Abstract:
A composite cathode is provided which includes a collector, an active cathode material, a binder, a solid inorganic lithium-ion conductor and a liquid electrolyte. The solid inorganic lithium ion conductor is present in the composite cathode in a higher volume and weight proportion than the liquid electrolyte. A method for forming the composite cathode is also provided, and a lithium ion battery is provided which includes a composite cathode having a collector, an active cathode material, a binder, a solid inorganic lithium ion conductor and a liquid electrolyte.
