Synthesis of metal oxide nanocomposites from self-assembled block copolymer templates as cathode materials for all-solid-state lithium batteries

Self-assembled structures are useful for fabrication of nanostructures as a sustainable process with minimum energy consumption. Alternately stacked layers on a nanometre scale are produced by adsorption process denoted as layer by layer process, however, shape is limited in layers and chemical composition is also limited. Superlattice structures are produced by sputtering or self-assembly process using nanoparticles. But the construction of three-dimensional ordered inorganic nanocomposite structures remains a great challenge. All-solid-state lithium batteries (LiBs) are attracting much attention as innovative devices for upsized safety secondary batteries with high energy density. However, bulk-type all-solid-state LiBs face a number of hurdles, particularly the construction of an electrochemically favourable interface between the solid Li electrolytes and the active materials. In this study, we synthesised inorganic nanocomposite cathode materials by using self-assembled block copolymers (BCPs) as temp...
