▎ 摘　　要

NOVELTY - An electrochemical battery cell comprises an anode having a primary anode active material, a cathode having a primary cathode active material, and an ion-conducting electrolyte in ionic contact with anode and cathode. The primary anode active material is chosen from lithium, sodium, potassium, magnesium, aluminum, zinc, titanium, manganese, iron, vanadium, cobalt and/or nickel. The primary cathode active material is chosen from metal oxide, metal phosphate, metal sulfide, or metal or semi-metal different than primary anode active material. The metal or semi-metal in cathode is selected from tin, bismuth, antimony, indium, tellurium, phosphor, magnesium, aluminum, zinc, titanium, manganese, iron, vanadium, cobalt, nickel and/or selenium. USE - Electrochemical battery cell for electronic device (claimed). ADVANTAGE - The battery cell supplies external circuit with output voltage of 0.3-0.8 V without using voltage regulator. DETAILED DESCRIPTION - An electrochemical battery cell comprises an anode having a primary anode active material, a cathode having a primary cathode active material, and an ion-conducting electrolyte in ionic contact with anode and cathode. The cell has an initial output voltage (Vne foam in both the anode and the cathode and the lack of Cu foil and Al foil current collectors also enables the production of flexible battery cell for use in a wireless, wearable, or implanted device that can be of an odd shape. The cellular structure in a polymer matrix is typically created for the purpose of reducing density, increasing thermal resistance and acoustic insulation, while increasing the thickness and relative stiffness of the original polymer. With some heat treatment at 150 C., the dried GO compact exhibits the formation of a hump centered at 22 , indicating that it has begun the process of decreasing the inter-graphene spacing due to the beginning of chemical linking and ordering processmeasured at 10% depth of discharge (DoD) from a lower limit of 0.3 V to an upper limit of 0.8 V, and a final output voltage Vf measured at DoD of 90% or less. The voltage variation measured as ratio of difference of voltages (Vi) and (Vf) and voltage (Vi) is plus minus10% or less, and the specific capacity between voltages (Vi) and (Vf) is no less than 100 mAh/g or 200 mAh/cm3 based on the cathode active material weight or volume. The primary anode active material is chosen from lithium, sodium, potassium, magnesium, aluminum, zinc, titanium, manganese, iron, vanadium, cobalt and/or nickel. The primary cathode active material is chosen from metal oxide, metal phosphate, metal sulfide, or metal or semi-metal different than primary anode active material. The metal or semi-metal in cathode is selected from tin, bismuth, antimony, indium, tellurium, phosphor, magnesium, aluminum, zinc, titanium, manganese, iron, vanadium, cobalt, nickel and/or selenium. An INDEPENDENT CLAIM is included for electronic device.
