文摘

A dense and hybrid coating is fabricated on separator for long life Li-S Battery. The coating contains Li4Ti5O12 nanospheres embedded in graphene layers. The coating combines physical barrier with chemical adsorption for polysulfides. A fast lithium ion transport is achieved by Li4Ti5O12 nanospheres.
