Resolving the relationship between capacity/voltage decay and the phase transition by accelerating the layered to spinel transition

75% for the pristine material). These findings suggest that the capacity degradation and the voltage decay do not interact with each other and that the phase transition during cycling does not seem to negatively affect the voltage. This conclusion can also be extrapolated to other oxygen-reducing oxide systems to help understand the relationship between capacity and voltage decay. The modification is generalized and applicable to other cathode materials.
