Summary: Li2MnO3, as a traditional member of lithium-rich layered cathodes, shows large specific capacity, but suffers from capacity fading and voltage decay. Iridium doping improves electrochemical performance, with dopant concentration and calcination temperature affecting the performance due to intrinsic microstructure and crystallization. The mechanism of improvement lies in the structure stability induced by iridium doping in TM sites, enhancing high-capacity cathode materials for lithium-ion batteries.
