Advantages and disadvantages of desulfurized lead-acid batteries
Lead-acid batteries, as a type of battery with a long history and wide application, are widely used in many occasions because of their advantages such as low cost, high recycling rate and mature technology. However, the traditional lead-acid battery exists the phenomenon of sulfation, long-term use is easy to lead to the deterioration of battery performance. Therefore, desulfurization technology came into being, which aims to improve the problem of lead-acid battery vulcanization and extend the service life of the battery. This article will introduce the advantages and disadvantages of desulfurized lead-acid batteries in detail.

Advantages of desulfurized lead-acid batteries

Desulfurization effect is significant: Desulphurized lead-acid batteries through specific charging technology or additives, effectively avoid or reduce the accumulation of sulfate on the battery plate, which usually occurs in the charging and discharging process of traditional lead-acid batteries. Through desulphurization, the charging acceptance and charging efficiency of the battery are improved, thus improving the overall performance.

Extended service life: sulfation is one of the main reasons for the failure of lead-acid batteries. The lead-acid battery optimized after desulfurization can significantly slow down the process of sulfation, avoid the hardening of the plate and the loss of active substances, so the service life of the lead-acid battery is longer than that of the ordinary lead-acid battery.


Low maintenance costs: In view of the problem of desulfurization lead-acid battery vulcanization has been effectively controlled and improved, so the maintenance and maintenance needs are relatively less in the normal use process, indirectly reducing operating costs.

Improved environmental performance: Desulphurization technology helps to reduce waste and environmental pollution of lead-acid batteries. In addition, the battery waste materials after desulfurization are also more suitable for recycling, which improves the environmental performance of the battery from one side.

2. Disadvantages of desulfurized lead-acid batteries

Increased technical costs: Compared with traditional lead-acid batteries, batteries using desulfurization technology may require more advanced materials and technologies in the manufacturing process, resulting in increased costs. This cost increase could affect the final selling price of the battery.

Limited desulfurization technology: Although desulfurization can delay the process of sulfation, it cannot completely avoid. In some use environments, such as frequent deep discharge, the performance of desulfurized lead-acid batteries will still gradually decline.

Technical applicability: Currently there are different desulfurization technologies and products on the market, and the desulfurization effect of different suppliers may be different. At the same time, not all applications are suitable for the use of desulfurization lead-acid batteries, users need to carefully choose according to actual needs.

Energy density and current output: Although desulfurization technology has improved the vulcanization problem of lead-acid batteries, in terms of energy density and maximum current output, desulphurized lead-acid batteries are still not comparable to modern battery technology such as lithium batteries.

The scope and prospect of desulfurization lead-acid batteries

Lead-acid batteries improved by desulfurization technology are widely used in many fields such as UPS (uninterruptible power supply), solar energy storage systems, electric vehicles, power stations and communication base stations. In these areas, long-term stable power output and high reliability are very critical, and desulphurized lead-acid batteries can just meet these requirements.

With the global attention to renewable energy and environmental protection, desulfurization lead-acid batteries with its environmental protection, economic and stable characteristics, will have a broad market potential and development prospects. However, in the future, it still needs to face the competition of new energy storage technologies such as lithium batteries, and continuous technological innovation and cost optimization will be an important driving force for the development of desulphurized lead-acid battery industry.

Overall, desulphurized lead-acid batteries with their unique advantages occupy a place in the field of power storage and supply. Despite some shortcomings and challenges, with the progress of science and technology and changes in market demand, the performance and application range of desulfurized lead-acid batteries will be further expanded and improved.
