Abstract
The invention relates to a nickel electrode of the pasted type for a storage cell having an alkaline electrolyte, the electrode including a current collector and a paste. The electrode is manufactured by coating the collector with the paste which contains: PA1 a) an active material in powder form, having a nickel hydroxide base; PA1 b) a conductor constituted by a mixture of conductive particles and conductive fibers, the conductive particles having an average dimension D1 not greater than D/20, D being the average diameter of said active material, and the conductive fibers having an average dimension D2 not greater than D, and an average length L2 not less than 25 times the value of D2; and PA1 c) at least one polymer binder.
