Battery technology development is a huge field with a long record of failed promises (often related to issues like lifetime, flammability, manufacturing cost, etc.).
One interesting recent development is the replacement of the cobalt needed in lithium batteries with iron. Cobalt wars in Africa's Congo are a current issue:

Now it seems that cobalt can be replaced with iron with no efficieny/storage capacity losses:

Lithium itself doesn't really seem replaceable for where it's used, in applications that demand relatively high energy density and voltage.
- otherotherchris 5y agoThe world has a nearly infinite supply of lithium. Evaporating naturally occurring brine in poverty stricken shitholes is just a lazier way of extracting the tiny amount that we've used historically rather than capital intensive extraction from spodumene, clay, and geothermal or desalination wastewater.

- bdamm 5y agoConveniently, lithium is also abundant and can be mined from many different sources, including the ocean. So wars over lithium seem unlikely, and lithium shortages also seem unlikely since the main constraint is over scaling up efficient mining.
- imtringued 5y agoI hope that lithium recycling is going to be more cost effective than extracting new lithium. In theory it should be a very straightforward process compared to mining.
