    摘要: This invention relates to an electrochemical cell having spirally wound electrodes and an electrolyte which enhances plating of the anode metal during voltage reversal. The safety of such cells is improved by concentrating the current, during voltage reversal, between an outer segment of the anode and a metal sheet connected to the cathode whereby anode metal plates only onto the metal sheet. Thus, the hazardous condition of plating anode metal onto the cathode is avoided.

    摘要: The safety of a non-pressurized electrochemical cell such as a Li/MnO.sub.2 cell, having a safety pressure vent and an organic electrolyte solvent is enhanced by, in conjunction with said vent, providing said organic electrolyte solvent with at least 80% by volume of a volatile component, such as dimethoxyethane, having a boiling point between 30.degree. C. to 130.degree. C. Upon cell venting, under abuse conditions, the cell is thereby rapidly evacuated and safely rendered inoperable under further abuse conditions.

    摘要: A battery pack and a method of operating a battery system. The battery pack includes a rechargeable battery and a processor for monitoring the battery during charging and discharging. The processor receives data values representing the battery voltage, temperature and current, and the processor performs a series of calculations using those data values. The processor has normal, standby and sleep modes. In the normal mode, the processor performs the series of calculations at first regular cycles, and in the standby mode, the processor performs the series of calculations at second regular cycles, which are longer than the first cycles. Preferably, the processor enters the standby mode when the battery current falls below a predetermined current level, and the processor enters the sleep mode when the battery voltage falls below a first predetermined voltage level. Also, the processor exits the sleep mode when the battery voltage rises above a second predetermined voltage level higher than the first predetermined voltage level.
