China scientists’ breakthrough flow battery hits 850 cycles, retains 99.95% capacity | With new organic molecules, the organic flow battery performed well for 600 cycles without a drop in capacity.
Chinese scientists develop organic molecules that are stable even when they come in contact with air in flow batteries.
A redox flow battery is a type of electrochemical cell in which electric current is generated by components dissolved in liquids stored on opposite sites of a membrane. A team led by Zhang Changkun and Li Xianfeng, both professors at the Dalian Institute of Chemical Physics, developed novel naphthalene-based derivatives with active hydroxyls and dimethylamine scaffolds that provide stability in air and can, therefore, be used in AOFBs. In addition to the performance improvements, the researchers also worked on the scalability of naphthalene derivatives production and achieved outputs of 11 pounds (five kg) per pot, the press release added.
