Panasonic confirms it will produce 4680 cells Tesla in Japan


Panasonic has officially made its large-format cylindrical cells pending — the 4680 format that Tesla championed in 2020 Battery day.

“Panasonic is developing a new high-capacity lithium-ion battery, “4680”, at multiple locations inside Japan,” the company said in a press release released Monday. The statement clearly underlines the level of R&D the battery supplier has done on the cells. “The company will gradually develop its manufacturing capabilities in preparation for the full rollout.”

The company, which is often ranked as the third-largest supplier of EV batteries in the world by production capacity, said that it will establish a battery production facility at its Wakayama plant in western Japan. Meanwhile, development continues on the new umbrella format at “multiple locations inside Japan,” the company said, with mass production set to begin in the fiscal year ending March 2020. 2024.

The 4680 format — 46 mm diameter x 80 mm long — promises five times more power than smaller cylindrical cells. Mathematically, they take up about 5.7 times more volume than the 2170 format used in Tesla vehicles, as well as those from Lucid and Rivian. The biggest advantage of the new format is that it can allow for more cellular energy to be produced, with a lower amount of raw materials — and, Tesla’s Musk teased on Battery Day 2020, the possibility of halving overall cell cost over time.

This announcement follows reports going back to October, when the electronics giant and key supplier of Tesla reveal a prototype version of the cell. In November, the CEO of the company’s battery division, Kazuo Tadanobu, told Nikkei Asia that although the technological goals for the cells had been “largely achieved”, mass production of the cells had been achieved. would require “new technology”.

The growth and enhancement from Panasonic underscores the battery supplier’s special relationship with Tesla. In April 2021, Panasonic EV battery boss unconvinced by Tesla’s mobile format; He told Bloomberg that larger cells are harder to manufacture, more prone to overheating and more susceptible to particle contamination.

But with competitors like Samsung SDI and LG Energy Solution compete to create new cellsperhaps the bottom line has helped change the position of the main supplier.

Tesla has also production of cells, it is intended for use in Texas-built Model Y vehicles. It recently confirmed that it produced one million of the 4680 cells in January, at its test manufacturing facility in California — enough cells for more than 1,000 Model Ys.
