Graphite recycling from spent lithium-ion batteries

Depending on the purity of products requirements, there are two general methods for recycling the spent graphite in the pretreatment stage: direct crushing and artificial splitting. Then, graphite must be separated from the broken battery materials or copper foil. [pdf]

Lithium ion battery recycling rate

Lithium-ion batteries are widely used in various devices, but their recycling rate is still low at under 5%1. The main reasons for this are cost and the complexity of recycling methods1. Recycling processes today recover approximately 25% to 96% of the materials of a lithium-ion battery cell2. Three major methods are used to recycle lithium-ion batteries: direct recycling, pyrometallurgy, and hydrometallurgy1. [pdf]
