METHOD FOR REGENERATION OF WASTE STORAGE BATTERIES Russian patent published in 1997 - IPC

Abstract RU 2088002 C1

FIELD: chemical power supplies. SUBSTANCE: active body of positive electrodes is treated by temperature of 600- 650 C for 60-90 min. Cake is ground and sieved in order to separate fractions of 500-100 mcm and 100-40 mcm. Latter fraction is mixed with distilled water, applied on current lead and showered with particles of 500-100 mcm, pressed, dried and treated with solution of sylvic acid. Active body of negative electrodes is treated by temperature of 800-850 C for 60-90 min and separated according to separation of active body of positive electrodes. Resulted fraction of particles of 100-40 mcm is mixed with same fraction of active body of positive electrodes, is mixed with water, deposited on current lead, showered with layer of fraction of negative active body of particles of 500-100 mcm, pressed, dried and shaped. Positive electrodes are shaped together with shaped negative electrodes. EFFECT: increased efficiency of regeneration, decreased pollution, lack of waste.
