6 FAQs about [Problems with energy storage battery membranes]

How do cationic membranes affect battery permeability?

Diffusion of the V ions from one half-cell to the other leads to discharge of the battery and, thus, determines the energy storage time of the battery. Extensive research has shown that the cationic membranes are susceptible to V permeability due to their attraction of the V species.

Why are membrane-free batteries rarely investigated under actual flow conditions?

Membrane-free batteries have rarely been investigated under actual flow conditions because of the convective-mass-transport-induced disturbances at the liquid–liquid interface under flow conditions, which results in self-discharging and active material crossover 17, 31.

Do membrane-free batteries need a membrane?

Recently, immiscible electrolyte-based liquid–liquid biphasic systems have received significant attention for the construction of membrane-free batteries. The liquid–liquid interface of these biphasic systems separates the catholyte and anolyte and functions as a natural barrier, thus eliminating the need for a membrane.

Do thicker membranes improve battery safety?

On the other hand, thicker membranes are generally less prone to fail mechanically, which improves better battery safety. However, the internal resistance increases with increasing thickness, and the mechanical robustness on one hand must therefore be balanced against the ohmic resistance on the other.
