Facile electrostatic assembly of Si@MXene superstructures for enhanced lithium-ion storage.

Silicon (Si) has attracted much attention as anode materials for next-generation lithium-ion batteries (LIBs) due to its high theoretical capacity. To improve the electrical conductivity, it is critically important to realize the uniform distribution of Si nanoparticles (NPs) onto conductive substrates such as graphene and MXene. Herein, a simple and effective strategy through facile electrostatic assembly was reported, in which Si NPs can adhere onto few-layer MXene (TiC) nanosheets uniformly to afford Si@MXene superstructures.

A Novel Electro-Thermal Laminated Ceramic with Carbon-Based Layer.

A novel electro-thermal laminated ceramic composed of ceramic tile, carbon-based layer, dielectric layer, and foaming ceramic layer was designed and prepared by tape casting. The surface temperature achieved at an applied voltage of 10 V by the laminated ceramics was 40.3 °C when the thickness of carbon-based suspension was 1.
