CATHODE MATERIAL FOR STANDBY BATTERY ACTIVATED BY WATER Russian patent published in 2014 - IPC H01M6/34 H01M10/24

Abstract RU 2510907 C2

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering and electrochemistry and refers to cathode material for water-activable standby batteries, which are mainly used for power supply of meteorological radiosondes, pilot-balloons, marine signal devices, life-saving equipment, buoys, emergency beacons. Cathode material is suggested for water-activable standby battery based on alkali metal vanadium oxide bronze, at that alkali metal vanadium oxide bronze is represented by bronze with composition of Na_1.1V₂O₅·1.2H₂O and additional copper chloride (II) CuCl₂·2H₂O and/or copper sulphate CuSO₄·6H₂O with the following ratio of components in wt %: alkali metal vanadium oxide bronze - 83.3÷52.6, copper (II) sulphate and/or chloride - 47.4÷16.7, at that mixing of components is made by fine wet milling in presence of water and/or alcohol, e.g., ethanol.

EFFECT: development of cathode material composition characterised by high and stable discharge voltage, low rate of discharge and high temperature of self-heating.
