Abstract:
(EN) The objective of the invention is to improve the efficiency of producing an all-solid state battery. In this all-solid state battery, positive electrode tabs are joined to one another, negative electrode tabs are joined to one another, and two-sided positive electrodes and two-sided negative electrodes are layered alternately, thereby constituting electrical connections in parallel within a battery unit. A one-sided positive electrode and a one-sided negative electrode are formed at respective end portions in the layering direction of the battery unit. Among adjacent battery units, the positive electrode collector in the one-sided positive electrode of one of the battery units and the negative electrode collector in the one-sided negative electrode of the other battery unit are connected in the layering direction, thereby constituting electrical connections in series among a plurality of the battery units.
(FR) L’objectif de l’invention est d’améliorer l’efficacité de production d’une batterie entièrement solide. Dans cette batterie entièrement solide, des languettes d’électrode positive sont assemblées les unes aux autres, des languettes d’électrode négative sont assemblées les unes aux autres, et des électrodes positives bilatérales et des électrodes négatives bilatérales sont stratifiées en alternance, de façon à constituer des connexions électriques en parallèle dans une unité de batterie. Une électrode positive unilatérale et une électrode négative unilatérale sont formées au niveau de parties d’extrémité respectives dans la direction de stratification de l’unité de batterie. Parmi des unités de batterie adjacentes, le collecteur d’électrode positive dans l’électrode positive unilatérale de l’une des unités de batterie et le collecteur d’électrode négative dans l’électrode négative unilatérale de l’autre unité de batterie sont connectés dans la direction de stratification, de façon à constituer des connexions électriques en série entre une pluralité d’unités de batterie.
(JA) 全固体電池の生産性を向上させる。正極タブ同士および負極タブ同士が接合され、両面正極と両面負極とが交互に積層されて、電池ユニット中で電気的な並列接続が構成され、電池ユニットにおける積層方向の端部に片面正極と片面負極とが形成され、隣接する電池ユニットの一方の電池ユニットの片面正極における正極集電体および他方の電池ユニットの片面負極における負極集電体が積層方向で接続されることで、複数の電池ユニットは電気的な直列接続が構成される全固体電池。
