Abstract
Layered electrode materials, positive electrodes, rechargeable zinc batteries, and methods are provided. A layered electrode material for use in a rechargeable zinc battery includes a plurality of active metal slab layers in a layered configuration. The active metal slab layer includes a plurality of redox active metal centers and a closely-packed anionic sublattice. A plurality of interlamellar spaces separate adjacent active metal slab layers in the layered configuration. The interlamellar space includes at least one pillar species. The layered electrode material has a combined average metal oxidation state in a range of +3 to +4 in an initial charged state. The layered electrode material accepts solvated zinc cations via intercalation into the interlamellar space upon reduction.
