Fluoride ion exchange in non-critical core material to achieve a breakthrough film under the premise of self-developed Chinese Academy of Sciences DICP 2kW all vanadium flow storage batteries have been successfully achieved as of last week, 10,000 charge / discharge cycles, the energy efficiency of the battery module is not apparent attenuation. This development will greatly push forward China's wind, solar and other renewable energy sources generalizable.
Dahua completed this achievement is the second after Japan's Sumitomo Corporation, the world's second breakthrough million charge and discharge cycle durability test examination of all vanadium flow battery energy storage system. glue gun The results show that the battery has excellent reliability and durability, is expected to achieve engineering and industrial development. Dahua the energy storage battery research team after nearly ten years of accumulation and innovation,glue stick energy storage battery systems in the flow of key materials, structural design, sealing technology, have made a number of significant results. Among them, ion exchange membrane is the key to the core flow battery energy storage materials.
It is understood that foreign commercial ion exchange membrane with good stability and durability, but the ion selectivity is poor, expensive, can not meet industry requirements. Dahua are from the practical, industrial requirements, the research has been developed with independent intellectual property rights, high-performance, low cost of new non-fluorinated ion exchange membrane materials, optimized performance and durability of the ongoing investigation. Up to now, the battery technology has been applied for a full set of 48 patents, of which 2 international patents, has authorized 13 to form a more complete system of independent intellectual property rights, research and development ability and technology in a leading position both at home and abroad. Rapid assessment of the durability of the current battery test system continues to run.
So far, all vanadium flow storage batteries is the only international success over 3 years by the wind power practical application and demonstration of the MW grid level above the electrochemical energy storage system, proved to be most suitable for smoothing the output of wind energy storage energy technology. High efficiency, low cost, safe and reliable storage of large-scale flow battery technology to further promote the development of wind, solar and other renewable energy applications and the popularity of smart grid will play an important role in the building. The current flow of energy storage battery industry chain has not yet fully formed, the liquid storage batteries cost is still relatively high. DICP energy storage technology with the Dalian Development Co., Ltd. Raycom work closely to carry out flow storage batteries electrolyte solution, ion exchange, the industrialization of the core material film technology platform development, has been formed in vanadium electrolyte solution when the 300 MW and 5 million square meters of carbon bipolar plate production capacity of plastic.
