<P>PROBLEM TO BE SOLVED: To provide a laminate type battery capable of suppressing degradation in cycle characteristics of a battery by suppressing the occurrence of variation in the connection resistive value between both electrode plates and both terminals even in charging/discharging at a high rate. <P>SOLUTION: The laminate type battery has such a structure that positive electrode collector tabs 11 are welded in a stacked state to a positive electrode collector terminal 15 and negative electrode collector tabs 12 are welded in stacked state to a negative electrode collector terminal 16. The positive electrode collector tabs 11 present between a positive electrode plate 1 and an end part 15a on the positive electrode plate 1 side of the positive electrode collector terminal 15, and/or, the negative electrode collector tabs 12 present between a negative electrode plate 2 and an end part 16a on the negative electrode plate 2 side of the negative electrode collector terminal 16, are welded each other. <P>COPYRIGHT: (C)2009,JPO&INPIT |
