Abstract

Hard carbon is considered as the most prospective anode material for sodium ion batteries. However, the loss of plateau capacities at high rates, arising from large electrochemical polarization, causes rapid degradation in the rate performances of batteries. In this work, we found that the plateau capacities of hard carbon at high rates could be significantly enhanced in ether-based electrolytes.
