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.
