Lead-acid batteries, this traditional energy storage technology, under the east wind of policy support, show a vigorous development potential, and a grand development blueprint is slowly unfolding.

In the wave of global energy transformation, energy storage technology, as a key support for balancing energy supply and demand and improving energy utilization efficiency, is ushering in unprecedented development opportunities. Lead-acid batteries, this traditional energy storage technology, under the east wind of policy support, show a vigorous development potential, and a grand development blueprint is slowly unfolding.

Policy orientation: a strong booster for the development of lead-acid battery energy storage

In recent years, governments have introduced a series of policies aimed at promoting the development of the energy storage industry, lead-acid battery energy storage with its own characteristics, has become one of the key areas of policy support. From the national level, many countries have incorporated energy storage into the strategic planning of energy development, and clearly put forward the target of energy storage installed capacity, which provides a solid policy basis for the expansion of the lead-acid battery energy storage market. For example, in the "14th Five-Year Plan" energy planning, China attaches great importance to the energy storage industry, not only to set up special funds to support the research and development and application demonstration of energy storage technology, but also to open up green channels for energy storage to participate in the power auxiliary service market in the power system reform policy. These policies and measures have directly stimulated the large-scale application of lead-acid battery energy storage in the power grid side and the user side.

At the local level, local governments have formulated more detailed support policies in combination with their own energy structure and development needs. In some areas with rich new energy resources but poor grid stability, enterprises are encouraged to use lead-acid battery energy storage systems through subsidies, preferential electricity prices and other means to smooth the volatility of new energy generation and ensure reliable power supply. This top-down policy system, from research and development, production, application to market operation, escorts the development of lead-acid battery energy storage in an all-round way.

 Technological innovation: the upgrading of lead-acid battery energy storage

The injection of funds and resources brought about by policy support has greatly promoted the innovation of lead-acid battery energy storage technology. On the one hand, in the material development, researchers focused on the development of new lead alloys, by adding specific trace elements, significantly improve the corrosion resistance and electrical conductivity of the plate. The application of the new lead-calcium alloy plate has extended the cycle life of the lead-acid battery by 20%-30% and effectively reduced the long-term use cost. At the same time, the electrolyte formula is also continuously optimized, the combination of high-purity sulfuric acid and new additives improves the charging and discharging efficiency of the battery, and in some application scenarios, the charging and discharging efficiency can reach more than 90%.

On the other hand, in terms of battery management systems (BMS), policy-guided technological innovation has been fruitful. With the help of the Internet of Things, big data and artificial intelligence technology, the advanced BMS system can accurately monitor the voltage, current, temperature and other parameters of the lead-acid battery in real time, carry out intelligent charge and discharge control according to the actual state of the battery, avoid overcharge and overdischarge phenomenon, and further ensure the safe and stable operation of the battery. These technological innovations have made lead-acid battery energy storage achieve a qualitative leap in performance, so that it can maintain an advantage in competition with other energy storage technologies.

 Application development: multiple scenarios of lead-acid battery energy storage landing

The incentive of the policy promotes the acceleration of lead-acid battery energy storage in multiple scenarios. On the power grid side, lead-acid battery energy storage systems play a key role as "power buffers". In the face of the intermittenity of new energy generation and the imbalance of peak and trough of electricity consumption, lead-acid battery energy storage can store electric energy when there is a surplus of electricity, release electric energy when there is a peak of electricity consumption, effectively alleviate the pressure of the power grid, and improve the stability and reliability of the power grid. In some small power grids in remote areas, the application of lead-acid battery energy storage system has greatly reduced the loss caused by long-distance transmission and ensured the normal electricity consumption of local residents.

On the user side, lead-acid battery energy storage also shows broad application prospects. For industrial users, the use of peak-valley electricity price difference, in the trough period to store low-cost electricity, peak time to use stored electricity, can greatly reduce the cost of electricity. In a data center, lead-acid battery storage is used as the backup power supply to provide stable power when the mains is interrupted, ensuring data security and normal device operation. In distributed photovoltaic power generation projects, lead-acid battery energy storage and photovoltaic panels are used together to achieve self-use and surplus power storage, improve the rate of energy self-sufficiency, and reduce the dependence on the grid.

 Industrial ecological construction: the coordinated development pattern of lead-acid battery energy storage

With policy support, the lead-acid battery energy storage industry ecology is gradually improving, forming a good pattern of coordinated development. Upstream and downstream enterprises in the industrial chain have worked closely under the guidance of policies, from lead mining, lead-acid battery production and manufacturing, to energy storage system integration, installation and commissioning and operation and maintenance services, all aspects have been strong development. Large lead-acid battery manufacturers with policy advantages, continue to expand the scale of production, improve product quality, through technological innovation to achieve industrial upgrading; At the same time, a large number of small and medium-sized enterprises focus on segmented areas, such as battery parts manufacturing, energy storage system software research and development, etc., to inject vitality into the development of the industry.

Industry-university-research cooperation has also become increasingly close under the promotion of policies. With rich scientific research resources, universities and scientific research institutions continue to make efforts in the research of leading-edge technology of lead-acid battery energy storage, and provide technical support and innovative ideas for enterprises; Enterprises provide platforms and funds for the transformation of scientific research results, accelerating the process of new technologies from the laboratory to the market. The construction of this industrial ecology has not only enhanced the overall competitiveness of the lead-acid battery energy storage industry, but also driven the development of related supporting industries, created a large number of jobs, and injected strong impetus into economic development and energy transformation.
