“…Theoretical calculation suggests that partial Group IVA and VA metals, as well as their compounds (e.g., oxides, sulfides, and selenides), are capable of delivering high capacities by forming Na-rich intermetallic compounds such as Na 3 Sb and Na 3 Bi through a combination of conversion and alloying reaction mechanisms. Among them, bismuth oxide (Bi 2 O 3 ) has attracted considerable attention due to its high theoretical capacity (669.8 mAh g –1 ), nearly two times higher than that of bismuth (Bi) (385 mAh g –1 ) . Furthermore, Bi 2 O 3 also has outstanding pros such as environmental friendliness, abundant sources, and relatively low cost .…”

“…Based on the power-law equation between the peak current (i) and the sweep rate (v): i = av b , 47,48 the value of b can be obtained using the following equation: log(i) = b log(v) + log(a). 49,50 The b value can be determined from the slope of the log(i) − log(v) plot and judges the capacitive or diffusioncontrolled mechanisms during lithium storage. 51 The b values This journal is © The Royal Society of Chemistry 2022 37 the capacitive contribution can be estimated.…”

“…[ 2,6–10 ] Among the aforementioned anode materials, alloy‐typed metal anodes (e.g., metallic Sb) show potential use in PIBs due to their superior metallic conductivity, large theoretical capacity (e.g., the theoretical capacity of Sb is 660 mAh g −1 for M 3 Sb, M = K), and high volumetric density (Sb: 6.7 g cm −3 ). [ 11–14 ] However, the huge volume expansion and severe pulverization of alloy‐typed metal anodes during the potassiation and depotassiation processes result in a sharp decrease in capacity. The general strategy addresses the issues to downsize the active materials to nano sizes and make composites with elastic carbon materials.…”
