Electrochemically Induced 2H→1T Interfacial Transformation Improves Charge-Transfer Kinetics in LiFe0.6Mn0.4PO4 Cathodes.
Polyanion cathodes such as LiFe1- xMnxPO4 (LFMP) offer structural stability and thermal safety but are often limited by sluggish interfacial charge transfer and progressive Mn-related degradation. Here, we report an electrochemically induced interfacial phase transformation in which a surface 2H-MoSx layer is converted...
