▎ 摘  要

NOVELTY - The battery (10) comprises a cathode layer (100) including a cathode active material, an anode layer (200) having an anode current collector (201) and an anode active layer (202) arranged on the anode collector, and a solid electrolyte layer (300) arranged between the cathode material layer and the active layer. The active layer comprises an anode material and amorphous carbon, where the amorphous carbon comprises one of carbon black, acetylene black, furnace black, ketjen black or graphene and the anode active material comprises one of gold, platinum, palladium, silicon, silver, aluminum, bismuth, tin, titanium or zinc. The weight ratio of the active material to the carbon is 1:3-1:1. The anode has sheet resistance of 0.5 milliohms-centimeters. USE - All-solid-state secondary battery. ADVANTAGE - The all-solid-state secondary battery has high energy density, high capacity, and improved cycle characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing an all solid-state secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a schematic structure of an all-solid-state secondary battery.
