What it is
Lithium is the lightest metal — used in lithium-ion battery cathodes and electrolytes, in glass and ceramics, and in greases. Two production routes dominate: hard-rock spodumene (mostly Australian), which is crushed, roasted and chemically converted; and brine, pumped from salt flats in the Andes and concentrated by 12–24 months of solar evaporation. Both feed a refining stage — almost all of it in China — that turns the raw material into battery-grade lithium carbonate or hydroxide.
Why it matters
EV and grid-storage demand is set to grow roughly ten-fold by 2035. Australia and Chile lead mining; China dominates refining. Without lithium there is no lithium-ion battery, and without lithium-ion batteries there is no serious electrification of transport or grid storage. Every gigafactory announcement, every EV mandate, and every grid-storage tender ultimately draws on the same finite carbonate and hydroxide flows.
Where it comes from
Hard-rock spodumene, shipped to China for refining.
Salar brine evaporation in the Atacama.
Mined output plus dominant refining capacity (~65% global).
Brine, scaling fast across the lithium triangle.
Brazil, Zimbabwe, Portugal, Canada.
What it is used for
Circular challenges
Whether lithium re-enters the economy at end-of-life is mostly decided at the design stage of the battery pack. These are the recurring blockers.
Recyclers wait for feedstock
Most batteries from EVs sold today will not reach recyclers until the 2030s — capacity is being built ahead of supply.
Cathode-to-cathode is the prize
Recovering lithium back into battery-grade cathode material is far more valuable than downcycling to industrial lithium carbonate.
Pack design matters
Glued, welded, and cell-to-pack designs make disassembly slow and expensive — design choices made today set recycling economics in the 2030s.
Recycling status
Global end-of-life recycling rate for lithium is still below 1%. The gap is not a technology problem — hydrometallurgical routes recover >90% of lithium from black mass — but a feedstock and economics problem. Most EV packs sold in the last decade are still on the road, so recyclers are scaling ahead of scrap. Under the EU Battery Regulation, recycled-content minimums for lithium kick in at 6% (2031) and 12% (2036), with 50% collection and 70% recycling efficiency targets by 2027 and 2031 respectively.
Demand trajectory
- 2015
Global demand ~180 kt LCE. EVs a rounding error in most car markets.
- 2020
Demand doubles to ~350 kt LCE as EV sales cross 3 million units.
- 2024
~1.1 Mt LCE consumed. Prices crash 80% from 2022 peak on new brine and spodumene supply.
- 2030
IEA projects 2.5–3.0 Mt LCE demand under stated policies; ~4 Mt under net-zero.
- 2035
Recycled lithium could cover 10–25% of demand — only if collection and cathode-to-cathode capacity scale now.
Policy angle
Lithium is designated Strategic under the EU Critical Raw Materials Act (Regulation (EU) 2024/1252). The Act sets 2030 benchmarks of 10% extracted, 40% processed, and 25% recycled from within the EU — with no single third country supplying more than 65% of any strategic raw material at any stage of processing.
