NOVELTY - An all-solid secondary battery (100) comprises positive electrode (110) comprising positive electrode active material layer (112), negative electrode (120) comprising negative electrode current collector (121), and negative electrode active layer on negative electrode collector and solid electrolyte layer between positive and negative electrodes active material layers. The negative electrode layer comprises first particles comprising carbon material, and second particles comprises metallic material that does not alloy with lithium metal. USE - All-solid secondary battery. ADVANTAGE - The all-solid secondary battery uses lithium as a negative electrode active material and has improved characteristics. The lithium dendrite is prevented from growing in a branched shape, and the capacity degradation is prevented. The negative electrode current collector, the area between the current collector and the active material layer do not include lithium metal after the discharging of the battery, and thus the characteristics of the negative electrode are improved. The capacity degradation due to the lithium metal dendrites is prevented, and an increase in the capacity of the solid electrolyte is prevented and a short circuit in the battery is prevented due to a lithium metal-dendrite. The performance of the positive electrode is improved and the charging and discharging characteristics are improved, and capacity degradation caused by the lithium is prevented or reduced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method of charging an all-solid secondary battery, which involves charging the all-solid secondary battery to a voltage such that an initial charge capacity of the negative electrode active material layer during charge of the all-solid secondary battery is exceeded; (2) a method of operating the all-solid secondary battery, which involves charging the all-solid secondary battery, where prior to the charging of the all-solid secondary battery, the negative electrode current collector, the negative electrode active material layer, and an area between the negative electrode current collector and the negative electrode active material layer do not comprise lithium metal; (3) a method of manufacturing an all-solid secondary battery, which involves obtaining a positive electrode comprising a positive electrode active material layer, obtaining a negative electrode comprising a negative electrode current collector, and a negative electrode active material layer on the negative electrode current collector and providing a solid electrolyte layer between the positive electrode active material layer and the negative electrode active material layer, where the negative electrode active material layer comprises first particles comprising a carbon material, and second particles comprising a metallic material that does not alloy with lithium metal.
