Ultra-fast and facile preparation of uniform sulfur/graphene composites with microwave for lithium-sulfur batteries.

Lithium-sulfur batteries are one of the most promising energy storage systems due to their high energy density. Many efforts have been made to improve the electrochemical performance of lithium-sulfur batteries. However, the complex and time-consuming preparation process hinders their practical application.

A Simple and Highly Efficient Method toward High-Density Garnet-Type LLZTO Solid-State Electrolyte.

Garnet-type LiLaZrO (LLZO) is among the most attractive candidates for achieving solid-state lithium batteries. LLZO pellets with high density are preferred because of their potential to prevent dendritic Li growth and penetration. However, the presence of pores inside the LLZO electrolyte is inevitable if it is prepared by a traditional solid-state reaction.
