Abstract
A multi-cell battery comprising 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 adjoining frames also being of opposite polarity.
Claims9
A multi-cell battery including a plurality of frames formed of a moldable 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 support 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 support areas secured in a sealed relationship to the corresponding portions in adjacent frames to form partitions between adjacent cells of the battery.
A multi-cell battery including a plurality fo frames formed of a moldable 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, 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 comprising a plurality of frames of a moldable 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 interfitting 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, one of said sides of each frame having metallic terminal elements embedded therein and projecting externally of the frame and into the receiving area adjacent said side of the frame, metallic intercell connector elements embedded in each alternate division element and extending into the receiving areas on opposite sides of said division element, and individual masses of active battery material support in each receiving 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, whereby each pair of frames form a plurality of single cells electrically connected in series.
