| 摘要 |
A method of manufacturing a battery having at least one electrochemical cell comprising forming a negative electrode (5), a positive electrode (7), and a solid electrolyte (6), and dispersing in the solid electrolyte (6) a first material so that there is a concentration of zero or substantially zero of said first material in the vicinity of a second material (5) of the battery with which it would otherwise react. The electrolyte (6) may be formed with a concentration gradient of said first material across it, or may be formed in two or more distinct layers having differing concentrations of the first material therein. The battery may be a lithium battery containing volatile constituents such as propylene carbonate (PC) or ethylene carbonate (EC) and water as a contaminant which could react with the lithium metal or alloy (5). |
