DICP reporter learned yesterday from the Chinese Academy of Sciences, researchers led by Zhang Min independent Laptop Battery research group developed 2kW all vanadium flow storage batteries durability demonstration evaluation system, since July 6, 2007 model run since the beginning, is still without a failure, a continuous Run two years, the total running time of more than 17,500 hours to achieve charge / discharge cycle over 4,500 times. After testing, the battery module's energy conversion efficiency to find any attenuation. The results show that all vanadium flow storage batteries have excellent reliability and stability, which for its engineering and industrial development has laid a solid foundation.
After 9 years of technology accumulation, DICP flow energy storage battery in the theoretical research and application demonstration have achieved fruitful results. In 2006 and 2008, respectively, to develop China's first 10kW and 100kW vanadium redox flow battery energy storage system, respectively, through the Office of Liaoning Provincial Science and Technology appraisal, the Group believes that the technology is "the leading domestic and international advanced" level. In August 2008 with demonstrations in Tibet Solar Energy Research Center, in Tibet, a "solar photovoltaic power generation - Energy Storage Battery storage power flow," the joint application and demonstration of power supply system. Flow storage batteries has now completed the design and assembly, arrived in Lhasa, is working with the solar photovoltaic system for the FBI. In September 2008 for the national grid to provide a 100kW/200kWh vanadium redox flow battery energy storage system for battery and application Acer Aspire 2000 battery characteristics of the net inspection. In October 2008 with Bo Rong (Dalian) Industry Investment Co., Ltd. a joint venture set up a "melt in Dalian Branch Energy Storage Technology Development Co., Ltd.", specialized in engineering flow battery energy storage and industrial development.
Redox flow battery energy storage system as a cost-effective energy storage device has a broad application fields and market prospects. Including those for wind, solar and other renewable energy power generation systems to solve its power generation is not continuous instability characteristics; for the power system to regulate the client load balancing, to ensure stable operation of smart grid; charging stations for electric vehicles, electric vehicles to avoid the large current charging impact on the power grid; for high energy-consuming enterprises, Gu peak electricity use, reduce production costs; and communications applications in the telecommunications base stations, the state's important Acer BATCL32L battery sectors such as backup power plants. Flow battery energy storage technology development will bring huge social and economic benefits.
Vanadium redox flow battery energy storage through the positive and negative electrolyte solution in the activity of valence changes of vanadium ions to achieve electrical energy storage and release. Compared to other energy storage technologies, with output power and storage capacity can be independently designed and easy to meet different application needs; cycle life long; to the depth of discharge; energy conversion efficiency is high; Safety and Environmental Protection; low maintenance cost advantages, with strong technological competitiveness has become the storage Acer BATCL32 battery technology of choice for one of the technologies.
In a strong social development needs and a huge potential market-driven, the flow storage batteries for its own technological advantage received extensive attention, is ushering in a new period of vigorous development. But to achieve practical application and industrialization of many scientific issues and technical problems remain to be breakthrough, DICP is actively promoting the flow energy storage battery technology, engineering and industrialization process, in order to achieve national scale utilization of renewable energy and implement energy-saving policy to make a significant contribution to emission reduction.
