Analytical Study of a Battery Charge Cycle

In order to improve the bromine storing capacity and hence the battery efficiency 

Until today the only available data obtained by direct sampling of a prototype battery system concerning mass flow of the complexing agents as well as the Br2 produced in both the aqueous and non-aqueous electrolyte phases have been gained by application of Raman spectroscopy [89, 90]. 

The most interesting results of a study of a real 12 V/i kWh zinc-flow battery (Powercell Lda.) with a charge capacity of 92 Ah are reviewed in Figs. 6 and 7. 

In order to improve the bromine-storing capacity and hence the battery efficiency of a zinc-flow cell, knowledge of the structure and consistency of the complex phase during the entire charge-discharge cycle is an essential requirement. 

The authors suggested testing of the application zinc-flow batteries with higher MEP MEM ratios. It should be noted that the results from a study of the mass flow in the aqueous parts of the system [87] correlated favorably with the findings described above.
