The carbon nanotube (CNT)-based inner carbon host and an ultrathin outer amorphous carbon layer introduced at the SnO/SnO2 heterostructure had good elasticity and high electrical properties to prevent volume change and ensure fast Li-ion transport during cycling, respectively. Meanwhile, the SnO/SnO2 heterostructure comprising p-type SnO and n-type SnO2 facilitated further fast interfacial Liion transfer within the p-n SnO/SnO2 heterojunction anode via the acceleration effect induced by the built-in electric field (BEF). The resulting half cells LIBs consisting DCL@SnO/SnO2 anode shows a high reversible specific capacity of 902.1 mAh g(-1) after 500 cycles at a current density of 1400 mA g(-1). The specific capacity of 347.04 mAh g(-1) was still maintained even at a high current density of 10 000 mA g(-1). Moreover, the maximum energy and power density of 125 W kg(-1) and 200 Wh kg(-1), respectively, were achieved from the half cells LIC comprising DCL@SnO/SnO2 anode (LIC-DCL@SnO/SnO2).
