In the mean time, i test the separator ’ s performance, including the rate of hole 、 the performance of absorbing electrolyte and the conductance eletrochemical steady range 、 machine intensity test, and then make bettery to test its cycle performance. the test result show that, the spreading separator get better performance, when dbp ’ s percentum reach 50 %, and dry temperature reach 90, after ultraviolet radiation disposal. the test show that, the separator has high conductance reach 6. 1 10 - 3s / cm ( 25 ), and the machine intensity can reach 3. 92 mpa, this separator can meet the need of making bettery, the bettery capability will go down after 30 cycle. and the bettery show worse performance under high temperature, under 70, the bettery will get fire. making the intensified seprator, i find that when dbp % : pvdf % = 40 % : 60 %, dbp % + pvdf % : sio2 % = 70 % : 30 %, the separator get

Abstract : the rechargeble batteries are used for backup power internal electrically equipments and instruments. but batteries lifetime usually is shorten by overwork and then malfunctions of equipment are induced. to avoid the complexion described above, the protection circuit against overwork is designed. it is based upon the voltage comparator and regulator. it will light up a red led when the volume of the batteries discharged close upon 50 % ; it will switch off the load automatically when it discharged closing to 80 % of their energy capacity, thus overwork of batteries can be avoided and lifetime may be extended
