I want to underline, it's not about any other chemistry overtaking lithium he is talking.

Lithium will almost certainly remain the one, and only mainstream battery chemistry simply because of physics. Lithium ion has the lowest mass per unit of charge.

It's about cathodes, and electrodes which may change, as well as their manufacturing technology.

There's an element above lithium on the periodic table that has an even lower mass per unit of charge. Weird that no one talks about this. Also repeating what I said elsewhere:

> It's bizarre how people refuse to accept that hydrogen fuel cells are technically batteries and have absurdly high energy densities. And if pressed, you usually hear some excuse like poor efficiencies, as if that isn't a powerful justification for pouring billions of dollars into the problem.
