The introduction of the maintenance-free battery is very impact on the SLI battery market. "Maintenance" means that there is no need to add water to the electrolyte during the use period of 2-5 years. The standard lead-acid battery is very small, and most of the water consumed is due to electrolysis to generate hydrogen and oxygen, a small amount of impurities can reduce the overvoltage of the process, accelerate water consumption, such as antimony, arsenic, drill, magnesium , Nickel, platinum and antimony are all harmful substances, and even trace will have an adverse effect. When developing an MF battery, two ways to reduce water are often used:1. Reduce gas generating rate under normal use conditions;
2. Promote gas to generate water.
Since the SLI battery is typically charged under constant pressure, the MF battery should be designed such that such materials should have no obvious gas generation within the stable output voltage range of DC generators or AC generators. This means that such a battery must have improved positive edge plates and alloy plates, and the content of antimony in alloy should be significantly reduced or even zero, and the calcium or a group of metals (such as ruthenium / tin / aluminum). The calcium alloy plate gate can significantly improve the precipitation characteristics of hydrogen, but the calcium alloy is poor, and it is difficult to use this material into a complex grid. The MF battery is often formed by forming a gel or a porous glass separator to limit the flow of electrolyte by forming a gel or a porous glass separator. The battery design has a leak-proof housing with a valve to release high air pressure, so sometimes it is called a "semi-sealing" system. Such a battery has a very high charging capacity compared to many usual batteries, and it is still 30% of its capacity after a year. Another advantage of it is that there is no escape of acid fog, and the metal components near the battery will not have corrosion.
