A method of making an electrode includes the step of mixing active material particles, radiation curable resin precursors, and electrically conductive particles to create an electrode precursor mixture. The electrode precursor mixture is electrostatically sprayed onto a current collector to provide an electrode preform. The electrode preform is heated and calendered to melt the resin precursor such that the resin precursor surrounds the active particles and electrically conductive particles. Radiation is applied to the electrode preform sufficient to cure the radiation curable resin precursors into resin.

A material with pine-branch like samarium oxide/graphene/sulfur gel structure, and a preparation method and use thereof. The material is reduced graphene oxide carrying pine-branch like samarium oxide on the surface to form a cross-linked gel structure, and sulfur is loaded on the gel structure. The preparation method includes: subjecting graphene oxide and a samarium salt to hydrothermal reduction to prepare a reduced graphene oxide/samarium precursor; under an inert atmosphere, thermolysing the reduced graphene oxide/samarium precursor to obtain a reduced graphene oxide/pine-branch like samarium oxide gel; and melting and diffusing the sulfur onto the reduced graphene oxide/pine-branch like samarium oxide gel. The material with pine-branch like samarium oxide/graphene/sulfur gel structure greatly improves the electrochemical performance of lithium-sulfur batteries.
