Facile Synthesis of Two-Dimensional Natural Vermiculite Films

To cope with this challenge, a two-dimensional (2D) vermiculite film has been successfully prepared by self-assembling expanded vermiculite nanosheets. The raw vermiculite mineral is first exfoliated to thin sheets of several atomic layers with about 1.2 nm interlayer channels by a thermal expansion and ionic exchanging treatment

Ceramic electrolytes hold application prospects in all-solid-state lithium batteries (ASSLB). However, the ionic conductivity of ceramic electrolytes is limited by their large thickness and intrinsic resistance. To cope with this challenge, a two-dimensional (2D) vermiculite film has been successfully prepared by self-assembling

Two-dimensional vermiculite separator for lithium sulfur batteries

A lamellar vermiculite separator assembled with exfoliation vermiculites is developed for lithium sulfur batteries. The vermiculite separator can simultaneously suppress the parasitic reactions induced by polysulfide intermediate shuttle, and prevent the short circuit by potential lithium dendrite penetration with the ultrahigh Young
