Voltage estimation of layered cathode materials LiMO2 (M=Al, Mn, Co, Ni, Cu, Zn) for lithium-ion batteries by using Compton profiles
Electronic structures were calculated by CRYSTAL14 code for the layered cathode materials LiMO2 (M=Al, Mn, Co, Ni, Cu, Zn). Mülliken population and Compton profile analysis showed that the redox orbitals are dominated by the O 2p states. The voltages of the redox reaction for LixMO2 were estimated f...

| Summary: | Electronic structures were calculated by CRYSTAL14 code for the layered cathode materials LiMO2 (M=Al, Mn, Co, Ni, Cu, Zn). Mülliken population and Compton profile analysis showed that the redox orbitals are dominated by the O 2p states. The voltages of the redox reaction for LixMO2 were estimated from the analysis of the calculated Compton profiles. The estimated voltages agreed with the previous report. This study shows that Compton profile measurement can be a new nondestructive testing tool for the measurement of the local voltage in a lithium-ion battery. |
