| 摘要 |
The invention provides a battery, which can improve battery performance. In the battery, a cathode and an anode are faced with a high molecular weight electrolyte in between, and wound. The anode comprises an anode current collector and an anode active material layer. The anode active material layer contains Si, Sn, or an alloy thereof. The anode active material layer is preferably formed by vapor-phase deposition method, liquid-phase deposition method, or sintering method. The anode active material layer is preferably alloyed with the anode current collector at least on part of an interface with the anode current collector. The high molecular weight electrolyte contains an electrolytic solution, and a high molecular weight compound having a structure wherein a polymerization compound having an acrylate group or a methacrylate group and containing no ether group is polymerized. |
