However, lead-acid batteries are not without chances, and with their deep technical heritage and unique advantages, they have shown strong competitiveness in many aspects.

On the track of energy storage technology, the traditional lead-acid battery and the emerging new energy storage technology are starting a fierce competition. From the peak adjustment of the early power system to the outbreak of energy storage demand under the new energy wave today, the results of this showdown have far-reaching implications. However, lead-acid batteries are not without chances, and with their deep technical heritage and unique advantages, they have shown strong competitiveness in many aspects.

## Cost cornerstone: hard to shake the price advantage

Cost is a key factor in the commercialization of energy storage technology, and lead-acid batteries are called the "king of cost performance" in this regard. Its raw material sources are wide, lead and sulfuric acid are abundant in global mineral resources, supply is stable and the price is relatively low. Taking the common 12V and 100Ah lead-acid batteries as an example, the market price is usually in the 500-1000 yuan range, and the new lithium-ion batteries of the same capacity are often 2-3 times the price of lead-acid batteries. Large-scale production is to consolidate the cost advantage of lead-acid batteries, mature production processes and huge industrial scale, making unit manufacturing costs significantly reduced. In some extremely cost-sensitive application scenarios, such as ordinary household emergency energy storage, electric bicycle power supply, etc., lead-acid batteries firmly dominate with low price advantages, and new energy storage technology is difficult to break through its price defense line in the short term.

## Technology maturity: proven and stable performance

After more than 100 years of development, lead-acid battery technology has been perfect, stability and reliability have been tested. Its working principle is based on the reversible electrochemical reaction of lead and sulfuric acid, the process is simple and clear, and engineers know its characteristics. From car start-up to communication base station backup power supply, lead-acid batteries continue to operate stably in a variety of complex environments. In the communication base station in the southern area of high temperature and high humidity, the lead-acid battery can adapt to the harsh climate and provide stable power for the equipment; In the cold northern winter, even if some electric vehicles use lead-acid batteries as auxiliary power, they can ensure the normal operation of the basic functions of the vehicle. In contrast, some new energy storage technologies, such as emerging solid-state batteries and flow batteries, although the theoretical performance is excellent, the technology is still in the optimization and improvement stage, and the practical application may face problems such as poor battery consistency and unstable life, and it is difficult to achieve a mature and stable state such as lead-acid batteries in the short term.

## Large current discharge: instant burst of powerful power

In scenarios where powerful energy needs to be released instantaneously, lead-acid batteries have full advantages. Car engine start moment, need up to hundreds of amps or even thousands of amps of current to drive the starter, lead-acid battery can easily, with its good large current discharge performance, so that the engine quickly ignition start. In the industrial field, some electric equipment such as forklifts and trucks that frequently start and stop also rely on the powerful instantaneous power output of lead-acid batteries. In the new energy storage technology, although some batteries have high energy density, they are not good at large current discharge, which can not meet such application scenarios where the demand for instantaneous power is extremely high. Lead-acid batteries rely on this unique skill to gain a firm foothold in specific fields and become an irreplaceable choice.

## Recycling system: Green closed loop sustainable development

With increasingly stringent environmental requirements, the recycling of energy storage technology has become an important consideration. A perfect and efficient recycling system has been established for lead-acid batteries. According to statistics, the global recovery rate of lead-acid batteries is as high as 90%. After the recycling of waste lead-acid batteries, the recycling of raw materials such as lead and sulfuric acid can be realized through professional processes, which greatly reduces the pollution to the environment and reduces the demand for new resources exploitation. In many developed countries, the mature recycling industry chain makes lead-acid batteries form a green closed loop from production, use to recycling. In contrast, some new energy storage technologies, due to the complexity of material composition, recycling technology is difficult, has not yet established a perfect recycling system, in terms of sustainable development, lead-acid batteries have seized the opportunity to lay a solid foundation for its long-term development.

Of course, lead-acid batteries are not perfect, and short boards such as low energy density and relatively short cycle life also exist. However, in this showdown between traditional and new energy storage, its significant advantages in cost, technology maturity, high-current discharge performance and recovery system make it still have a win in many application scenarios. With the continuous innovation of technology, lead-acid batteries are also continuing to evolve, and the future is expected to continue to write its own brilliant chapter in the energy storage market.
