Signal · Where battery-grade lithium comes fromPrepared for Albemarle · September 2026
The competition for your tonne is not ExxonMobil. It is the recyclers you did not mention on the call.
You submitted the Atacama permit in March for up to six trains and told the market you had evaluated dozens of extraction technologies. Europe requires 50% of lithium to be recovered from waste batteries by the end of 2027 and 80% by the end of 2031 — the recycled tonne arrives on a legal timetable. This is every source of battery-grade lithium on one chart.
Global patent families across 14 lithium routes — extraction and recovery
The decision
Atacama expansion · up to six trains · permit filed March 2026
The clock
EU battery law: 50% recovered by end-2027 · 80% by end-2031
The map
Fourteen sources of battery-grade lithium, measured on maturity and improvement rate.
The maturity split is TRL 5, the end of validation in a relevant environment; the high/low bands split on the median improvement rate of these fourteen routes. The improvement-rate axis is non-linear (30–360%/yr). Source: GetFocus lithium analysis · September 2026.
What the signal shows
The other supply4× vs 2017
Recycling is improving four times faster than your route.
In 2017 recycling improved about twice as fast as brine. Today it is four times — the gap has widened every year. The fastest route on the whole chart is one the recyclers already run at full size.
The 2025 headline−50% since 2017
Last year's front-runner is going backwards.
Graphene-oxide composites, the 2025 front-runner, have halved since 2017 — graphene-oxide membranes are down too. They are the only two routes going down. Metal-organic frameworks doubled in the same time: of the two you were told to watch, only one held up.
Where you sit3× since 2017
Your own route is fine — and it is the slow half of the chart.
Your aluminium sorbents keep improving, but all seven brine routes improve at close to the same speed — the choice between them barely matters. One recycling route runs your kind of sorbent inside a recycling plant: tripled since 2017. Your know-how, someone else’s feedstock.
Who holds the patents
Patent families per route — and each route’s biggest holder.

Your LDH sorbent route is the orange bar: 6,775 families, by far the most crowded route on the chart — and the one improving at 40%/yr. The recovery routes carry fewer families but are moving three to four times faster: hydrometallurgy 2,698 at 161%/yr, lithium-first recovery 1,609 at 132%/yr. Volume and speed point in opposite directions.
For Albemarle
The Atacama capital call still looks right: your sorbent family keeps improving and no rival brine route is pulling away. The exposure is on the other side of the chart — recycled lithium and mined lithium compete for the same tonne, recycling is improving far faster, and Europe has put a date on it. The opening: the fastest-growing recycling route pulls lithium out first with selective sorbents — the chemistry you have spent ten years on.
The method, in one minute
What is TIR?
TIR — the Technology Improvement Rate — measures how fast a technology gets better each year, computed from global patent data. Not who is filing, or how much: how fast the route is actually moving. Historically, the fastest-improving technology always wins.
