Summary: With the increasing demand for electrochemical energy storage, commercial lithium-ion and metal battery systems have been developed. The separator, an essential component of batteries, plays a crucial role in determining their electrochemical performance. However, conventional polymer separators have limitations that hinder the development of electric vehicle power batteries. Advanced graphene-based materials have emerged as a solution to these challenges. Incorporating advanced graphene-based materials into the separator of batteries can overcome these issues and enhance their capacity, stability, and safety. This review provides an overview of the preparation and applications of graphene-based materials in different types of batteries, and outlines future research directions in this field.

Supercapacitors are reliable energy storage devices with rapid charging rate, high power density, simple setup, and good stability. The performance of supercapacitors is significantly influenced by electrode materials. Vanadium pentoxide, with mixed oxidation states, eco-friendliness, low cost, high capacitance, and high energy density, is a potential electroactive material for supercapacitors. However, its poor conductivity and low cyclic stability are major drawbacks that affect its electrochemical properties. Various strategies to overcome these limitations have been reviewed in this article.
