Carbon- and transition metal-based matrixes as self-supportive anodes for high areal capacity lithium ion batteries

Abstract

Achieving high areal capacity is a challenge for current lithium-ion battery (LIB) systems to consolidate and expand the electric transportation and grid storage more economically and sustainably demands for high areal capacity self-supportive anode and cathode materials. Among the anode materials, carbon-based and transition metal-based matrixes have attracted research activities because they can be directly used as high-areal-capacity anode materials for LIBs upon further modifications. However, less attention were focus on the significant progress, current opinions and future challenges of these LIB-based anode materials. Herein, this opinion reviews the development of high-areal-capacity anode materials for LIBs, taking carbon- and transition metal matrixes as a case study. The prospects and directional guidance of the self-supportive carbon- and transition metal-based materials for the development of LIBs and the scientific issues are also presented.
