Abstract All‐solid‐state lithium‐ion batteries (ASSLIBs) are attracting significant attention due to their high energy density, conductivity and safety. However, they expected generate substantial waste in the near future, leading resource depletion environmental pollution. Therefore, it is crucial achieve green, mild safe recovery of ASSLIBs. Here, we for first time use green deep eutectic solvents (DESs) effectively recover solid‐state electrolytes (SSEs) from ASSLIBs at temperature. Results show that Li leaching efficiency can reach up 87.5 % with a superhigh Li/La selectivity 1902 low temperature 80 °C. Furthermore, 70 anti‐solvents screened recycle dissolved SSEs leachate 12 could precipitate room This research opens new possibilities recovering using sustainable, cost‐effective solvents.

Efficient and Green Recycling of Waste Lini1-X-Ycoxmnyo2 Cathodes to Nico2o4 Catalysts for Lithium-Oxygen Batteries

Published: Jan. 1, 2024

As the production and waste of lithium-ion batteries (LIB) continues to increase, extracting recovering precious metals through environmentally friendly solvent processes has become imperative. Deep eutectic solvents (DES) are innovative green with great potential for valuable metallic elements from LIBs. This study used choline chloride/oxalate dihydrate DES selectively separate yield nickel-cobalt-manganese (NCM) cathodes. Utilizing recovered nickel oxalate as a raw material, efficient catalyst NiCo2O4 could be synthesized again via simple hydrothermal method, which was subsequently applied in lithium-oxygen batteries. Electrochemical results show that battery assembled this an extremely low overvoltage 0.19V high specific capacity 32218 mAh g-1. It exhibits stable cycling 241 hours at current density 500 mA
