The corrosion resistance of fishing boat energy storage batteries in marine environments is a critical requirement because the marine environment is full of salt spray, humidity and potentially chemically aggressive substances, which can have a serious impact on the performance and life of the battery. The following are the detailed requirements for the corrosion resistance of fishing boat energy storage batteries in marine environments:
First, the battery casing and seals must have excellent salt spray and moisture resistance. The salt content in the marine environment is high, and salt particles will adhere to the surface of the battery and even penetrate into the battery, causing circuit short circuits or corrosion of internal components. Therefore, the shell material of the battery should be corrosion-resistant and anti-oxidation metal materials or polymer materials, and the seals should be made of materials with good sealing performance and aging resistance to ensure the long-term stable operation of the battery in the marine environment.
Secondly, the electrolyte and electrode materials inside the battery also need to have good corrosion resistance. As an important component of the battery, the stability of the electrolyte directly affects the performance of the battery. In a marine environment, electrolytes can be corroded by humidity and salt, causing battery performance to degrade. Therefore, an electrolyte with high stability and less susceptible to environmental influences should be selected. At the same time, the electrode material should also have anti-corrosion properties and be able to withstand chemical erosion in the marine environment.
In addition, the battery’s connecting wires and interfaces also need to pay attention to their corrosion resistance. Cables serve as a bridge between batteries and external devices, and their quality and performance directly affect the performance of the battery. In a marine environment, connecting wires can be corroded by salt and humidity, causing poor contact or breakage. Therefore, corrosion-resistant and aging-resistant connection line materials should be used, and the interface design should be reasonable and the connection should be firm.
Finally, in order to further improve the corrosion resistance of the battery, some additional protective measures can be taken. For example, a layer of anti-corrosion coating is applied to the outside of the battery to form a protective layer to isolate the corrosion of salt and moisture; or a protective cover is installed around the battery to reduce the direct impact of salt and moisture on the battery.
To sum up, the corrosion resistance requirements of fishing boat energy storage batteries in the marine environment are very strict. From the casing to the internal components, from the electrolyte to the electrode materials, excellent corrosion resistance is required to ensure the long-term stable operation of the battery in the marine environment.
