Tesla, Panasonic Officially Partner Up for Gigafactory

The two companies have worked together for many years on electric vehicles, but this new deal takes the partnership to a whole new level.

The basic gist, since the agreement itself has not been released, is that Tesla will take care of the exterior (the "land, buildings and utilities") while Panasonic will pay for the machines inside in order to, "manufacture and supply cylindrical lithium-ion cells" that Tesla will then use to, you know, build battery packs. Panasonic's machines will take up half the space while a network of as-yet unnamed suppliers will be involved in the other half, according to the press release announcing the deal. Read it below.

There's been lots of speculation as to where the Gigafactory will be built, but the exact location probably won't be revealed until later this year, so don't expect any battery packs from the Gigafactory to be coming any time soon. That's why Panasonic is still going to be building Tesla cells in Japan for the time being.

As previously announced, the Gigafactory is expected to make batteries for around 500,000 EVs a year as well as more for stationary storage needs. That means 35 GWh worth of cells and 50 GWh worth of packs each year by 2020. We expect more information to trickle out today along with Tesla's quarterly earnings.
