Resource Constraints for Lead -Acid Batteries in the near-term

There seems to be good resources ultimately available, around 1.5 bn tons according to one source, although I would like to see more sources on that:

However, it appears that in the West over 80% of our use is from recycling old batteries, and even given some improvement in resource use by Firefly technology and others, that will hardly allow us to move beyond using batteries just to fire up a car to running either an all-electric vehicle or hybrid on them.

Most new production these days is used by places like China and India, and they have a much smaller base to re-cycle, as industrialisation is recent.

To sum up, even if we have enough resources to switch to a lead-acid battery vehicle technology eventually, we could not ramp up fast enough to supply the need for hybrid or EV batteries anytime soon, hence an easy switch to electric using this well-developed technology does not appear possible in the near future.
