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.

The influence of lithium on capacity of positive nickel electrode was investigated during the exploitation of a tight nickel-cadmium accumulator. The main effect of lithium was found to deal with the surface sorption of oxygen by the active mass of the positive electrode that leads to sufficiently high extravoltagc of molecular oxygen formation. This effect allows low pressure of gas in a system to be kept and possibility a charge tip to be carried out a level equal oxidation degree about 0,7-0,8,

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.
