Tannic acid-derived carbon-coated Bi nanodiscs for high-performance sodium-ion batteries

Abstract

A simple route was applied to obtain Bi nanodiscs embedded into tannic acid (TA) derived carbon (Bi@TAC) by calcining Bi2O3@TA precursors. As a result, the Bi@TAC electrode showed an impressive rate capability (a current density ranging from 0.2 to 10 A g−1 with 95% capacity retention) and a long-term cycling performance (414.8 mA h g−1 after 10 000 cycles at 5 A g−1).
