Potassium ions have a higher negative electrode structure (2.93 V for K + /K, 2.58 V for Na + /Na) than sodium ions, resulting in increased battery life and fast energy [23]. Furthermore, the K + /K redox couple in propylene carbonate (PC) has a lower standard voltage than the Li + /Li and Na + /Na redox couples [24].
