Two fully conjugated covalent organic frameworks present high performance for both gas capture and Li ion storage, confirming their high potential in future Li–gas battery applications.
A modified Pechini sol–gel method was developed to synthesize three-dimensional pomegranate-like SbxBi1−x@C composites as anode materials for advanced potassium-ion batteries.
Due to the low cost, high element abundance and intrinsic safety, potassium-ion batteries (KIBs) have attracted a surge of interest in recent years. Here, 2D O- and S-terminated V2C MXene anode materials are designed to model high performance KIBs.
