Nickel-hydrogen batteries are a new type of rechargeable battery, consisting of multiple components and modules. In this article, we will detail the components and modules of nickel-hydrogen batteries.

Firstly, the main components of nickel-hydrogen batteries include the positive electrode, negative electrode, electrolyte, and separator. The positive electrode is typically made of nickel hydroxide (Ni(OH)2), while the negative electrode is made of titanium hydride (TiH2) or zirconium hydride (ZrH2). The electrolyte is usually a potassium hydroxide (KOH) solution, which serves to conduct electricity and transfer ions in the battery. The separator is used to isolate the positive and negative electrodes, preventing short circuits and mixing of the electrolyte.

In addition to the main components, nickel-hydrogen batteries also include auxiliary components and modules such as the battery casing, terminals, protection board, and temperature control system. The battery casing is typically made of metal or plastic materials, used to contain the internal components of the battery and protect it from external influences. Terminals are used to connect the battery to external circuits and transfer electrical energy. The protection board is used to monitor the battery's voltage, temperature, and current to ensure safe operation. The temperature control system is used to regulate the battery's temperature, preventing overheating or overcooling that could degrade or damage the battery's performance.

Furthermore, nickel-hydrogen batteries also include other modules such as the battery management system (BMS), charge-discharge controller, and battery packaging. The battery management system is used to monitor and manage the battery's status, including voltage, temperature, current, and capacity, to ensure safe and stable operation. The charge-discharge controller is used to control the battery's charging and discharging processes to ensure performance and longevity. Battery packaging is used to integrate the battery's components and modules into a complete battery assembly.

In conclusion, nickel-hydrogen batteries are complex systems composed of multiple components and modules, each playing a crucial role in ensuring the battery's safety, stability, and efficiency. With advancements in technology, the performance and applications of nickel-hydrogen batteries will continue to expand, bringing more convenience and possibilities to human life and work. Through this article, we hope readers have gained a deeper understanding of the components and modules of nickel-hydrogen batteries.
