Abstract

Li ion battery (LIB) waste is an emerging environmental issue. Here we show that a typical LIB cathode material such as nickel manganese cobalt (NMC) oxide can be recovered and used directly as an electrocatalyst for the oxygen evolution reaction (OER). However, the impact of battery history indicates some decrease in OER performance.
