Estimating the term…
A module battery of sealed alkaline storage battery comprises a plurality of cells stacked in one direction each of which comprises a battery casing of a synthetic resin, an electrolyte and an electrode group accommodated in the battery casing and a lid with a safety bent sealingly fitted to the opening of the battery casing; wherein the cells are bound in the direction of stacking by binding members for coupling the end plates at the ends of the stacked battery assembly to each other; the cells are butted to each other by a plurality of parallel ribs formed on the outer surface of the battery casing along the direction of stacking thereby to form spaces for allowing air flow between the cells, a thickness of the side wall of the battery casing along the direction of stacking is 1 to 3 mm, a rib height 1 to 2 mm, a rib interval 10 to 15 mm, and a rib width 3 to 10 mm.
A cell of a sealed alkaline storage battery comprising:
A module battery (31) comprising a plurality of cells (10) stacked in one direction forming a stacked assembly, each of said cells comprising a battery casing (12) of a synthetic resin, an alkaline electrolyte and an electrode group (11) accommodated in said battery casing, and a lid (13) with a safety vent (16) sealingly fitted to the opening of said battery casing;
A battery casing of a synthetic resin for configuring a module battery by stacking a plurality of cells in one direction, wherein a plurality of parallel ribs in butted relation with an adjacent battery casing are formed on the outer surfaces of side walls of said casing along the direction of stacking, a thickness of said side walls along the direction of stacking is from 1 mm to 3 mm and a thickness of the other casing side walls from 3 mm to 5 mm.
