Method embodiments useful for recycling spent lithium-ion battery (LIB) electrodes to extract critical and/or valuable elements from LIBs are provided and involve mechanochemical processing of spent LIB electrodes in the presence of certain chemical agents to recover products that can include, but are not limited to, metallic solids such as elemental metals or metal alloys, and/or inorganic compounds, metal salts, or organometallic derivatives. The desired products can be separated from by-products and contaminants and further processed into LIB electrode materials or/and other substances.
A method for recycling spent LIB material, comprising subjecting the spent LIB material to mechanochemical processing by mechanical processing the spent LIB material in the presence of a metallic reducing agent to produce a recovered metal or metal alloy product.
A method for recycling spent LIB material, comprising subjecting the spent LIB material to mechanochemical processing by mechanical processing the spent LIB material in the presence of an organic chemical compound or a polymer having a functional moiety that reacts with at least one constituent of the LIB material to produce a water-soluble metal salt.
