AGM battery acid, full name adsorption electrolyte sealed battery acid electrolyte, is a highly stable battery technology, widely used in automotive starting, uninterruptible power supply (UPS), emergency backup power supply and other fields. This paper will introduce in detail the composition, working principle, advantages, application status and development prospect of AGM battery acid in China.

1, AGM battery acid the composition of the   AGM battery acid is mainly composed of sulfuric acid, distilled water and a small amount of additives. Among them, sulfuric acid is the main component of battery acid, accounting for about 35%-40% of the total volume; Distilled water is used to dissolve sulfuric acid to form a stable electrolyte; Additives can improve the performance of the battery, such as increasing the cycle life of the battery and reducing the self-discharge rate of the battery.

2, the working principle of AGM battery acid   The working principle of AGM battery acid is based on the sulfuric acid in the electrolyte REDOX reaction between the positive and negative electrodes, generating an electric current. During the charging process, the positive electrode absorbs sulfuric acid in the electrolyte and releases electrons. The negative electrode absorbs electrons and releases sulfuric acid. In the discharge process, the positive electrode releases sulfuric acid and absorbs electrons. The negative electrode releases electrons and absorbs sulfuric acid from the electrolyte. This reaction is carried out continuously, thus achieving the charging and discharging process of the battery.

3, the advantages of AGM battery acid

• High reliability: AGM battery acid has high reliability and can work normally in harsh environments, such as high temperature, low temperature, high humidity and so on.

• Long life: AGM battery acid cycle life is long, up to 2000 times, greatly reducing the frequency of battery replacement.

• Low self-discharge rate: AGM battery acid self-discharge rate is low, about 15-25%/ year, much lower than other types of batteries.

• simple maintenance: AGM battery acid without regular water, exhaust, reduced maintenance costs.

• Wide range of application: AGM battery acid is widely used in automotive starting, uninterruptible power supply (UPS), emergency backup power supply and other fields.

4, China's AGM battery acid application status and development prospects   In recent years, with the rapid development of China's economy, car ownership has increased year by year, AGM battery acid has been widely used in the field of automobile start-up. At the same time, the demand for AGM battery acids in areas such as uninterruptible power supplies (UPS) and emergency backup power supplies is also growing. According to statistics, China's AGM battery acid market has exceeded 10 billion yuan, and shows a growing trend year by year.

In the future, with the rapid development of new energy, electric vehicles and other fields, the market demand for AGM battery acid will be more vigorous. In addition, the Chinese government's increasing emphasis on energy saving, emission reduction and green environmental protection will also be conducive to the market promotion of AGM battery acid. It is expected that by 2025, China's AGM battery acid market will reach more than 20 billion yuan.

In summary, AGM battery acid, as an efficient and environmentally friendly battery technology, has a wide range of application prospects in China. With the continuous development of China's economy, the AGM battery acid market will usher in a better period of development.
