Priority supply for Tesla Panasonic began trial production of 4680 batteries this year

Recently, Panasonic Chief Financial Officer Hirokazu Umeda said they are renovating some facilities and expect to start trial production of 4680 electric vehicle batteries at an undisclosed location in Japan at the beginning of the fiscal year that begins in April. The company then plans to conduct further trial production in Wakayama Prefecture, near Panasonic Osaka headquarters, although the time and location for official mass production have not yet been determined.

Tesla officially announced the 4680 battery cell in September 2021, claiming that the single energy is increased by 5 times, the vehicle mileage is increased by 16%, the power is increased by 6 times compared with the polar ear battery, and the power output is increased by 6 times. This revolutionary "battery cell" has triggered a hot discussion in the industry as soon as it was unveiled, which can not only increase the mileage by 16%, but also save 86% of the cost, which will make Tesla's new car have a more affordable price, and everyone has been looking forward to the listing of the 4680 battery cell model. Compared with the previous 21700 battery, the 4680 battery has a wider diameter and higher height, consisting of only 950 cells and an energy density of about 300kWh/kg. At the same time, the 4680 battery also uses laser electrodeless ear technology to remove the main heating components of the battery, the internal resistance is reduced, and the thermal stability and controllability of the battery are higher.
