Our group applied the structurally stable channel material MoV0.41Te0.12O4 (MVT-M1) to the positive electrode of zinc-ion batteries. MVT-M1 has wide and stable six-membered ring (approximately 5Å) and seven-membered ring (approximately 6Å) tunnels, which are conducive to reversible Zn2+ intercalation and deintercalation during the recycling process, and are rich in redox centers (Mo, V, Te ), promote charge redistribution, thereby showing good performance in zinc-ion batteries. In addition, thanks to MVT-M1's excellent resistance to bombardment by high-energy electron beams, our group used a high-angle annular dark field scanning transmission electron microscope to directly observe the insertion and extraction process of Zn2+ in the tunnel at the atomic scale.
