recently, low-carbon clean energy research institute of Beijing gao cooperation with tsinghua university completed & other; High energy density of the liquid organic electrochemical active material flow throughout the battery &; Research results in a recent issue of the American chemical society sponsored the journal ACSAppliedEnergyMaterials, and have been reported as a magazine cover key SRC = 620) makesmallpic( 620年,1800年) ; SRC =, wide attention from society.

the large-scale energy storage ( Or grid energy storage) Technology is to improve the rate of renewable energy grid and popularize application of key technologies, and the development of energy and the Internet, the distributed power generation, power frequency modulation, off-grid power supply, security key enabling technology in the field of standby power supply, etc. The low-carbon clean energy research institute of Beijing gao cooperation with tsinghua university completed & other; High energy density of the liquid organic electrochemical active material flow throughout the battery &; Research results for the first time was proposed based on the liquid organic flow battery of active material and the theory of theory of high energy density, high power density and good reactivity, is currently one of the most promising large-scale energy storage technology, compared with the traditional flow battery, with good safety, power and capacity can be independent design, long storage time, big output power, energy storage advantages of large capacity and easy to extend.

low carbon development of high power density flow density flow battery pile photos and test results. A typical kilowatt flow battery power density cm - more than 500 mW 2, higher than with traditional flow battery 2 - level Three times, the realization of pile material of miniaturization and efficient, with obvious low cost advantage.

at the same time, the flow of the positive and negative battery the rich raw material source of 2, 5 -, respectively Tertiary butyl - 2 1 - Methoxy - 4 - （ 2 - A oxygen ethoxy) Benzene and 2 - Methyl diphenyl ketone. Open circuit voltage of battery to 2. 97 V, 1 - higher than traditional flow batteries 1. Five times the energy density theory Wh 223 L? 1, is the traditional flow theory of battery energy density ( 50 L Wh ? 1) More than four times. Experiments show that the active flow battery the poles of the active material has excellent electrochemical performance and good cycle stability, current efficiency reached 95%, the energy efficiency reached 70%. The study from the perspective of a new preliminary exploration success to improve the direction of the flow battery energy density, for research and development of a new generation of flow battery technology has important inspiration significance.
