Greener/ more efficient battery recycling uses molten salt to directly restore structure/ performance of used high-nickel cathode materials
https://www.eurekalert.org/news-releases/1104099 "restores original cathode material for reuse... ternary molten salt (heated: lithium hydroxide, lithium nitrate, lithium salicylate)... high-nickel NCM811 loses lithium/ develops structural defects, restored moving lithium ions into damaged material/ reorganizes atoms to original ordered layered structure/ unwanted surface rock salt layer removed... achieves 196 mAh/g initial discharge capacity, maintains 76% of that capacity after 200 cycles... operates at relatively low temperatures, no: strong acids/ toxic solvents" Related: New recharge-to-recycle reactor turns battery waste into new lithium feedstock https://www.eurekalert.org/news-releases/1105397 How battery charging led to a breakthrough in lithium recycling https://newatlas.com/energy/battery-charging-lithium-recycling/ 3-in-1 process recycles spent lithium batteries, captures CO₂ and generates catalysts at room temperature https://techxplore.com/news/2026-01-recycles...
