Abstract

See full text

A doped cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for doping a cathode material for use in a lithium-ion battery. In one example, the doping may be a dry surface doping process. In some examples, dopants may stabilize a crystal structure of the cathode material and may result in fewer side reactions with an electrolyte as compared to an undoped cathode material. As such, cycling performance and capacity retention may be improved relative to the undoped cathode material. Further, in some examples, the doped cathode material produced with the dry surface doping process may have improved cycling performance and capacity retention relative to a comparable doped cathode material produced with a wet surface doping process.
