Problems solved by technology
The nickel strip itself has a relatively large resistance, and the small contact surface between the copper mesh and the bottom of the steel case will increase the internal resistance of the battery. Therefore, the internal resistance of the battery of the above patent is relatively high, and the current density is high, which is not conducive to fast charging and charging. discharge

Abstract
The invention relates to a dynamic high-capacity nickel-hydrogen battery and a production process thereof. By applying a current collecting plate and a current collecting body, the internal resistance of the battery is greatly reduced. The production process mainly comprises the following steps: preparing a nickel battery, preparing a nickel battery, coiling, welding, and moreover carrying out sulfonation treatment on a membrane. By adopting the production process, the internal resistance of the battery is greatly reduced, thereby achieving the effects of charging and discharging the nickel-hydrogen battery in a short time.
Description
technical field [0001] The invention relates to a production process of a nickel-hydrogen battery, in particular to a production process of a nickel-hydrogen battery capable of fast charging or discharging. Background technique [0002] Ni-MH battery is a new type of alkaline storage battery that has been vigorously researched and developed both at home and abroad in recent years. Compared with nickel-cadmium batteries, nickel-metal hydride batteries have higher energy density, and because nickel-hydrogen batteries do not use cadmium, they are less polluting to the environment. With the development of miniaturization and multi-function of equipment, the battery as its power source is required to have small volume and high capacity. [0003] For a long time, the power tool market has been monopolized by nickel-cadmium batteries. Cadmium is highly toxic and will cause serious pollution to the environment. In addition, cadmium was banned in Europe in 2006. Therefore, the devel...
