Red phosphorus (RP) has recently been considered as an anode material for sodium-ion batteries owing to its high theoretical capacity (2596 mA h g⁻¹). Even though it possesses high capacity, it has the major drawback of low electronic conductivity and severe volume expansion during charging/discharging. Electrode materials with multichannel RP nanoporous (MRPN) architectures have been prepared via a facile solvothermal method. These anode active materials are in the range of 50–100 nm. The MRPN-3 shows an improved discharge capacity of 1814 mA h g⁻¹ after 100 cycles at a current density of 200 mA g⁻¹. Furthermore, it exhibits an admirable performance at a high current density, providing excellent long-term cyclability. In this paper, we show that electrode materials with hollow nanoporous architectures offer several advantages, such as providing an efficient electron/ion transport network, buffering the volume expansion of RP nanoparticles, and enabling superior kinetics of efficient sodium-ion storage.

由于红磷（RP）的理论容量高（2596 mA hg ^-1），最近已被视为钠离子电池的负极材料。即使具有高容量，它也具有主要缺点，即电子电导率低，在充电/放电过程中体积膨胀严重。已通过简便的溶剂热法制备了具有多通道RP纳米孔（MRPN）结构的电极材料。这些负极活性物质的范围是50–100 nm。所述MRPN-3示出了1814毫安汞柱的改进的放电容量^-1 100次循环后在200毫安g的电流密度^-1。此外，它在高电流密度下表现出令人钦佩的性能，提供了出色的长期循环能力。在本文中，我们显示具有空心纳米孔结构的电极材料具有多个优点，例如提供有效的电子/离子传输网络，缓冲RP纳米颗粒的体积膨胀以及实现高效钠离子存储的优异动力学。
