Abstract
A multi-cell battery comprises a plurality of frames each divided into a number of side by side active paste support areas. The frames are assembled and secured together in a stacked formation so that the perimeter portions of the frames form the top, bottom and two opposite sides of the battery, and the divisions in the frames form cell partitions.Each frame is pasted with active material to form plates with adjacent plates in each frame being of opposite polarity and adjacent plates in each frame being of opposite polarity and adjacent plates in adjoining frames also being of opposite polarity. Electrolyte-porous separator material is provided between adjacent plates in adjoining frames.
Claims10
A multi-cell battery including a plurality of frames formed of a mouldable material which is electrically insulating at the intended operating 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 defining a plurality of separate material receiving areas in side by side relationship across the width of the frame, each frame including portions forming divisions between adjacent support areas of the frame, the frames being 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, and electrolyte porous separator member located between each two adjacent frames in the assembly of frames spanning each support area thereof and sealed to the portions of the frame defining said support area, and individual masses of active battery material support in each area of each frame so that each area forms a plate of the battery, the active battery material in respective areas being selected so that adjacent areas in each frame form plates of opposite polarity and adjacent areas in adjoining frames form plates of opposite polarity.
A multi-cell battery including a plurality of frames formed of a mouldable material which is electrically insulating at the intended operating 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 defining a plurality of separate material receiving areas arranged in side by side relationship across the width of the frame, each frame including portions forming divisions between adjacent support areas of the frame, the frames being 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 having an electrolyte porous separator member spanning each support area thereof and secured to the portions of the frame defining said support area, and individual masses of active battery material 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 being 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.
A multi-cell battery comprising a plurality of frames formed of a mouldable material which is electrically insulating at the intended operating 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 including a continuous perimeter member of rectangular shape and a number of division elements parallel to two opposite sides of the frame, said perimeter member and division elements defining a plurality of active material support areas arranged in side by side relation across the width of the frame, the frames being arranged in side by side relation in a direction normal to the width of the frames, the perimeter member and division elements of each frame inter-fitting with the corresponding portion of the adjacent frame and being secured thereto in sealed relation to form two opposite side walls, a top, a bottom and a plurality of cell partitions of the battery, each alternate frame having an electrolyte porous separator member spanning each support area thereof and secured to the portions of the frame defining said support area, and individual masses of active battery material 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 being 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, one of said sides of each remaining frame having metallic terminal elements embedded therein and projecting externally of the frame and into the active battery material in the support area adjacent said side of the remaining frame, metallic intercell connector elements embedded in each alternative division element of each remaining frame and extending into the active battery material in the support areas on opposite sides of said division element.
