different sales strategies in different regions, including different prices and even direct sales bans.

Therefore, overseas self-media people want to know the eighth option and see Dream Future Graphene What kind of sales methods will the technology group use for aluminum-ion batteries?

In just one minute, the voting ended. The first choice with the highest vote rate was the first choice, and energy density was the most concerned thing.

Zhao Kaixin looked at the voting results, He didn’t hold back and said directly,"Since everyone wants to know the energy density of aluminum-ion batteries most, let’s first introduce the energy density of aluminum-ion batteries."

As Zhao Kaixin finished speaking, the energy density information of five types of batteries was displayed on the screen wall behind him.

……

Overall system of graphene lithium-ion battery: 450wh/kg

Overall system of ternary lithium battery: 200wh/kg

Overall system of lithium iron phosphate battery: 120wh/kg

Overall system of sodium-ion battery: 95wh/kg

Overall system of aluminum-ion battery: 220wh/kg

……

"At present, the graphene lithium-ion battery with the highest energy density is still the graphene lithium-ion battery developed by our group. In the case of the overall system, the energy density of our graphene lithium-ion battery can reach 450wh/kg, which is more than twice that of the overall ternary lithium battery system. above."Zhao Kaixin first reviewed the energy density of graphene lithium-ion batteries

"The energy density of the aluminum-ion battery we released today has also reached 220wh/kg, which exceeds 10% of the energy density of the overall system of ternary lithium batteries and can completely replace ternary lithium batteries in terms of energy density." Zhao Kaixin explained.

The biggest reason why sodium-ion batteries cannot replace ternary lithium batteries is that the energy density of sodium-ion batteries is too low!

Now the energy density of aluminum-ion batteries is higher than that of ternary lithium batteries. From the perspective of energy density , it can indeed replace ternary lithium batteries.
