The serious volume change and corresponding severe sluggish reaction kinetics of germanium phosphide (GeP) during the discharge/charge cyclic procedure impeded the practical application of GeP anode. Structural design is an effective strategy that elaborately solves the problems above but still remains to be explored. In this study, a facile hybrid crosslinking strategy using CNTs and PAN pyrolysis carbon on surface coating was innovatively proposed. In this way, the coated conductive carbon networks not only ensured the fast ion/electron transport rate in the electrode, but more importantly, restrained the severe volumetric change of GeP within the confined networks. Electrochemical performance measurement and reaction kinetics was carried out to identify the positive effects of hybrid crosslinking. Compared with the pure GeP rods, amorphous carbon (AC) or CNTs coated GeP rods, the CNTs/AC hybrid coated materials greatly improved the electronic conductivity and Li⁺ diffusion coefficient (D_Li+), enabling the GeP/CNTs/AC anode features high reverSiBle lithium storage capacity and good cycling stability. When served as anode electrode of lithium ion battery (LiB), the reverSiBle capacity for GeP/CNTs/AC were 571.5 mAh g⁻¹ and 822.9 mAh g⁻¹ at 100^th cycle under 0.1 A g⁻¹ at the voltage range of 1-1.5 V and 0-3 V vs. Li⁺/Li, respectively. Besides, the GeP/CNTs/AC can be also used as anode for sodium-ion battery (SiB). This study offers a facile and highly effective approach that advances the GeP closer to practical application for LiB/SiB with high reversible capacity.

磷化锗（GeP）在放电/充电循环过程中严重的体积变化和相应的严重缓慢的反应动力学阻碍了GeP负极的实际应用。结构设计是精心解决上述问题的有效策略，但仍有待探索。在这项研究中，创新性地提出了一种在表面涂层上使用 CNT 和 PAN 热解碳的简便混合交联策略。这样，涂覆的导电碳网络不仅确保了电极中快速的离子/电子传输速率，更重要的是，抑制了受限网络内 GeP 的剧烈体积变化。进行电化学性能测量和反应动力学以确定混合交联的积极影响。与纯 GeP 棒相比，⁺扩散系数 (D _Li+ )，使 GeP/CNTs/AC 负极具有高可逆锂存储容量和良好的循环稳定性。当用作锂离子电池（LiB）的阳极时，GeP/CNTs/AC 的可逆容量在 100^次循环、0.1 A g ^-1和 1 的电压范围内分别为 571.5 mAh g ^-1和 822.9 mAh g ^-1 -1.5 V 和 0-3 V vs. Li ⁺ /Li，分别。此外，GeP/CNTs/AC 还可用作钠离子电池（SiB）的负极。这项研究提供了一种简便高效的方法，使 GeP 更接近于具有高可逆容量的 LiB/SiB 的实际应用。
