The lead-carbon battery energy storage system was officially put into demonstration operation in Dalian

The widespread use of renewable energy such as wind and solar energy has always been plagued by technological bottlenecks such as discontinuity, instability, and difficulty in regulation of power generation. How to match the corresponding energy storage system to ensure the stable output of electricity.

A few days ago, the lead-carbon battery energy storage system jointly developed by the research team led by Lixianfeng researcher and Zhanghuamin researcher of the Dalian Institute of Energy Storage Technology Research Department of the Chinese Academy of Sciences and Baoding Fengfan Group Co., Ltd.. The Dalian Institute of Chemical Physics of the Chinese Academy of Sciences officially put into demonstration operation.

Lead carbon battery technology is a new type of electrochemical energy storage technology developed based on supercapacitor and lead-acid battery technology. It has the advantages of high safety, low cost, and high discharge power, and can achieve 100 % battery recovery. The full life cycle environmental load is very low. The potential for development is enormous. The long-life lead-carbon storage can effectively solve the storage problem of solar power generation by combining battery with solar power generation system.

It is understood that the application of the lead-carbon battery energy storage demonstration system mainly provides high-quality and stable lighting and electricity for Zhouweiludeng and landscape lights in the Dalian Chemical Energy Institute Building 1 and Energy Building 2 of the Chinese Academy of Sciences, and its successful operation will lay the foundation for the engineering and industrialization of the system.

With the depletion of resources and the deterioration of the environment, as well as the growing maturity of renewable and clean energy generation technologies such as solar and wind energy, renewable and clean energy has gradually been upgraded from auxiliary to dominant energy sources. However, renewable energy power generation has the disadvantages of discontinuity, instability, and difficulty in regulation, and it is difficult to ensure the stable output of electricity.

In December 2015, the Dalian Chemical Institute of the Chinese Academy of Sciences and China Shipyard Heavy Industry and Wind Sailing Co., Ltd. jointly established the "Advanced Battery Technology Joint Research and Development Center" to cooperate in the research and development of advanced lead-carbon battery industrialization technology. At present, the key technical difficulties in salinization of lead-carbon batteries have been solved. The cycle life of lead-carbon batteries used in photovoltaic energy storage systems was increased to more than four times that of traditional lead-acid batteries. The batch trial production of 12V/38Ah products on the production line was completed, and new materials with independent intellectual property rights were formed in advanced lead-carbon storage batteries. And new product production technology.

On this basis, the Research Department of Energy Storage Technology and Research of Dalian Institute of Technology of the Chinese Academy of Sciences has also developed a number of new technologies to successfully develop lead-carbon long-life batteries, which provide guarantees for the conversion of clean energy such as solar energy and wind energy into usable and output stable energy.
