Beyond-lithium-ion storage devices are promising alternatives to lithium-ion storage devices for low-cost and large-scale applications. Nowadays, the most of high-capacity electrodes are crystal materials. However, these crystal materials with intrinsic anisotropy feature generally suffer from lattice strain and structure pulverization during the electrochemical process. Herein, a 2D heterostructure of amorphous molybdenum sulfide (MoS3) on reduced graphene surface (denoted as MoS3-on-rGO), which exhibits low strain and fast reaction kinetics for beyond-lithium-ions (Na+, K+, Zn2+) storage is demonstrated. Benefiting from the low volume expansion and small sodiation strain of the MoS3-on-rGO, it displays ultralong cycling performance of 40 000 cycles at 10 A g−1 for sodium-ion batteries. Furthermore, the as-constructed 2D heterostructure also delivers superior electrochemical performance when used in Na+ full batteries, solid-state sodium batteries, K+ batteries, Zn2+ batteries and hybrid supercapacitors, demonstrating its excellent application prospect.

通过结构工程利用 MoS3 阳极的体积膨胀实现锂基可充电电池以外的高性能
超锂离子存储设备是用于低成本和大规模应用的锂离子存储设备的有前途的替代品。目前，大容量电极大多是晶体材料。然而，这些具有固有各向异性特征的晶体材料在电化学过程中通常会受到晶格应变和结构粉碎的影响。在此，还原石墨烯表面（表示为 MoS 3 -on-rGO ）上无定形硫化钼（MoS 3）的二维异质结构，其对锂离子（Na +，K +，Zn 2+ ) 存储演示。受益于 MoS 3的低体积膨胀和小钠化应变-on-rGO，它显示了钠离子电池在 10 A g -1下 40 000 次循环的超长循环性能。此外，所构建的二维异质结构在用于 Na +全电池、固态钠电池、K +电池、Zn 2+电池和混合超级电容器时也具有优异的电化学性能，展示了其优异的应用前景。
