Researchers from the University of Technology Sydney, the University of Manchester, Australian Synchrotron, Swinburne University of Technology and Australian National University have developed a new method to improve the lifespan of zinc-ion batteries that offer an alternative to lithium-ion technology for grid-scale storage.
The team focused on the cooperative Jahn-Teller effect, a phenomena that induces asymmetry in individual ions and solid-state lattices and are commonly observed in structures containing specific transition metals, such as copper and manganese. The scientists designed a two-dimensional (2D) manganese-oxide/graphene “superlattice” that triggers a unique lattice-wide strain mechanism. That strain helps the cathode resist breakdown during repeated cycling.
