Novel high-capacity nickel-metal hydride battery

Abstract

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.

Description

technical field [0001] The invention relates to a nickel-hydrogen battery, in particular to a nickel-hydrogen battery that can be charged or discharged quickly. Background technique [0002] With the improvement of social modernization level and the improvement of environmental protection requirements, nickel-metal hydride batteries have been more and more widely used. Ni-MH batteries are widely used due to their rechargeable and environmentally friendly characteristics. With the wide application of Ni-MH batteries, the requirements for the capacity of Ni-MH batteries are getting higher and higher. Conventional Ni-MH rechargeable batteries are often unable to reach users due to their low capacity. Requirements for battery life. The Ni-MH rechargeable battery also cannot meet the needs of the market due to the low production efficiency due to the welding of the positive electrode collector plate during assembly. [0003] Compared with nickel-cadmium batteries, nickel-hydrog...
