Electric storage batteries

摘要

A battery includes a plurality of frames of plastics material, each frame comprising a perimeter member and one or more division elements together defining two or more active material support spaces. The frames are arranged in a stack and the perimeter member and division elements of each frame are connected to those of adjacent frames. Each support space receives an electrode, and every alternate division element has on one side two connector recesses extending over a minor proportion of its length, connector recesses in adjacent frames being in division elements that are offset from one another. The spaces on each side of each division element receive electrodes which are connected together by connectors which are received in the connector recesses. Preferably that portion of each division element which overlies a connector recess in the adjacent frame has an elongate recess in it, the connector recess and elongate recess containing a sealing material.
