Lead-carbon battery technology is a new electrochemical energy storage technology based on supercapacitor and lead-acid battery technology. It has the advantages of high security, low cost, high discharge power, and can achieve 100% battery recovery. Its life cycle environmental load is very low, and its development potential is huge.
The wide application of renewable energy, such as wind energy and solar energy, has always been hampered by technical bottlenecks such as discontinuity, instability and difficulty in regulation and control of power generation. How to match the energy storage system to ensure the stable output of power? Recently, the lead-carbon battery energy storage system developed by Li Xianfeng and Zhang Huamin of Dalian Institute of Chemicals, Chinese Academy of Sciences and Baoding Sailing Group Co., Ltd. has been put into demonstration operation in Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
Lead-carbon battery technology is a new electrochemical energy storage technology based on supercapacitor and lead-acid battery technology. It has the advantages of high security, low cost, high discharge power, and can achieve 100% battery recovery. Its life cycle environmental load is very low, and its development potential is huge. The combination of long-life lead-carbon energy storage battery and solar power generation system can effectively solve the storage problem of solar power generation. It is understood that the lead-carbon battery energy storage application demonstration system mainly provides high-quality and stable lighting power for the street lights and landscape lights around Energy Building 1 and Energy Building 2 of Dalian Institute of Chemical Sciences, and its successful operation will lay a foundation for the engineering and industrialization of the system.
In China, traditional power generation methods such as thermal power and coal power are mostly used. With the depletion of resources and the deterioration of the environment, as well as the maturation of renewable clean energy generation technologies such as solar energy and wind energy, renewable clean energy is gradually upgraded from auxiliary energy to dominant energy. However, renewable energy generation is discontinuous and unstable. It is difficult to ensure the stable output of electricity.
In December 2015, Dalian Institute of Chemicals of Chinese Academy of Sciences and China Shipping Heavy Industry Wind Sail Co., Ltd. jointly constructed the "Advanced Battery Technology Joint Research and Development Center" and cooperated in the research and development of advanced lead-carbon battery industrialization technology. At present, the key technical problems of sulfation of lead-carbon batteries have been solved, and lead-carbon power for photovoltaic energy storage system has been used. The cycle life of the battery has been increased to more than four times of that of the traditional lead-acid battery. The 12V/38Ah product has been trial-produced in batches on the production line. New materials and new product production technologies with independent intellectual property rights have been formed in the advanced energy storage lead-carbon battery.
On this basis, the Department of Energy Storage Technology Research, Dalian Institute of Chemicals, Chinese Academy of Sciences, has developed a number of new technologies and successfully developed lead-carbon long-life batteries, which provide a guarantee for the conversion of clean energy such as solar energy and wind energy into stable energy that can be used and exported.
