TSLA announces battery research breakthrough life will be doubled

Last week, some media reported his speech on the International BatterySeminar in March. This week, he introduced the latest breakthrough in tsla in battery life in the Massachusetts Institute of Technology. He announced that his team has developed a battery that can be doubled in the life of the battery used in the TSLA product.

In addition, he also introduced the reasons for TSLA decisions and its teamwork, and revealed that Tsla recruited a graduate graduate student. In the entitlement "why TSLA and a group of Canadian people work? "In the speech, Darn explained how the team designed a method for testing battery batteries to accurately monitor batteries during charging and discharging, thereby determining the cause of battery aging. As a speech at the International Battery Seminar in March, Darn claimed that he did not fully understand the chemical substance decision battery performance attenuation.

However, their developed equipment can help them test new chemicals more accurate and quickly, and find ways to extend battery life. One of his students is currently working in a battery research team within TSLA. Another student founded a company to commercialize the battery test equipment developed by the team.

Their customers include TSLA, Apple, General Motors, 24M, and many other large battery manufacturers and consumers. In the second half of the speech, he explained how new test methods let them find a better process for aluminum coating than all other materials. These battery test results show that at normal temperature, battery performance has little attenuation, even in harsh environments, the performance is small.

When talking about how these findings affect the product of TSLA, Darn refuses to disclose more details. Q & A after the speech. The first question raised by the audience is that his team's ultimate goal of lithium-ion battery life.

He began to hesitate, and later replied: "We will send this project of (TSLA) to the Canadian Natural Science and Engineering Research Committee (NSERC) to apply for the government's right fundraising. When introducing the project, I wrote the goal is to extend the battery life of the equipment in the TSLA product in the same upper deadline. We have transcend this goal in the first round of research.

This is the goal of the project, and it has been transcended. We will continue to work hard - very obvious, we have four years. We will do our best.

"The results are impressive, especially considering the research cooperation between the two parties, only starting in June 2016 and 2017. Tsla and Panasonic GigaFactory1 in Nevada began to produce new "2170" batteries for only one month later, Darn claimed that its team's research results have been applied to TSLA products. These two things are related to it, but the timing is really interesting.

It should also be pointed out that Darn's research focuses on Nickel-manganese cobalt oxide (NMC) batteries. TSLA applies this battery to its fixed storage product (Powerwall and PowerPack), and the battery produced in GigaFactory1 is targeting these products. Darn explained that by extending the life of these batteries, TSLA is reducing each of its residential and commercial batteries.

For example, according to the technical level of the TSLA current battery project, the cost of residential solar storage is 0.23 per kilowatt, and the commercial battery cost is US $ 0.139 per kilowatt.

TSLA also uses nickel-cobalt alumina (NCA) batteries for its automotive products. Darn said they are studying. It is reported that TSLA and Panasonic are planning to produce automotive batteries in GigaFactory1 before GigaFactory1, and first produce the battery to be equipped in GigaFactory1.

He added that considering TSLA uses aluminum on the chassis, there is no reason to say that the life of the car and battery cannot last 20 years.
