What are the processing technologies for Nickel Hydride Batteries?

Processing technologies for Nickel Hydride Batteries

Stirring, coating, winding and testing are important processing technologies for Nickel Hydride Batteries.

1. Slurry stirring is an important part of lithium battery equipment. The positive electrode slurry of Nickel Hydride Batteries is composed of adhesives, conductive agents, positive electrode materials, etc., and the negative electrode slurry is composed of adhesives, graphite carbon powder, etc.; the preparation of positive and negative electrode slurries includes the mixing, dissolution and dispersion of liquids and liquids and solid materials; the quality of slurry dispersion directly affects the quality and performance of Nickel Hydride Batteries.

2. Coating determines the consistency and superiority of batteries and occupies a technical position in battery manufacturing. Regardless of the type of battery (such as cylindrical or square), the coating machine used in manufacturing is the same; different types of batteries require different types of winding machines.

3. In addition to lithium battery winding machines, there are capacitor winding machines, textile winding machines, etc. According to the operation mode of the machine, it can be divided into manual winding machines, semi-automatic winding machines and fully automatic winding machines.

4. The importance of testing items is becoming increasingly prominent. Nickel Hydride Batteries are prone to burn or explode due to short circuits, overcharging, etc. In applications, they will form finished batteries with protection boards; in applications with high energy density, Nickel Hydride Batteries need to be combined in series and parallel to form lithium battery packs, which are managed by battery management systems (BMS).

It can be seen that the processing technology of Nickel Hydride Batteries is relatively long, including more than 50 processes, and more than 50 types of equipment are required accordingly. The entire manufacturing process can be divided into four process segments: pole piece production, cell assembly, cell activation detection, and battery packaging. Among them, the equipment related to pole piece production is called front-end equipment, the equipment related to cell production is mid-end equipment, and the equipment for cell activation detection and battery packaging is back-end equipment.

In recent years, lithium battery processing has developed towards integration, whole-line, and automation. Lithium battery automation processing lines supply standardized products to customers, and traditional development methods cannot cope with the rapidly changing needs of customers.

The quality of Nickel Hydride Batteries is crucial. At present, the most important problem in the industrialization of Nickel Hydride Batteries in China is the poor consistency of battery quality. The reason is that manual operation and poor equipment accuracy lead to large system errors and inability to sustain processing. To fundamentally solve the problem of poor quality consistency in lithium battery batch production, it is necessary to improve the control accuracy of processing equipment and the automation level of processing lines.
