[Original by Dongchedi Industry] Recently, according to foreign media (electrek), Tesla has received 4680 battery samples from Panasonic. It is reported that Panasonic will start mass production of this new battery in 2023.
It is worth mentioning that about half a month ago, Tesla asked Panasonic to speed up the development of its 4680 battery unit to provide power for new cars mass-produced in 2023 such as Tesla's electric pickup truck Cybertruck.

According to Panasonic, the mass production of new batteries will begin on March 1, 2023. The initial production will be conducted at the Wakayama plant in Japan, where the company will fine-tune the process. Only after that production will be transferred to North America. Kazuo Tadanobu, CEO of Panasonic Energy, said: "It will be the first to establish the first test production line in Japan, making it possible to produce large-scale prototype batteries."

As early as the 2020 battery day, Tesla released the 4680 battery for the first time. Tesla CEO Musk once said on the spot that the poleless ear battery shortens the current movement path and reduces internal resistance, significantly reduces current deviation, and significantly improves its heat production and heat dissipation capabilities, which will help improve the cycle life of the battery.

Compared with the previous "1865" and "2179" batteries, the diameter of the new battery will double to become the new "4680 battery". The new battery's energy density can be increased by 5 times, its range can be increased by 16%, and its power can be increased by 6 times. Due to its higher battery capacity, the 4680 battery can effectively reduce the number of electric vehicle batteries installed, so the manufacturing cost is lower.
In February this year (February 19 local time), Tesla announced on its official account that its 4680 battery production at its Fremont plant in California: the production exceeded 1 million in January. This means that Tesla has made a major breakthrough in the technical barriers of 4680 batteries, and it also shows that Tesla has further moved from the large-scale mass production of 4680 batteries.
Recently, Panasonic is considering establishing a new battery factory in the United States to supply 4680 batteries for Tesla and possibly other electric car maker . The candidate locations are oklahoma and klahoma in the central and central U.S., and will start production as early as 2024, Panasonic plans to operate the factory independently.
