The proton exchange membrane (PEM) is a pivotal component in VRFBs, exerting a profound influence on battery efficiency and economic viability. Sulfonated poly(ether ether ketone) (SPEEK) membranes have garnered considerable attention as promising PEM candidates for VRFBs, due to their simple structure, straightforward synthesis, superior thermal and mechanical stability, cost-effectiveness, and amenability for modification. However, the large-scale application of SPEEK membranes in VRFBs is impeded by the inherent tradeoff between proton conductivity and vanadium ions permeability. The degree of sulfonation in SPEEK membranes is a critical parameter influencing their performance, as increased sulfonation improves proton conductivity but also augments ions permeability and membrane swelling simultaneously, compromising both membrane and battery performance. Addressing these limitations requires innovative strategies, such as structural regulation, functionalization, surface modification, and composite structure to enhance SPEEK membrane performance. In this review, we examine the recent research progress in the development of SPEEK membranes for VRFBs, encompassing recent advancements in optimizing their structure-performance relationship and chemical stability.

Therefore, it is crucial to develop a technology that can balance the trade-off relationship between battery degradation and reduced charging time. This research offers a model-based optimization methodology for charging strategies to control the battery-charging time and lithium plating at low temperatures. A dynamic programming algorithm that guarantees a global optimum is used as an optimization method. To formulate the optimization problem for dynamic programming (DP), the electrochemical model of the battery was converted to a control-oriented model with model reduction methods. To overcome the high computational burden of DP, we developed a good fidelity model including single-particle model with electrolyte (SPMe), thermal model, and plating model with a small number of states. The conscious factor was defined as a weighting factor between the two costs of charging time and lithium plating thickness, and the algorithm was performed at various conscious factors and ambient temperature conditions. The optimization result was verified by simulating the optimized charging profile of the algorithm using a full electrochemical model. The final result was analyzed and discussed using Pareto frontier and sensitivity analysis. In all the optimizations performed, a cost reduction of at least 7 % and up to 57 % was achieved compared to conventional 1C-rate constant-current-constant-voltage (CCCV) charging strategy.
