TL;DR: In this paper, a new approach is proposed to reclaim the graphitic anode materials from spent lithium ion batteries in electric vehicles, which involves a facile water treatment, which removes most of these impurities, opens Li+ transport channel and restores the graphite to be electrochemically active.

TL;DR: In this paper, a method for simply and efficiently preparing reduced graphene oxide by recycling graphite cathode material from powerbatteries is presented, which includes the following steps of detaching cathode pieces from the waste lithium ion batteries, soaking by water, separating graphite and copper foil collectors,replacing water for multiple times, filtering, drying, grinding, and screening, so as to obtain the recycled graphite oxide material.

TL;DR: In this article, a simple and efficient recovery method comprises the following steps of dismantling a cathode plate from the battery, mechanically crushing the cathode plates into flakes, putting the plate flakes in a sintering furnace at a protection atmosphere, performing heat insulation for 2h at 350-450 DEG C, and simply separating aluminum foil from the cathodes material, and performing refining treatment on the recovered cathode material.

TL;DR: In this paper, a graphite anode was removed from a waste lithium ion battery, soaking the anode electrode piece in water, and then separating the graphite from a copper foil current collector, and filtering, drying, grinding and sieving by meshes after changing water for multiple times.
