Often the evaluation of energy storage systems which use non-aqueous media requires the use of three-electrode electrochemical cells that employ a stable and reliable reference electrode. The existence of such a reference electrode is a non-trivial matter which has led to extensive misuse and misreporting across the field of battery research. This commentary highlights the current challenges in non-aqueous referencing which are commonly overlooked and offers best practices for acknowledging and accounting for such challenges when reporting data which heavily relies on having accurate reference potentials.
