This is the physical quantity of battery output, in terms of kWh or number of batteries, probably with some weighting to correlate lithium ion to, say, lead acid batteries (though these days this output is nearly only lithium ion, I would guess).

To truly understand what's going on, there are two other series needed which are linked in the related series:

- Producers' price index, how much the manufacturers are charging per unit of batteries https://fred.stlouisfed.org/series/PCU335911335911

- Value (in $) of shipped batteries (roughly price * volume): https://fred.stlouisfed.org/series/A35DVS (thanks for the correction, laser!)

Also note that the time scale for all three are different, as they apparently started recording these at different times.

FRED data is super useful for a high level view of what's going on in various industries, I highly recommend playing with it if you're ever looking at investing or other spaces to work in!

Most of the US' capacity is a partnership with foreign firms (LG, Panasonic, SK On), so why not put an asterisk on that as well?

This is why you can't build anything in America anymore.

Recycling is so effective that with the little that we're currently doing (not enough batteries to recycle yet), we get more battery out of the recycling process than what went in. Because the battery manufacturing is improving and getting more kWh out of the same input materials than when the battery was originally made, and the difference is bigger than anything lost to the recycling process.

Batteries and renewable energy generation are not like building an economy on fossil fuels, which is a very fragile economy vulnerable to massive spikes in input costs. Batteries and renewable energy are fundamentally anti-inflation devices.

Batteries don't have rare-earth materials in them. Lithium, nickel, and iron are very plentiful in the US. The "rarest" of materials that might be mined is Cobalt. That, however isn't because it's a hard to find. Rather, cobalt has basically no industrial applications outside of battery production. And, importantly, not all battery chemistries require cobalt, just the nickel manganese cobalt batteries.

Idaho has a cobalt mine that's not currently in operation. The reason is because demand is super low and the artisanal mines in africa are cheaper than spinning up a full industrial mine.
