Abstract
Provided is a method for recycling a battery electrode by immersing the electrode into a delamination solution and subsequently precipitating a polymeric binder with the addition of a precipitation agent; wherein the electrode comprises a current collector and an electrode layer material coated on one side or both sides of the current collector; wherein the electrode layer material comprises a polymeric binder; and wherein the polymeric binder comprises a copolymer comprising a structural unit derived from an acid group-containing monomer and a structural unit derived from a hydrogen bond-forming group-containing monomer (ii). The method disclosed herein circumvents complex separation process, corrosion of current collector and contamination of polymeric binder, enables excellent materials recovery and allows the recycling of battery electrode to be achieved in a highly efficient manner.
