- bryanlarsen 4y agoAnd lithium batteries have a 3 decade history of 80% price reductions per decade.
- ClumsyPilot 4y agoHow many decades untill it is affordable as backup storage for a country?

- 988747 4y agoThere's not enough lithium on planet Earth even for all the electric cars we'll need, don't even start on using lithium batteries for large-scale storage. The only hope here is that Magnesium-based batteries will become a thing. EDIT: OK, it seems that I mistook the "mineable lithium deposits" number for the whole lithium available :) Anyway, unless there is a major technological breakthrough we are looking at few decades of lithium shortages. I expect countries to actually fight wars over lithium they way the US used to fight over oil. So, in the end, building nuclear plants seems more reasonable than building solar and then praying for cheaper batteries.
- lazide 4y agodoubts Lithium is roughly 0.002–0.006 wt% of the earths crust (concentrated in brines to much higher levels of course). It's no Iron (5% of the earths crust), but it is widely prevalent, and at #33ish most common elements on Earth, it's more about proving reserves of what used to be a niche material, than ACTUAL rarity. Nickel, Zinc, Copper are #23, 24 and #25 for instance, and lead is #36. We have no shortage of Lead, but mostly because it is a byproduct of Silver mining. It's typical for lead to go for $1/lb.
- S201 4y agoSo that means the price reductions will continue at that same rate? Extrapolation of a trend is not a forgone conclusion with anything. In fact, the price of lithium has gone UP in the past two years. Batteries may very well not be getting cheaper for the foreseeable future.
