Appropriate methods for evaluating the efficiency and capacitive behavior

The energy efficiency is remarkably more sensitive to the maximum applied potential than the coulombic efficiency. According to Ref. [16], the low η E ≈ 50% at 1.6 V for the KI system could be due to a blockage of the hydrogen adsorption sites by the iodide reaction products (iodine and iodates), leading to irreversible di-hydrogen evolution.
