[Autohome?Industry]?Recently, we learned from relevant channels that Hirokazu Umeda, Chief Financial Officer of Panasonic Corporation of Japan, pointed out at the company’s briefing on Thursday that Panasonic Group of Japan is preparing to Produces 4680 batteries for Tesla. After Tesla’s “Battery Day” event, Panasonic began research and development for a prototype production line for 4680 batteries. Tesla’s new power battery is called Wujier 4680 battery. According to reports, while the production cost of the new 4680 battery is reduced, the energy density of the battery is increased by five times compared with previous power batteries, and the battery life performance is improved by nearly 16%. However, Tesla CEO Musk also admitted that the design and manufacturing process of the new battery is not yet fully mature, and it will take some time before it is fully put into production. However, Panasonic said: "Panasonic has considerable knowledge of this battery. It started this work immediately after Tesla Battery Day, and is also preparing to establish a parallel prototype production line." It is understood that this parallel prototype The production line will be located at the battery factory "Gigafactory 1" in Nevada, USA. The factory currently has 13 production lines. After the production line is put into operation, it will increase its production capacity by 10% to 39GWh per year.
Editor’s comment: For electric vehicles, the power battery is the basis for the survival of every pure electric vehicle. It has ultra-long battery life, perfect power response and suitable power storage capacity, which are all It is necessary to deepen research on battery technology. Tesla's latest 4680 battery cell has a larger appearance size and uses a highly innovative poleless lug design. This also has certain requirements in terms of battery production and speed. Panasonic can provide it in a short time. Tesla's development of a prototype production line shows that Panasonic is very optimistic about the future of 4680 batteries.
