LMO 分解
Application ID: 129721
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a chemical reaction driven by protons that originate from solvent oxidation and water. The reaction decreases the electrode volume fraction.
This example models the capacity fade of an LMO vs lithium-foil cell. Results show a drop in both capacity and electrolyte salt concentration for abusive cycling conditions.
