Method for forming a Li-ion battery cell comprising an LNMO cathode material

A process forms a Li-ion battery cell including an LNMO-based cathode material, an anode material, a separator and an electrolyte. The process successively includes charging the cell until the cell reaches a state of charge of 100%, storing the cell in the state of charge of 100% in an open circuit...

Zusammenfassung:	A process forms a Li-ion battery cell including an LNMO-based cathode material, an anode material, a separator and an electrolyte. The process successively includes charging the cell until the cell reaches a state of charge of 100%, storing the cell in the state of charge of 100% in an open circuit for a period of time of at least 48 hours, and removing gas generated during the charging and the storage.
