    Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery in which a resistance rise is inhibited and an internal short circuit is prevented to achieve excellent charge-discharge cycle characteristics by preventing an electrolyte shortage in an electrode layer, preventing the occurrence of a gap, and allowing the accommodation of variations in cell thickness. SOLUTION: The nonaqueous electrolyte secondary battery comprises a storage element including a positive electrode, a negative electrode comprising an active material containing an element which can be alloyed with lithium, and a separator containing an electrolyte, and the porosity of the separator decreases gradually with increasing distance from the negative electrode side toward the positive electrode side.

    Abstract: PROBLEM TO BE SOLVED: To provide a battery pack, lighter, more compact and downsized, and with high productivity.
    SOLUTION: The battery pack includes a battery cell 209 having an electrode terminal formed on its upper surface, and a protection circuit module (PCM) block 203 mounted on the battery cell. One or more connection holes for electrically connecting between the battery cell and the PCM block are punched on the PCM block so as the connection part between the battery cell and the PCM block to be exposed outside of the upper surface of the battery cell. The battery pack is made lighter, more compact and downsized, whereby, electronic equipment using the battery pack is reduced in its size as a whole, and therefore, workability is enhanced with simplified assembling processes, manufacturing cost is reduced through reduction of the number of components, and productivity is enhanced through reduction of the number of operation steps by eliminating additional mounting steps.
