专利汇可以提供RECHARGEABLE ELECTROCHEMICAL CELL专利检索,专利查询,专利分析的服务。并且The invention relates to a rechargeable electrochemical cell with a negative electrode that contains an active metal in the charged state that is selected from the group consisting of the alkali metals, alkaline earth metals and the metals of the second subgroup of the periodic system, a sulfur dioxide based electrolyte solution and a positive electrode that contains the active metal and that discharges ions into the electrolyte solution when the cell is recharged. The negative electrode undergoes a self-discharge reaction in which the sulfur dioxide of the electrolyte solution reacts with the active metal of the negative electrode, giving a hardly soluble compound. According to the invention, the electrochemical charge of the sulfur dioxide, calculated by one Faraday per mole of sulfur dioxide, in the cell is smaller than the electrochemically equivalent charge of the active metal that can be theoretically stored in the positive electrode.,下面是RECHARGEABLE ELECTROCHEMICAL CELL专利的具体信息内容。
