NICKEL-HYDROGEN STORAGE BATTERY OF LONG CYCLIC LIFE Russian patent published in 2005 - IPC

FIELD: electrical engineering.

SUBSTANCE: proposed hermetically sealed nickel-hydrogen storage battery has block of electrochemical groups placed in case, interconnected through current duct, and isolated from each other by means of gas separator made in the form of double-line intersection of threads with their lines relatively offset, ratio of thread diameter to distance between threads being chosen between 0.4 and 1, respectively. Gas separator threads are made of polypropylene and thread diameter is minimum 0.9 mm.

EFFECT: reduced mechanical thrusts on hydrogen electrode and, consequently, enhanced reliability of battery.
