ABSTRACT This invention relates to a multi-cell battery which includes a plurality of frames formed of a mouldable material which is electrically insulating at the intended oper- ating voltage of the battery and is inert to the active materials of the battery and any material produced during operation of the battery. Each frame defines a plurality of separate material receiving areas arranged in side by side relationship across the width of the frame and each frame includes portions forming divisions between adjacent support areas of the frame. The frames are arranged in a side by side relationship in a direction normal to the width of the frame with the portions of each frame forming the divisions between adjacent receiving areas secured in a sealed relationship to the corresponding portions in adjacent frames to form partitions between adjacent cells of the battery. Each alternate frame has an electrolyte porous separator member spanning each support area thereof and secured to the portions of the frame defining the support area. Individual masses of active battery material are supported in each support area of the remaining frames so that each said area forms a plate of the battery. The active battery material in respective areas is selected so that adjacent areas in each frame form plates of opposite polarity and adjacent areas on opposite sides of each separator member form plates of opposite polarity. Each said alternate frame has a plurality of spacer elements integral there- with, the spacer elements being arranged so that each spacer member has at least one spacer element extending partly across that surface of the separator member directed to the support area of an adjacent frame carrying active material of positive polarity.
