Abstract
In this work, mesoporous hard carbon materials were synthesized and modified by compositing a carbon coating and carbon nanotubes (CNTs), reducing the surface area and improving the conductivities without changing the microstructures of the anodes, which enhances the coulombic efficiencies and rate performances of sodium-ion batteries (SIBs).
摘要
在这项工作中，通过复合碳涂层和碳纳米管（CNT）合成并改性了介孔硬碳材料，在不改变阳极微观结构的情况下降低了表面积并提高了电导率，从而提高了钠离子电池（SIB）的库仑效率和倍率性能。
