Shenhao started after the college entrance examination

If we say that the graphene batteries currently developed by Dream Future Graphene Technology Group have not yet left the camp of lithium-ion batteries, the battery cells still use lithium metal as the core raw material.

So there is an essential difference between lithium-ion batteries and aluminum-ion batteries!

What if Anliang obtains aluminum-ion battery technology and then integrates graphene battery technology to combine the performance of the two?

"Lao Wu, have you heard of aluminum-ion batteries? An Liang asked casually.

Wu Chunsheng answered affirmatively,"Of course I've heard of it!" That is the future development direction of batteries. Unfortunately, I have done relatively little research on aluminum-ion batteries. I only know some basic technical conditions and cannot solve technical difficulties."

"Are aluminum-ion batteries the future development direction?"An Liang looked at Wu Chunsheng in surprise.

Wu Chunsheng is an expert in graphene battery technology, right?

Logically speaking, aluminum-ion batteries are competitors of graphene batteries. Wu Chunsheng should belittle aluminum-ion batteries. As a result, this This guy actually said that aluminum-ion batteries are the future development direction?

Wu Chunsheng definitely confirmed,"Yes, judging from the current development trend, aluminum-ion batteries are the future development direction. Because the energy density of lithium-ion batteries has always been difficult to increase, and lithium is a rare light metal, its reserves are quite limited."

As a rare metal, lithium content in the earth's crust is only 0.0065%. In addition, Xia is a country with a scarcity of lithium metal. About 85% of the lithium metal needs to be imported, which may be choked by the amount of raw materials.

"Aluminum-ion batteries are batteries developed based on metallic aluminum. According to the technical information that has been disclosed in the industry, aluminum-ion batteries have many advantages!"Wu Chunsheng added

"For example, the advantage of battery life, judging from the technical papers that have been published so far, the life of aluminum-ion batteries far exceeds the current lithium-ion batteries."Wu Chunsheng gave an example

"The second advantage is safety performance!"Wu Chunsheng continued to list the advantages of aluminum-ion batteries,"The chemical properties of metallic lithium are very active. Whether metallic lithium is put into water or a liquid containing water, it may cause the explosion of metallic lithium."

"Current lithium-ion batteries are at risk of spontaneous combustion and explosion. This is actually because the chemical properties of metallic lithium are too reactive."Wu Chunsheng added

"However, aluminum-ion batteries do not have such dangerous properties. After all, the chemical properties of metallic aluminum are quite stable, and at most they will only suffer from oxidation problems."Wu Chunsheng explained

"The third obvious advantage is cost. This advantage is also a very critical advantage. The reserves of aluminum metal are very huge. Aluminum products are used in all aspects of the human world. It is almost a readily available metal material."Wu Chunsheng continued to list the advantages of aluminum-ion batteries.

Aluminum is the third most abundant element in the earth's crust, accounting for approximately 7.73% of the total content, far exceeding the content of lithium.

"At present, the price of our group's purchase of metallic lithium raw materials has reached 1.3 million yuan per ton, but now the price of metallic aluminum is only 20,000 yuan per ton. The raw material costs of the two are worlds apart!"Wu Chunsheng sighed

"Taking Tesla's Model 3 as an example, its battery module cost is divided into two parts. The cost of a 76.8 kWh battery cell is about US$7,000. The other part is battery safety protection armor, temperature control system, comprehensive power management system, etc. The packaging cost is also about $7,000."Wu Chunsheng explained the relevant data.

"If aluminum-ion batteries are used to replace lithium-ion batteries, the cost of the battery cells will probably drop to about US$120 to US$150."Wu Chunsheng continued to add data.

"As for the packaging cost, because of the high safety of aluminum-ion batteries and the fact that aluminum-ion batteries can be packaged in polymer form, the packaging cost can also be significantly reduced, possibly from a high of US$7,000 to less than US$500."Speaking of this, Wu Chunsheng had some sighs.

"If other conditions are ignored, with the same battery capacity, the final cost of an aluminum-ion battery may be only one-tenth that of a lithium-ion battery. What kind of exaggerated advantage is this?"Wu Chunsheng sighed again

"If the technology of aluminum-ion batteries matures and the energy density can reach the current level of lithium-ion batteries, it will completely defeat lithium-ion batteries with its excellent safety and low cost, and even our graphene batteries may be included. Disrupted by aluminum-ion batteries."Wu Chunsheng said with a sense of crisis.

"If coupled with the significant reduction in the difficulty of mining and smelting metal aluminum, and the crushing advantages of aluminum-ion batteries over lithium-ion batteries in terms of environmental hazards, I do think that aluminum-ion batteries are the future development direction. Once aluminum-ion batteries Once the battery is born, lithium-ion batteries will enter the sunset stage."Wu Chunsheng concluded.

Zhao Wanxi agreed,"According to Mr. Wu's analysis, the advantages of aluminum-ion batteries are indeed too great. Not to mention ordinary lithium-ion batteries, even our graphene batteries, I'm afraid. It cannot effectively compete with aluminum-ion batteries."

Wu Chunsheng answered on the side,"The most we can do is ensure that we occupy a very small amount of the high-end market while ignoring costs in the high-end field."

After listening to Wu Chunsheng's analysis, An Liangzhi once again raised the priority of aluminum-ion battery technology. This time, he must get the aluminum-ion battery that is about to be born in Sila, India!
