| 英文摘要 | Silicon suboxide (SiOx) is considered a promising substitute for silicon (Si) anode materials in lithium-ion batteries due to its high specific capacity (>2200 mAh g鈭?) and improved cycling performance. However, its volume expansion (鈭?00%) and low conductivity cannot be ignored. Here, inspired by earbuds, we design and mass synthesize (240 g h鈭?) the earbuds-like three-dimensional SiOx nanonetworks (3D-SiOx NNs) by a radio-frequency thermal plasma (RF-plasma) system. The spray drying technology is used to further accelerate the winding of 3D-SiOx NNs to prepare micron-sized multi-hierarchical earbuds-ball-like SiOx/C (E-SiOx/C) with enhanced elasticity and high tap density. As anodes, E-SiOx/C exhibits the high gravimetric/volumetric specific capacity of 1790 m Ah g鈭?/1137 m Ah cm鈭? and excellent rate cycling performance (1480 m Ah g鈭? at 2.0 A g鈭? for 700 cycles). In addition, full battery constructed with LiNi0.5Co0.2Mn0.3O2 cathode exhibit high gravimetric energy density of 530.9 Wh kg鈭? and impressive cycling performance (513.9 Wh kg鈭? for 100 cycles), manifesting great promise for the application of high-performance batteries. 漏 2022 Elsevier Ltd |
