Problems solved by technology

[0003] As a pure electric vehicle, in order to ensure the continuation mileage, the battery capacity is generally required to be relatively large. The cost of the traditional square power Ni-MH battery is high, and the larger the capacity design, the power performance and safety performance of the battery will be relatively reduced.

The novel high-capacity power nickel-metal hydride battery provided by the invention has the properties of simple and reasonable structure, high automation degree of production and the like.

Description

technical field [0001] The invention relates to a novel high-capacity power nickel-metal hydride battery, which belongs to the technical field of new energy batteries. Background technique [0002] At present, most new energy vehicle batteries use power lithium-ion batteries and power nickel-metal hydride batteries. Compared with lithium batteries, power nickel-metal hydride batteries have mature technology, good high and low temperature performance, good safety performance, and can be charged and discharged with high current, but mainly because of their high cost. , restricting the application and popularization of power nickel metal hydride batteries in automobiles. However, nickel-metal hydride batteries for hybrid electric vehicles and electric vehicles still have advantages and markets, because hybrid electric vehicle batteries have small capacity and relatively low cost, and electric vehicles in cold regions currently only have nickel-metal hydride batteries that can b...
