“…The selection of electrode materials is of great importance since the electrochemical performance of LIBs relies heavily on the electrode properties. Carbon-based materials (e.g., graphite) are usually used as anode materials for LIBs because of their low cost, high abundance and outstanding kinetics [2,3]. However, graphite suffers great danger from the formation of lithium dendrite during the overcharge process owing to its low Li-intercalation potential (0.2V vs.…”

The catalysis role of boric acid at 800 °C is investigated in the synthesis of hard carbon from cotton. X‐ray diffraction analysis shows that d002 decreases and the size of the carbon crystal increases, which can only be realized at a higher temperature. Boron atoms are mainly combined on the surface layer of the particle. The specific capacity of the sample with B:C = 2.5 at 30, 1500 mA g−1 increases from 381.0 and 149.7 mAh g−1 (B:C = 0) to 526.8 and 196.6 mAh g−1, respectively. It is attributed not only to the plateau around 0.1 V, which results from the intercalation mechanism between graphite layers, but also to the storage mechanism of micropores. The capacity retention in the 200th cycle at 300 mA g−1 is improved from 88.5% to 94.1%. Therefore, the carbonization process of cotton is accelerated, and the catalysis function of boric acid proves to be workable. These improvements are partially resulting from the enlargement and regular stacking of carbon layers, which can accommodate more lithium ions. As boron atoms can occupy the defect vacancy points and order, large carbon layers are formed because of the electron deficiency property and fast transfer speed of boron atoms.
