China develops all-iron flow battery electrolyte, claims 6,000 cycles and up to 80 times lower material cost
Researchers at the Chinese Academy of Sciences say they have developed an electrolyte for an all-iron flow battery that shows little performance degradation after more than 6,000 charge-discharge cycles. They argue raw materials could be up to 80 times cheaper than lithium-based batteries. The study focuses on improving long-term stability by reducing side reactions, active material loss and crossover. The work remains at the laboratory stage, with no pilot or commercialization timetable disclosed.
