The world we live in today runs on batteries. But the lithium ion batteries that dominate the market are expensive and environmentally demanding to extract. The raw materials for lithium ion batteries are scarce and concentrated in a few geographical regions. This places continued pressure on supply chains.
The nice thing about batteries is that they can be recycled almost entirely in a closed loop cycle, so eventually we’ll reach a place where new batteries aren’t mined at all, but recycled from old
Idk how far into that we are currently, however there are recycling facilities kinda all over especially for ev batteries. They can also be reused for a while for other things, like home energy storage (like in place of a whole-house generator for blackouts if you are grid-tied, or solar storage for off-grid)
