Method for producing electrical energy store and electrical energy store

A method for producing an electrical energy store (10) comprises the following steps: first providing a housing (12) and introducing into the housing (12) at least one positive electrode (14) comprising a first active material and at least one negative electrode (16) comprising a second active material. Subsequently, a gas mixture is metered into the empty volume (22) of the housing (12) and the housing (12) is closed in a gas-tight manner. The gas mixture comprises at least one gas component which at least partially reacts with the first active material and/or the second active material after closing the housing (12). The invention further relates to an electrical energy store (10). 一种用于制造电蓄能器(10)的方法包括以下步骤：首先提供壳体(12)，并且将包括第一活性材料的至少一个正电极(14)和包括第二活性材料的至少一个负电极(16)引入到所述壳体(12)中。随后将气体混合物计量到所述壳体(12)的空容积(22)中，并且将所述壳体(12)气密地封闭。所述气体混合物包括至少一种气体成分，所述至少一种气体成分在封闭所述壳体(12)之后与所述第一活性材料和/或所述第二活性材料至少部分地反应。此外给出一种电蓄能器(10)。
