Achieving high areal capacity current lithium-ion batteries (LIBs) become a significant challenge in fields of consumer electronics, vehicle electrification, and aerospace. One of the most important strategies to achieve high areal capacity is developing unique electrodes through a hybridization blueprint. Herein, we demonstrate the design of 3D self-supportive pseudocapacitance core-shell architecture electrode as high areal capacity anode for LIBs. The pseudocapacitive 1D−VN/2D−MoS₂ nanowires/nanosheets core/shell coated on free-standing 3D carbon fiber textile (CFT) (denoted CFT-VN@MoS₂) exhibit high areal capacity of 6.80 mAh cm⁻² at 0.5 mA cm⁻², attractive rate performance of 1.27 mAh cm⁻² at 17.0 mA cm⁻² as well as 80% capacitive contribution at 1.5 mV s⁻¹. The excellent storage performance of CFT-VN@MoS₂ over CFT-VN and CFT-MoS₂ anodes can be related to the synergistic effect of the dual pseudocapacitive storage mechanism of both VN and MoS₂ and tailored 3D nanoarchitecture design. This present work urges an appropriate approach to improve the areal capacity and rate capability of self-supporting electrodes and may also be applicable to other hybrids for LIBs and beyond.

实现高面积容量的当前锂离子电池（LIB）成为消费电子，车辆电气化和航空航天领域的重大挑战。实现高面容量的最重要策略之一是通过杂交蓝图开发独特的电极。在这里，我们演示了3D自支撑式伪电容核-壳结构电极作为LIB高面积容量阳极的设计。假电容1D-VN / 2D-MoS ₂纳米线/纳米片芯/壳包覆在独立式3D碳纤维织物（CFT）（表示为CFT-VN @ MoS ₂）上，在0.5 mA时显示出6.80 mAh cm ^-2的高面积容量cm ^-2，在17.0 mA cm时的吸引力速率性能为1.27 mAh cm ^-2在1.5 mV s ^{-1时具有−2}以及80％的电容贡献。CFT-VN @ MoS ₂优于CFT-VN和CFT-MoS ₂阳极的优异存储性能可能与VN和MoS ₂双重伪电容存储机制以及量身定制的3D纳米体系结构设计的协同效应有关。本工作促成一种适当的方法来改善自支撑电极的面积容量和倍率能力，并且还可能适用于LIBs或以后的其他混合动力汽车。
