Mark can you substantiate that statement?

Nickel metal hydride?
There are actually lots of rechargeable battery technologies that could be
used. Each has different strengths and weaknesses.
It's unfortunate that manufacturers tend to prefer a monoculture. "One thing to rule
them all". But anything that you try to apply to 8 billion people is bound to cause
unforeseen problems. Different applications should really use different solutions.
Lead-acid is cheap, and widely recyclable. But it's relatively heavy and has a
low energy density. It still makes sense for short-range EVs like golf carts,
fork lifts, scooters, etc. Also, don't forget that virtually every ICE is still
using lead-acids.
Nickel-based batteries (nickel-iron, nickel-cadmium, nimh) have higher energy
density and longer life, and the materials are relatively abundant. Nickel is
expensive, but fairly easy to recycle (though it's not being widely done for
batteries).
Lithium-based batteries have the highest energy density, but are expensive,
less safe, and (at least for the present) not being recycled.
And, there are lots of other chemistries that could be used. We should be
exploring *every* option; not just blindly picking one.
