“Worldwide lithium resources identified by USGS started to increase in 2017 owing to continuing exploration. Identified resources in 2016, 2017, 2018, 2019 and 2020 were 41, 47, 54, 62 and 80 million tonnes, respectively.” https://en.wikipedia.org/wiki/Lithium#Reserves
There is little to suggest this trend will suddenly stop unless we simply stop looking. Further, a 5x increase in lithium has minimal impact on the long term EV or grid storage economics. That’s a lot of wiggle room for more expensive extraction.
That’s my point, resources are probable sources of economically extractable resources. It’s mostly a long term vs short term question, so limiting things to reserves vastly underestimates availability in 2040+.
Even resources is an underestimation as again it’s based on economic assumptions that are quite flexible. New technology for example can change what’s considered economically feasible.
