Two-phase interface hydrothermal synthesis of binder-free SnS₂/graphene flexible paper electrodes for high-performance Li-ion batteries.

ABSTRACT: Free-standing graphene-based composite paper electrodes with various active materials have attracted tremendous interest for next-generation lithium-ion batteries (LIBs) due to advantages such as their light weight, excellent mechanical flexibility, and superior electrochemical performance. However, despite its high theoretical energy density, SnS₂ is rather difficult to composite with the graphene paper, because conventional reduction procedures for graphene oxide (GO) induce either decomposition or oxidation of SnS₂. Herein, a novel solid/gas two-phase interface hydrothermal process is reported to fabricate flexible free-standing SnS₂/graphene nanocomposite papers (SGP) assisted by a reducing and stabilizing agent thioacetamide aqueous solution.
