FIELD: chemical current supplies; lead accumulators. SUBSTANCE: proposed accumulator has negative and positive plates with separators in-between and electrolyte; press-fitted in positive plates is oxide-resistant synthetic cloth in the form of elastic knitted fabric capable of expanding in width by 200-250% and having 170-200 holes (stitches) per 1 cu. cm. Knitted fabric is used in the form of roll pulled onto positive plate while expanding in crosswise direction and sealed over bottom edge of electrode. Ratio of knitted fabric sleeve width to positive electrode width is 0.5 0.7. Proposed design of accumulator enables extending its service period by 1.5 to 2 times. EFFECT: enhanced service life of lead accumulator. 3 cl, 3 dwg, 1 tbl, 2 ex
