    摘要： A battery module includes a plurality of cells (6) accommodating an electrode plate group (5) and an electrolyte, and a single integrated battery case (2) for accommodating the plurality of cells (6), the cells may be connected through lead portions protruding sideways on the lateral side of the cells. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99 - 40:60 at a temperature of 25°C. Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.

    摘要： A hydrogen-absorption alloy electrode includes, as a principal material, particles of a hydrogen-absorption alloy containing a rare earth element, Ni, Co, Al and Mn and leads to reduced deviation in battery characteristics after charging/discharging cycles by having the size distribution of the alloy particles limited such that d90/d10 ≤ 8 and d90-d10 ≤ 50µm, where di (where i varies from 0 to 100) means a particle size at which cumulative size frequency with respect to the entire particles is i%. The alloy particles are constructed such that on the surface of the alloy particles, at least one of the following relationships holds: (the amount of Al on the surface/the amount of Al in the alloy)

    摘要： A battery assembly includes a plurality of battery modules electrically connected together, each battery module acting as a secondary battery and including an electrode group, an electrolyte, a container for housing the electrode group and the electrolyte, and a safety valve operating in accordance with the internal pressure of the container. The working pressure of each safety valve is set so that the safety valve of at least one battery module is opened when the at least one battery module has its maximum internal pressure or less during the charge equalization. It is possible to provide a battery assembly that can improve the reliability of the container strength by keeping the working pressure of each safety valve lower than the pressure that the container resists even under elevated temperature conditions.
