Topological Defect-Rich Carbon as a Metal-Free Cathode Catalyst for High-Performance Li-CO2 Batteries (Adv. Energy Mater. 30/2021)

Li–CO2 Batteries In article number 2101390, Dong Liu, Chuangang Hu, Liming Dai and co–workers develop topological defect–rich graphene based materials as high–performance metal–free cathodes in Li–CO2 batteries. The cathodes' sufficient and effective active sites for CO2 reduction/evolution facilitate the formation/decomposition of Li2CO3 during the discharging/charging process, resulting in unprecedented battery performance.
