The　idea　of　forming　van　der　Waals　(vdW)　heterostructures　by　integrating　various　two-dimensional　materials　breaks　the　limitation　of　the　restricted　properties　of　single　material　systems.　In　this　work,　the　electronic　structure　modulation,　stability,　entire　stress　response　and　the　Li　adsorption　properties　of　heterostructures　by　combining　blue　phosphorene　(BlueP)　and　MS2　(M　=　Nb,　Ta)　together　were　systematically　investigated　using　first　principles　calculations　based　on　vdW　corrected　density　functional　theory.　We　revealed　that　BlueP/MS,　vdW　heterostructures　possess　good　structural　stability　with　negative　formation　energy,　enhanced　electrical　conductivity,　improved　mechanical　flexibility　(ultimate　strain　＞17%)　and　high-capacity　(528.257　mAhg(-1)　for　BlueP/NbS2).　The　results　suggest　that　BlueP/NbS2　and　BlueP/TaS2　heterostructures　are　ideal　candidates　used　as　promising　flexible　electrode　for　high　recycling　rate　and　portable　lithium-ion　batteries,　which　satisfy　the　requirement　of　next-generation　flexible　energy　storage　and　conversion　devices.
