▎ 摘　　要

NOVELTY - All-solid lithium secondary battery (10) comprises a positive active material layer (200), a negative active material layer (100), and a solid electrolyte layer (300) arranged between the positive active material layer and the negative active material layer, where the negative active material layer includes a carbon structure and silver nanoparticles. The carbon structure includes a structure in which a graphene sheets are connected to each other, and the graphene sheets include two or more graphene sheets having different surface directions. The silver nanoparticles are arranged on the surface of the carbon structure. USE - The battery is used in mobile devices and notebook computers, energy storage systems, electric vehicles, a power tool that moves under the power of an omniscient motor (power tool), hybrid electric vehicles, plug-in hybrid electric vehicles, electric two-wheeled vehicles including electric bicycles (E-bikes) and electric scooters (E-scooters), electric golf carts, and urban air mobility. ADVANTAGE - The battery has improved lifespan and safety. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing the all-solid lithium secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the all-solid-state lithium secondary battery. 10All-solid-state lithium secondary battery 100Negative active material layer 110Anode current collector 200Positive active material layer 300Solid electrolyte layer
