герметичный никель-кадмиевый аккумулятор

The problems of providing the reliable uninterrupted power supply of radio-electronic equipment using the ac power supply source as the primary power supply are examined. Hermetic NiCd accumulator battery with a long operating time is suggested as a standby power supply. The charging device scheme is developed providing the battery permanent readiness for operation. The device models have been manufactured and tested.

The aim of this work was to explore the possibility of designing a valve-regulated nickel-cadmium KGL300P battery on the basis of the commercial lamellar-electrode KL300P battery with the use of a universal principle of compulsory oxygen pumping into the cadmium electrode's pores. The unwoven geotextile TU 8397-056-05283280-2002 linen of the Geocom A-200 brand can be used as a separator material in the design of such a battery.

It is shown from analysis of charging current and voltage change on the terminals of sealed Ni-Cd battery at thermal runaway, that thermal runaway is accompanied by a new high-power electrochemical reaction, going at battery voltage of approximately 0.55 V.
