Panasonic to boost Japan plant

...Looks to produce Tesla advanced format batteries


Panasonic Corp may upgrade one of its battery plants in Japan to produce advanced-format battery cells, a source told Reuters on Thursday.

Panasonic is currently the exclusive battery cell supplier for Tesla, and according to the source, the advanced battery cells are for Tesla, if needed by the U.S. electric vehicle (EV) maker,

Panasonic has a plant jointly owned by Tesla known as Gigafactory in the U.S. state of Nevada, as well as at two plants in Japan.

The Japanese plants handle cylindrical lithium-ion “18650” cells, used to power Tesla’s Model S and Model X vehicles, whereas the Nevada plant produces the newer, higher-energy density “2170” cells for the mass-market Model 3 sedan.

The Japanese production lines would only need minor changes to switch to 2170 cells from the 18650, said the person, who declined to be identified as the matter was private.

Japan’s Nikkan Kogyo newspaper reported on Wednesday that the upgrade could take place in this financial year ending March 2020.

Panasonic in a statement said nothing has been decided.

The development comes after Tesla Chief Executive Elon Musk said Panasonic had been “a constraint on Model 3 output since July”. Panasonic’s Nevada output is 24 gigawatt-hours (GWh), Musk tweeted this month, as opposed to the planned 35 GWh capacity.

Panasonic said it had completed installation of its equipment for a Nevada capacity of 35 GWh by the end of March 2019, but that not all the installed equipment is in full operation.
