New battery developed by American manufacturers -Lithium - Ion Battery Equipment

Recently, American media reported that an American battery company named Sakti3 has successfully developed a new type of battery with energy density twice that of the existing lithium ion battery, and said it would like to cooperate with Tesla. As for Tesla, which wants to build its own battery factory, what will it do with this proposal and whether it will be included in its own supply system? Today, we might as well talk about this topic.

● Who is Sakti3?

Sakti3 is an unknown small company for most people, with its headquarters in Michigan. Dr. Ann Marie Sastry, CEO of the company, has served as the teaching research and management of Michigan University (University of Michigan) for 25 years. Although the company has only been established for seven years, it has obtained $30 million of venture capital, including General Motors of the United States. The reason for attracting investors may be that the project it is researching is a hot solid state lithium-ion battery technology, which is also regarded as one of the important means to replace the existing lithium-ion battery for electric vehicles.(Lithium - Ion Battery Equipment)

● What is the difference between solid state lithium-ion batteries?

Lithium ion batteries are used to supply power for electric vehicle driving. Traditional lithium ion batteries usually use liquid as electrolyte. This structure is likely to cause adverse chemical reactions on the battery cathode, thereby reducing the stability and service life of the battery. The biggest innovation of solid state lithium-ion batteries is that they replace the liquid electrolyte in traditional lithium-ion batteries with solid state ions, which can effectively prevent the occurrence of adverse chemical reactions, and can be compatible with a wider range of battery chemical processes, so as to improve the power and energy storage density of the batteries. In fact, it is the increase of vehicle mileage and service life.

● Advantages of new battery

The new battery declared successful this time uses solid state lithium-ion battery technology, which can nearly double the range of electric vehicles. If large-scale production is achieved, the cost is far lower than the existing lithium-ion battery for vehicles. If all 18650 lithium ion batteries used in Tesla MODELS60 kilowatt hour models are replaced by this new type of battery, the cost of the battery pack is only 6000 dollars (about 36900 yuan), and the range can be increased to 722km (390km for domestic models at present). It can be seen that if the solid state lithium-ion battery technology becomes mature, the short board of electric vehicle range will be further weakened.

● Supply Tesla?

Dr. Ann Marie Sastry said that Sakti3 wanted to manufacture a new 60 kilowatt hour solid state lithium-ion battery for Tesla MODELS electric vehicles, but it is unknown whether Tesla, which is building its own factory, can accept this. At present, the battery used in Tesla electric vehicles is 18650 lithium-ion batteries. Although there is a big gap between the performance of Tesla electric vehicles and the new solid state batteries, the battery management system that Tesla is proud of is completely centered on. The use of new batteries will undoubtedly have a huge impact on the existing technology system. Not long ago, Tesla released many of its patents in the battery field, which is also intended to enable more manufacturers to participate in the research and development of existing technology and further expand the market share of related technologies. To a large extent, the involvement of new battery technology runs counter to this goal.

In addition, as the core component of electric vehicles, the battery is unable to achieve self-sufficiency, undoubtedly laying a huge hidden danger for the company's future development. This must be clear to Tesla. At present, all 18650 batteries used by Tesla are from Panasonic, and this single supply mode has also made Tesla hard to say for a long time. Panasonic has raised the price of 18650 batteries to US $3.5 per battery since the date of supply, with a growth rate of up to 75%. Whether the price will continue to rise in the future is still in the hands of Panasonic. The reason why the price gap between the front and the back is so wide is obviously the disadvantage caused by relying entirely on outsourcing. It is hard to tell whether Sakti3 will be the second Panasonic to "rip off".
