METHOD FOR TUBULAR-PLATE CADMIUM ELECTRODE Russian patent published in 2009 - IPC H01M4/26 H01M10/30 

FIELD: electricity.

SUBSTANCE: invention is attributed to electric engineering in particular to alkaline accumulator with tubular-plate electrodes. According to the invention this is method for tubular-plate cadmium electrode for alkaline accumulator manufacturing through active mass applying to current collector and treating with ammonia-water mixture. In this process sponge nickel frame is used as current collector, active mass is prepared of cadmium oxide with addition of nickel hydroxide in quantity of 5÷7 wt %. Active mass is treated by ammonia spirit, then filtered, dried at temperature of 70÷80°C for 1.5÷2.0 hours and sieved through separator with mesh size of 350x350 micron. Active mass is applied on current collector in amount of 0.5÷0.6 g/cm and squized. Active mass is treated by 5% ammonia spirit in amounts of 2 l per 1 kg of active mass for 20÷30 minutes. Electrode with active mass is saturated in 2.5% ammonia spirit for 20÷30 minutes and dried in air for at least 3 hours. Prior to applying on current collector, active mass is processed by sprinkling with straw oil in amounts of 20÷25 g per 1 kg of active mass.

EFFECT: electrode mechanical strength increase.
