WINDING TYPE SEALED LEAD-ACID BATTERY

摘要: PROBLEM TO BE SOLVED: To provide a winding type sealed lead-acid battery having group formed by belt-shaped positive electrode and negative through separator, in which the separator is present outermost periphery of group, end lower part roundly cut out. SOLUTION: The base to be out represented following formula:h/6≤m≤a≤l≤(1000×D/h) 1/2 . Wherein, h: length from stop tape, m: tangent naturally jumping up part, a: cutting l: lateral turned D: diameter. COPYRIGHT: (C)2007,JPO&INPIT
