  • Hybrid lithium-ion battery-capacitor (H-LIBC) energy storage devices
    Patent number: 11901122
    Abstract: A hybrid lithium-ion battery-capacitor (H-LIBC) energy storage device includes a hybrid composite cathode electrode having a lithium ion battery (LIB) cathode active material and a lithium ion capacitor (LIC) cathode active material. An anode electrode having a surface is pre-loaded and pressed with a lithium (Li) thin film source. The anode electrode is pre-lithiated with the lithium film source by positioning the Li film source on the surface of anode electrode after electrolyte filling and soaking processes, a separator and an organic solvent electrolytic solution including a lithium salt electrolyte are also provided. A method of making a hybrid lithium-ion battery-capacitor and a method of making a hybrid composite cathode for a hybrid lithium-ion battery-capacitor are also disclosed.
    Type: Grant
