  • ABUSE-TOLERANT LITHIUM ION BATTERY CATHODE BLENDS WITH SYMBIOTIC POWER PERFORMANCE BENEFITS
    Publication number: 20250246603
    Abstract: Methods and systems are provided for a blend of cathode active materials. In one example, the blend of cathode active materials provides a high power battery with low direct current resistance while improving lithium ion cell safety performance. Methods and systems are further provided for fabricating the cathode active material blend and a battery including the blend.
    Type: Application

  • Method and systems for coated cathode materials and use of coated cathode materials
    Patent number: 12362354
    Abstract: A coated cathode material for lithium-ion batteries is disclosed. Methods and systems are further provided for applying a coating to an active cathode material for use in a lithium-ion battery. In one example, the coated cathode material may include a high-nickel content active cathode material, such as lithium nickel manganese cobalt oxide or lithium nickel aluminum cobalt oxide, coated with a coating including one or more high energy density active materials, such as lithium vanadium fluorophosphate and/or a lithium iron manganese phosphate compound. In some examples, the high-nickel content active cathode material may include greater than or equal to 60% nickel content.
