Abstract

Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) are prospective candidates for large-scale energy storage systems cause of their abundant resources. However, unsatisfactory rate and cycling performance of carbon-based anodes present a bottleneck for the applications of SIBs/PIBs due t...
