The invention discloses a novel high-capacity
nickel-
metal hydride battery, and aims to provide a
nickel-
metal hydride battery capable of rapid charging or discharging, and the installation difficultyof a
battery cell is reduced, and simultaneously the problem that the contact of pole pieces and a nut cap or a steel shell of the battery is not in place is solved. The novel high-capacity
nickel-
metal hydride battery comprises a steel shell and a
battery cell, wherein the pole pieces of the
battery cell are connected with the nut cap and the steel shell of the battery respectively, the cylindrical battery
cell is installed inside the steel shell through an insulating sleeve, and a plurality of lug holes are formed in two ends of the insulating sleeve respectively; a
nickel electrode at theupper end of the battery
cell and a
hydrogen electrode at the lower end of the battery
cell are provided with integral lugs distributed at intervals respectively, and the lugs stretch out of the lug holes and are bent; a contact spring plate is installed at each of two ends or one end of the insulating sleeve, and the contact spring plate is in tight contact with the nut cap and / or the steel shellof the battery. The novel high-capacity nickel-metal hydride battery has the advantages that firstly, the insulating sleeve is in clearance fit with the inner wall of the steel shell, the battery iseasy to install and position, and the installation difficulty is reduced; and secondly, the contact spring plate is installed at each of two ends or one end of the insulating sleeve, so that the
internal resistance of the battery is reduced, internal virtual connection is prevented, and the quality of the product is promoted.
