Recently, according to overseas media reports, Panasonic plans to invest 700 million US dollars to upgrade its production facilities in Japan, after which it plans to start production of Tesla 4680 batteries next year. At the same time, Panasonic said in a statement that a prototype production line will be deployed for new batteries. Subsequently, Panasonic's new CEO Yuki Kusumi said that if the test production is successful, Panasonic is ready to make a "big investment" in the production of Tesla's new battery.
In fact, as early as before, Tesla had mentioned the new battery it was developing at the Battery Day in 2020 - the 4680 battery, although Tesla did not announce how much battery life the 4680 battery could achieve at that time, but from Musk's introduction, we can know that the 4680 battery will be a revolutionary breakthrough for Tesla.
The full name of the 4680 battery is the 4680 type electrodeless ear battery, compared with the current mainstream car battery, its advantages are very clear. The increased heat generation and dissipation capacity of the battery will increase the cycle life of the battery. Battery energy density increases, mileage increases, in short, the 4680 type electrodeless ear battery is not only durable, but also the mileage has been significantly improved.
The new 4680 battery costs less and has a larger capacity than the battery tesla uses today. Compared with the current battery, the new battery will have a larger battery specification, which can help Tesla's models increase the range by about 20%. As for the new production line, there are reports that Panasonic may produce new batteries at its plant in Goyama Prefecture.
In fact, not only Panasonic, but also Ningde Times, Samsung, LG have made it clear that the production of 4680 batteries for Tesla is their goal, which shows that 4680 batteries do have very strong performance at present.
