    摘要： A secondary battery includes a protection circuit module (PCM) electrically connected to a bare cell. The bare cell is wrapped with a first sheet, a water permeable second sheet placed on the first sheet, and a submergence label placed between the first sheet and the water permeable second sheet. The submergence label indicates if the bare cell has been exposed to moisture. The label sheet further has a stacking structure, wherein the second sheet is placed on top of the first sheet and the submergence label is interposed between the first sheet and the second sheet. Accordingly, it is possible to determine whether a user has disassembled, modified, or reused the battery and it is possible to easily verify whether or not the secondary battery has been submerged in a liquid due to a user's carelessness or mistake.

    摘要： A method of charging a secondary battery and a charging device that can improve stability and extend the life span of the battery. When the secondary battery includes a plurality of cells, the charging method is changed when a voltage imbalance from 100 mV to 300 mV occurs among the cells. In that range, the charging method changes from a constant current-constant voltage charging method to a pulse-charging method. When the voltage imbalance is 300 mV or more, the electricity path is blocked, shutting down the battery. When the voltage imbalance is 100 mV or less, the constant current-constant voltage charging method is maintained. The method and device also stop charging when the battery reaches full charge.
