, Suqian Times Energy Storage is a high-tech enterprise focusing on the R & D and production of water-based organic liquid flow energy storage batteries, with core technologies such as water-based organic liquid flow batteries and ion exchange membranes. At present, the first phase of the company's production line with an annual output of 2 GWh has been put into operation, and the whole industry chain has been realized to produce water-based organic flow batteries.
Under the dual effects of industrial policy guidance and market demand-driven, the new energy storage industry has developed rapidly. In the past two years, the scale of flow batteries in the energy storage industry and the heat of the capital market have increased significantly. According to
Bloomberg New Energy Finance, by the end of August 2023, the installed capacity of flow batteries in China has reached 220 MW/865 MWh, and the scale of reserve projects has reached 5G W/18 GWh; by 2025, China will deploy up to 4GW flow batteries.
Aqueous organic flow energy storage battery is one of the new flow battery technologies in recent years, which is a battery technology using water-soluble organic matter as electrolyte, with the advantages of long life, safe operation, environmental friendliness and wide range of sources. Xiang Zhanbo, founder
of Suqian Times Energy Storage, introduced that Suqian Times Energy Storage is an enterprise with the whole industrial chain layout of water system organic flow battery. At present, the company has realized the self-production of core raw materials and components such as electrolyte, ion exchange membrane, bipolar plate, runner plate and special pipeline. In terms of energy efficiency, the energy efficiency of the company's water-based organic liquid flow energy storage battery on the DC side of the stack has reached more than 85%, and the comprehensive energy efficiency of the battery has reached more than 70%. On October 15
this year, the first set of megawatt water-based organic flow batteries produced by Suqian Times Energy Storage was put into production, formally entering the stage of large-scale production. The key technologies of
aqueous organic flow battery technology are electrolyte and ion exchange membrane, which directly determine the performance and life of the battery.
In terms of electrolyte, the electrolyte of aqueous organic liquid flow energy storage battery is dissolved in pure water or salt water by organic synthetic substances, which has the characteristics of intrinsic safety, and there is no risk of fire or explosion. Yang Zhengjin, chief scientist
of Suqian Times Energy Storage, introduced that the water-based organic liquid flow energy storage battery developed and manufactured by the company can use neutral NaCl aqueous solution as supporting electrolyte, which is inherently safe, environmentally friendly and has no risk of combustion and explosion. At the same time, the electrolyte is neutral and non-corrosive, has a wide range of sources, is not restricted by resources, and has relatively lower cost. Anion exchange membrane (AEM) is another core material of
aqueous organic flow energy storage battery. This material should not only block the active material between the positive and negative electrodes to prevent short circuit, but also ensure the efficient passage of ions in the process of charging and discharging to reduce losses.
Yang Zhengjin introduced that since its establishment, Suqian Times Energy Storage has cooperated with Xu Tongwen Team of China University of Science and Technology to develop AEM technology, which fills the gap in the application of AEM in large-scale energy storage flow batteries in China. Compared with imported AEM, the production cost is about 80% lower than import price.
At present, Suqian Times Energy Storage has built the first large-width AEM production line, and mass production offline, the membrane can also be used in water electrolysis hydrogen, hydrogen fuel cells and other fields. The company is working with the University of Science and Technology of China to develop the next generation of AEM, which can achieve higher energy conversion efficiency to achieve shorter production cycle and lower cost.
In terms of applicable scenarios, water-based organic liquid flow energy storage battery is a technology suitable for long-term energy storage. The water system organic liquid flow energy storage battery has lower self-discharge, smaller battery loss, and more than 10,000 charge-discharge cycles in its life cycle. Its application scenarios mainly include wind and solar distribution and storage, frequency modulation/peak shaving with coal-fired power plants, frequency modulation/peak shaving on the grid side, peak shaving and valley filling on the user side, etc. Xiang Zhanfeng, deputy general manager
of Suqian Times Energy Storage, told 36 Carbon that due to the technical advantages of decoupling power (stack) and capacity (liquid storage tank) of organic liquid flow energy storage batteries in water system, the electrolyte is safe, stable and easy to store and transport, and can be stored independently to achieve high safety, large-scale and long-term energy storage and ensure the safety of energy output. In terms of
customers, the company's current customers are mainly large enterprises with large demand for energy and electricity, such as electricity, petroleum, chemical industry and transportation, with a total order size of more than 1 GWh. In terms of
future planning, the company will continue to cooperate with Professor Yang Zhengjin of China University of Science and Technology, Professor Song Jiangxuan of Xi'an Jiaotong University and Professor Cao Jianyu of Changzhou University to develop the next generation of electrolytes and other core materials for organic liquid flow batteries in water system, which is expected to achieve a breakthrough in single-molecule multi-electron transfer. And that stable circulation of the electrolyte for 50,000 time is realized, so that the energy density of the battery is further improve, the cost of the electrolyte is reduced, and the service life of the battery is prolonged. In terms of
team, Suqian Times Energy Storage members come from top universities and research institutes at home and abroad, with more than 70 R & D personnel and more than 40 core patents. At present, the company has established a complete technology system for production, teaching and research with the top universities in the field of liquid flow batteries in China, such as the University of Science and Technology of China, Xi'an Jiaotong University and Changzhou University.
