▎ 摘　　要

NOVELTY - Super-lattice material formed by self-assembly of titanium-cobalt-oxide nanosheets with a thickness of 1-2 nm and polydopamine-reduced graphene oxide (PDDA-rGO) aqueous phase, is claimed. USE - The material is useful in modifying lithium sulfur battery diaphragm (claimed), energy storage, electrocatalysis and other fields. ADVANTAGE - The material improves the performance of lithium-sulfur batteries with only an ultra-low areal loading of 0.079 mg/cm2. DETAILED DESCRIPTION - Super-lattice material i.e. Ti0.83Co0.1O2/rGO formed by self-assembly of titanium-cobalt-oxide (Ti0.83Co0.1O2) nanosheets with a thickness of 1-2 nm and polydopamine-reduced graphene oxide (PDDA-rGO) liquid phase, is claimed. An INDEPENDENT CLAIM is also included for preparing super-lattice material.
