Why do batteries lose coulombic efficiency?Ions could flow directly between electrodes through internal pathways, bypassing an external circuit. These losses reducing coulombic efficiency in batteries, can occur when a battery is in operation, or when a battery self-discharges in storage.

Why is the polysulfide/iodide flow battery a low coulombic efficiency?The polysulfide/iodide flow battery is a promising candidate for large-scale energy storage systems, but the technology suffers from a notably low Coulombic efficiency. This phenomenon arises because the crossover of hydroxide ions triggers the disproportionation reaction of I 3– ions in the posolyte.
