摘要：
We successfully synthesized sulfur particles with a bowl-like structure and wrapped them in graphene oxide (GO) via a simple method. The GO-wrapped bowl-like sulfur composite (GO-BS) with void space inside was used as cathode material of Li-S batteries, which realized the protection of active material and tolerance of volumetric expansion.
