چکیده
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 batteries. The cathodes' sufficient effective active sites for CO2 reduction/evolution facilitate the formation/decomposition of Li2CO3 during discharging/charging process, resulting unprecedented battery performance.
