I think there are ~3 major battery improvements to watch out for.
1. Solid state batteries. Likely to be expensive, but promise better energy density.
2. Some really good grid storage battery. Likely made with iron or molten salt or something like that. Dirt cheap, but horrible energy density.
3. Continued Lithium ion battery improvements, e.g. cheaper, more durable etc.
- Animats 2y agoThere are now a few large flow batteries. Here's one that's 400 megawatt-hours.[1] Round trip efficiency is poor and the installation is bulky, but storage is just tanks of liquid that are constantly recycled.

- davedx 2y agoMy money is on saltwater batteries. You can make them really cheaply. Flow batteries are still too complicated IMO.
