Lead-acid batteries, with their own series of unique advantages, play a key role in this integration, and inject strong impetus into the steady development of the new energy industry.

In the global wave of actively promoting energy transformation and vigorously developing new energy industries, lead-acid batteries, a traditional energy storage device, are being integrated into them with a new attitude, opening a journey of cross-border integration with the new energy industry, and giving birth to a new trend of collaborative development. Lead-acid batteries, with their own series of unique advantages, play a key role in this integration, and inject strong impetus into the steady development of the new energy industry.

## Lead-acid batteries and photovoltaic industry: complementary advantages of the golden partner

As the main force in the field of new energy, solar photovoltaic power generation has developed rapidly in recent years. However, photovoltaic power generation is subject to light conditions and is intermittent and unstable. The addition of lead-acid batteries makes up for this shortage. In the distributed photovoltaic power station, when the light is sufficient during the day, the photovoltaic panel converts the solar energy into electricity, a part of it is used directly by the user, and the excess energy is stored in the lead-acid battery. In the night or cloudy days when the light is insufficient, the lead-acid battery releases the stored electric energy to ensure that the user continues to use electricity. Compared with other energy storage devices, lead-acid batteries have obvious cost advantages. According to market data, the cost of building a lead-acid battery energy storage system with the same energy storage capacity is only 40%-60% of that of some new lithium battery energy storage systems. This makes lead-acid batteries the preferred energy storage solution in small distributed photovoltaic projects with limited funds. Its mature technology also brings high reliability, in complex outdoor environments, lead-acid batteries can operate stably, reduce maintenance costs, extend the overall service life of the photovoltaic system, and promote the widespread popularity of the photovoltaic industry in civil, commercial and other fields.

## Lead-acid battery to help wind power consumption: stable power output guarantee

Wind power generation also faces the problem of unstable power generation, and the uncontrolled wind speed leads to large fluctuations in wind power output, which brings challenges to grid access. Lead-acid battery energy storage system can be installed in the wind farm, when the wind speed is too high, wind power output surplus, the excess energy will be stored; When the wind speed drops and the power generation is insufficient, the electric energy is released to supplement. The excellent high current discharge performance of lead-acid batteries is crucial in this process. When the wind power sudden change needs to be adjusted quickly, it can respond quickly, stabilize the output of electric energy, and avoid the impact on the grid. Moreover, the large-scale production technology of lead-acid batteries is mature, and the product consistency is high, which is convenient for large-scale deployment in wind farms. By integrating with the wind power industry, lead-acid batteries help improve the consumption rate of wind power, reduce the phenomenon of "wind curtailment", so that wind power, a clean energy, is more efficiently integrated into the power supply system, and promote the healthy development of wind power industry.

## The unique value of lead-acid batteries in the field of new energy vehicles

In the field of new energy vehicles, although lithium-ion batteries occupy a dominant position, lead-acid batteries still have an irreplaceable role in specific scenarios. For low-speed electric vehicles, such as elderly mobility scooters, scenic sightseeing vehicles, etc., lead-acid batteries have become the mainstream choice with their low cost and high safety. These vehicles travel at relatively low speeds and short mileage, and the battery energy density is not high, and the lead-acid battery just meets the demand. Its rich raw material resources and stable price greatly reduce the cost of vehicle manufacturing, making low-speed electric vehicles affordable and in line with the purchasing power of the majority of low-end consumers. At the same time, the lead-acid battery structure is simple, convenient maintenance, in the area of imperfect after-sales service system, this advantage is particularly prominent, to ensure the normal use of low-speed electric vehicles, to promote the wide application of new energy vehicles in the field of short-distance travel, and lithium-ion battery-driven high-speed electric vehicles to form a dislocation development, collaborative and complementary pattern.

## Cross-border integration promotes innovation in lead-acid battery technology

With the deep integration with the new energy industry, lead-acid batteries also usher in new opportunities for technological innovation. The diversified demand for energy storage equipment performance in the new energy industry has prompted enterprises to increase investment in research and development. In terms of materials, new lead alloy plates are developed to improve battery cycle life and charge and discharge efficiency; In the battery management system, intelligent technology is introduced to achieve accurate monitoring and control of battery status, and further improve the reliability and stability of lead-acid batteries. This technological innovation is not only conducive to the lead-acid battery to play a better role in the new energy industry, but also to expand its application boundaries in other fields, forming a virtuous cycle of industrial integration and development.

With the advantages of cost, technology, performance and other aspects, lead-acid batteries show strong vitality in the cross-border integration with the new energy industry. Through the coordinated development of photovoltaic, wind power, new energy vehicles and other segments, lead-acid batteries not only help the new energy industry to overcome development bottlenecks and achieve sustainable development, but also continue to upgrade and innovate in the process of integration, ushering in new development opportunities, and becoming an indispensable force in promoting the process of global energy transformation.
