Tesla unveils its LFP battery factory, claims it’s almost ready

Tesla has unveiled its lithium-iron-phosphate (LFP) battery cell factory in Nevada and claims that it is nearly ready to start production.

Like several other automakers using LFP cells, Tesla relies heavily on Chinese manufacturers for its battery cell supply.

Tesla’s cheapest electric vehicles all utilize LFP cells, and its entire range of energy storage products, Megapacks and Powerwalls, also employ the more affordable LFP cell chemistry from Chinese manufacturers.

This reliance on Chinese manufacturers is less than ideal and particularly complicated for US automakers and battery pack manufacturers like Tesla, amid an ongoing trade war between the US and virtually the entire world, including China.

As of last year, a 25% tariff already applied to battery cells from China, but this increased to more than 80% under Trump before he paused some tariffs on China. It remains unclear where they will end up by the time negotiations are complete and the trade war is resolved, but many expect it to be higher.

Prior to Trump taking power, Tesla had already planned to build a small LFP battery factory in the US to avoid the 25% tariffs.

The automaker had secured older manufacturing equipment from one of its battery cell suppliers, CATL, and planned to deploy it in the US for small-scale production.

Tesla has now released new images of the factory in Nevada and claimed that it is “nearing completion”:

Here are a few images from inside the factory (via Tesla):

Previous reporting stated that Tesla aims to produce about 10 GWh of LFP battery cells per year at the new factory.

The cells are expected to be used in Tesla’s Megapack, produced in the US. Tesla currently has a capacity to produce 40 GWh of Megapacks annually at its factory in California. The company is also working on a new Megapack factory in Texas.

Ford is also developing its own LFP battery cell factory in Michigan, but this facility is significantly larger, with a planned production capacity of 35 GWh.

Electrek’s Take

It’s nice to see this in the US. LFP was a US/Canada invention, with Arumugam Manthiram and John B. Goodenough doing much of the early work, and researchers in Quebec making several contributions to help with commercialization.

But China saw the potential early and invested heavily in volume manufacturing of LFP cells and it now dominates the market.

Tesla is now producing most of its vehicles with LFP cells and all its stationary energy storage products.

It makes sense to invest in your own production. However, Tesla is unlikely to catch up to BYD and CATL, which dominate LFP cell production.

The move will help Tesla avoid tariffs on a small percentage of its Megapacks produced in the US. Ford’s effort is more ambitious.

It’s worth noting that both Ford’s and Tesla’s LFP plants were planned before Trump’s tariffs, which have had limited success in bringing manufacturing back to the US.
