In modern energy storage and supply systems, lead-acid batteries occupy a key position in many fields by virtue of their unique properties. Since the invention of French physicist Gaston Plante in 1859, lead-acid batteries have been developed for more than 160 years, and their technology is mature and widely used in various scenarios.
1. Common application areas
(1) The car starts the power supply
In the automotive field, lead-acid batteries are the "heart" of the start-up system. Every time you turn the car key, the battery instantly releases a strong current to drive the starter and drive the engine to run. Because of its large starting current, it can respond quickly in low temperature environment to ensure the smooth start of the vehicle. An ordinary fuel car needs several hundred amps of current at the start of the moment, which can be easily met by lead-acid batteries. Global car ownership is huge, by the end of 2024, China's car ownership reached 435 million, lead-acid batteries as a standard vehicle launch, market demand continues to grow.
(2) Backup power supply for communication base stations
Communication base stations need stable power to ensure smooth communication. Once the mains fails, the lead-acid battery is immediately put in to supply power to the base station equipment and maintain the normal operation of the communication network. Taking 5G base stations as an example, they have high power, large energy consumption, and strict backup power requirements. Lead-acid batteries have low cost and large capacity, and can meet the needs of base stations for several hours to tens of hours of backup time. China's 5G base station construction is advancing rapidly, as of 2024, the cumulative opening of more than 3 million, each base station needs to be equipped with lead-acid batteries as backup power, the amount of considerable.
(3) Renewable energy storage
In renewable energy generation systems such as wind and solar power, lead-acid batteries are used to store excess energy. Wind power is affected by wind speed instability, solar power depends on sunlight, and power generation fluctuates greatly. The battery stores electrical energy when there is a surplus of power generation, and releases it when there is a peak or trough of power consumption, smoothing power output and improving energy utilization efficiency. Some small wind farms and distributed photovoltaic power stations in remote areas often use lead-acid battery energy storage to reduce energy storage costs.
(4) Low speed electric vehicle power source
In the field of low-speed electric vehicles, such as electric bicycles, electric tricycles and some sightseeing vehicles, lead-acid batteries are widely used. Its affordable price is very attractive to consumers on a limited budget. And high safety, can adapt to frequent charge and discharge. According to the statistics of the China Bicycle Association, in 2024, China's electric bicycle social ownership exceeds 400 million, of which more than 70% use lead-acid batteries, and is an important means of transportation for urban short-distance travel.
2. Advantage analysis
(1) Cost advantage
From the perspective of raw materials, lead ore resources are rich, global reserves are large, and the price is relatively stable. The production process is mature, and the cost is further reduced by large-scale production. Compared with lithium-ion batteries, the unit energy cost of lead-acid batteries is only one-third to one-half of its. Taking the common 48V20Ah lead-acid battery pack as an example, the market price is 300-500 yuan, and the price of the same capacity lithium battery pack is 1000-1500 yuan, which has a significant cost advantage and is very competitive in cost-sensitive large-scale application scenarios.
(2) High security
Lead-acid battery electrolyte is sulfuric acid aqueous solution, chemical stability, non-flammable, non-explosive. Even if the battery shell is broken, it will not cause serious safety accidents such as combustion and explosion as lithium batteries. It has strong tolerance to overcharge and overdischarge, and is not easy to be damaged by improper operation during use. It is suitable for scenarios with high security requirements, such as backup power supply of communication base stations and home energy storage.
(3) High current discharge performance
The lead-acid battery can release strong current in a short time to meet the instantaneous high power requirements of the device. If the car starts instantaneously, hundreds of amps or even thousands of amps are needed, the lead-acid battery has low internal resistance, can respond quickly, easily provide large current, and ensure the smooth start of the engine. This feature is also critical in devices such as emergency lighting and power tools, which require a large current supply for an instant.
(4) Good environmental adaptability
In the temperature range of -40℃ to 60℃, the lead-acid battery can work normally. In the cold northern winter, the vehicle is difficult to start, and the lead-acid battery can maintain a certain performance to help the car start; In hot desert areas, lead-acid batteries in communication base stations can also withstand high temperature environments and provide stable power supply. In addition, it has strong adaptability to environmental factors such as humidity and altitude, and is widely used in different geographical conditions.
(5) High recycling rate
More than 90% of lead-acid batteries can be recycled. After the waste batteries are recycled, lead, plastic, sulfuric acid, etc., can be re-refined and processed to make new battery materials. The recycling industry chain is mature, and through professional recycling enterprises, environmental pollution is effectively reduced and resource waste is reduced. According to the statistics of the China Materials Recycling Association, the recycling rate of lead-acid batteries in China in 2024 will exceed 95%, contributing to the development of green recycling.
Lead-acid batteries are indispensable in many fields, with outstanding advantages in cost, safety, performance and environmental protection. Despite the challenges of new batteries, with its mature technology and wide application base, it will still play an important role in the field of energy storage and supply for some time to come, and continue to innovate and develop to meet the changing market demand.
