Revisiting the Origin of Sloping Capacity in Hard Carbon Negative Electrodes for Sodium-Ion Batteries
Abstract
Hard carbon is widely regarded as the most promising negative electrode material for sodiumion batteries due to its relatively high reversible capacity and characteristic low-voltage plateau behaviour. The sodium storage process in hard carbon is commonly divided into a high-voltage sloping region and a low-voltage plateau region. Whilst the plateau capacity has been extensively investigated, the physicochemical origin of the sloping capacity remains actively
