Large-scale synthesis of LiMnO cathode materials a rheology-assisted solid-phase method using citric acid
Although they possess a high working voltage and environmental compatibility, and are low in cost with abundant resources, the poor cycling performance and rapid capacity attenuation of LiMn 2 O 4 cathodes at high temperature restrict their extensive application. In this study, LiMn 2 O 4 materials...
