Abstract
Methods and systems are provided for a cathode material for lithium ion batteries. In one example, the cathode material may include a lithium mixed metal oxide core and a surface coating surrounding the core. Optionally, a passivating layer may continuously surround the surface coating. In some examples, the surface coating or surface layer may include a sacrificial lithium source, a lithium-based active cathode catalyst, or a combination thereof. In other examples, methods are provided for manufacturing the cathode material for use in a lithium ion battery.
