ALL-SOLID-STATE BATTERY

PROBLEM TO BE SOLVED: To provide an all-solid-state battery, capable of preventing a battery from being deteriorated by preventing moisture (water vapor) from entering from the outside and also capable of exhibiting original charge and discharge characteristics by suppressing the inhibition of expansion/contraction of an all-solid-state battery electrode and suppressing a reaction between a glass layer and a battery element.SOLUTION: In an all-solid-state battery, a buffer layer is provided so as to cover a battery element including a positive electrode, a negative electrode and a solid electrolyte, and a glass layer is provided around the buffer layer covering a periphery of the battery element. By the configuration of the glass layer, an electrode can be expanded and contracted, and by suppressing a reaction between the glass layer and the battery element, the battery element can maintain long-term charge/discharge performance.SELECTED DRAWING: Figure 1 【課題】外部からの水分（水蒸気）侵入を防いで電池の劣化防止が可能で、かつ全固体電池の電極の膨張収縮の阻害を抑制しまたガラス層と電池要素との反応を抑制することにより、本来の充放電特性を発揮することが可能な、全固体電池を提供する。【解決手段】正極と負極と固体電解質とを含む電池要素を覆うように緩衝層を設ける。また、該電池要素の周囲を覆う緩衝層の周りにガラス層を設ける。このガラス層の構成により、電極の膨張収縮を可能にしまたガラス層と電池要素との反応を抑制することにより、該電池要素の長期間充放電性能を維持できる。【選択図】図１
