Membranes are a crucial component of the battery as they affect the ohmic resistance and the power density of the cells, as well as the depth-of-discharge and the lifetime and thus, crucially affect the levelised cost of storage of the battery.
Moreover, the membranes can serve as separators in conventional battery systems, as well as electrodes and electrolytes in advancing research. Regulating the membrane structure and selecting appropriate membrane materials are significant for realizing a high energy density, excellent rate capability, and safety of LRBs.
As the vital roles such as electrodes, interlayers, separators, and electrolytes in the battery systems, regulating the membrane porous structures and selecting appropriate membrane materials are significant for realizing high energy density, excellent rate capability, and long cycling stability of lithium rechargeable batteries (LRBs).
Additionally, high ion conductivity and high ion selectivity are always preferred for the membrane, which can provide the battery with high efficiency (coulombic efficiency (CE) and voltage efficiency (VE)).
The first studies on the permeation of active species through the membrane in operating vanadium flow batteries were done by Xi et al. (2008) [ 99] and Sun et al. (2010) [ 100] and featured concentration monitoring of the reservoirs as a function of time using a dialysis cell.
Once a clear understanding of the correlation between membrane apparent properties (such as conductivity, permselectivity and permeability) and cell capacity retention and performance is established through validated numerical models, development of a battery with optimized operating parameters will be made possible.
After exposure to NaOH solution (6 mol L −1) at 50 °C for 8 days, the non-ionic membrane can still provide an outstanding battery performance for 120 cycles at 80 mA cm −2, revealing the high stability of the designed membrane in alkaline media. Regardless, the ionic conductivity of the membrane and the VE of the battery remain to be improved.
