ALL-SOLID BATTERY

PROBLEM TO BE SOLVED: To provide an all-solid battery which enables the prevention of the degradation of a battery by preventing the penetration of moisture (water vapor) from the outside, and allows originally designed charge and discharge characteristics to be exhibited by suppressing the impediment to the expansion and shrinkage of all-solid battery's electrode and the reaction between a glass layer and a battery element.SOLUTION: An all-solid battery comprises: a battery element including a positive electrode, a negative electrode and a solid electrolyte; a buffer layer provided to cover the battery element; and a glass layer provided around the buffer layer covering the battery element. The electrodes are allowed to expand and shrink by forming the glass layer. By suppressing the reaction between the glass layer and the battery element, the charge and discharge performances of the battery element can be maintained over a long period of time. 【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
