Recycling spent LiNi1−x−yCoxMnyO2 cathodes to efficient catalysts for the oxygen evolution reaction

This work develops a green strategy to recycle spent LiNi 1− x − y Co x Mn y O 2 cathodes to hydroxide catalysts for the OER. The performance of hydroxides with various compositions is compared and the one made from LiNi 0.33 Co 0.33 Mn 0.33 O 2 shows superior properties.
