Dimensionally stable vitreuos oxide intercalation cathodes for Li-batteries
Many of the crystalline oxide intercalation cathodes go through one or more phase transitions until they are completely discharged. In secondary batteries repetitive phase transitions during cycling cause problems. Apart from fatal irreversible transitions, e.g. due to overdischarge, ever highly reversible phase transitions are undesired, because they are related with dimensional changes and strains and — in the long run — may result in a “powderisation” of the cathode material.
