FIELD: chemistry.
SUBSTANCE: additive to claimed zinc anode mass is an electroconductive fine ceramic powder of titanium nitride (TiN), oxidised in air or pure oxygen medium at 150 to 800°C for a period from 5 minutes to 15 hours before introduction to composition of active zinc anode mass.
EFFECT: significant increase in life span measured in charge-discharge cycle for secondary alkaline electrochemical generator.
