摘要
Abstract 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 (MoS 3 ) on reduced graphene surface (denoted as MoS 3 ‐on‐rGO), which exhibits low strain and fast reaction kinetics for beyond‐lithium‐ions (Na + , K + , Zn 2+ ) storage is demonstrated. Benefiting from the low volume expansion and small sodiation strain of the MoS 3 ‐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, Zn 2+ batteries and hybrid supercapacitors, demonstrating its excellent application prospect.
