The Acid/Base Flow Battery is an innovative and sustainable process to store electrical energy in the form of pH and salinity gradients via electrodialytic reversible techniques. Two electromembrane processes are involved: Bipolar Membrane Electrodialysis during the charge phase and its opposite, Bipolar...
A high-performance acid-base blend ion exchange membrane is designed and prepared for vanadium flow battery (VFB) application. Through transferring H + -SPEEK to Na + -SPEEK, the compatibility of hydrophilic sulfonated poly(ether ether ketone) (SPEEK) and polybenzimidazole (PBI) is improved. A ...
Extensive cycling of the soluble lead flow battery has revealed unexpected problems with the reduction of lead dioxide at the positive electrode during discharge. This has led to a more detailed study of the PbO 2/Pb 2+ couple in methanesulfonic acid. The variation of the phase composition (XRD...

Fig. 13.Cross-sectional view of a flooded lead-acid battery[26]. The most common battery rating is the ampere hour (Ah) rating. This is aunit of measurementfor battery capacity obtained by multiplying a current flow in amperes by the time in hours of discharge. Manufacturers use differentdi...
A novel lead acid flow battery based on the Pb(II)/Pb and PbO2/Pb(II) couples in aqueous methanesulfonic acid was described. 论述了可溶性Pb2+电解液在电池充放电过程中的平衡关系及其对平衡产生影响的各种因素,正负极电沉积过程的特点,添加剂对铅和二氧化铅电沉积的影响及充放电的特性,概述了铅酸液流...
State of charge (SOC) determination is an increasingly important issue in battery technology. In addition to the immediate display of the remaining battery capacity to the user, precise knowledge of SOC exerts additional control over the charging/discharging process which in turn reduces the risk of...
