Dalian Institute of Chemical Physics (DICP) of Chinese Academy of Sciences (CAS) has developed via structure design a type of highly ordered mesoporous carbon (OMC) cathode material to make high-power density zinc-bromine flow batteries, reported the Xinhua-run cnstock.com Friday.
According to CAS, energy efficiency of a single zinc-bromine flow battery made with the DICP-developed highly OMC cathode materials exceeds 80 percent, marking hence the past low-power density bottleneck barring development of zinc-bromine flow batteries. As Shanghai Securities News reported, zinc-bromine flow batteries theoretically feature high-power density but low electrolyte cost, and its electric energy density is 3-5 times of lead-acid batteries'.
Backed on the prevailing home production of battery parts, the new breakthrough in materials for producing zinc-bromine flow batteries is good for development of China's storage cell industry.
