Patent

CA 2074159

The invention reduces the number of cycles of charge-discharge operation required in the formation process involved in manufacturing of a sealed type nickel-hydrogen cell having a large high-rate discharge capacity. In the formation process, a sealed type nickel-hydrogen cell is subjected to at least one cycle of charge-discharge operation and thereafter kept at a temperature in the range of about 30°C to 60°C for a predetermined length of time.

La présente invention permet de réduire le nombre de cycles charge-décharge requis dans le procédé de formation mis en oeuvre lors de la fabrication d'une pile étanche nickel-hydrogène à haute capacité de décharge rapide. Au cours du procédé de formation, la pile est soumise à au moins un cycle de charge-décharge, puis est conservée pendant une période déterminée à une température comprise entre environ 30 degrés C et 60 degrés C.
