Application of different carbon-based transition metal oxide composite materials in lithium-ion batteries

Abstract

• This article introduces the composite mechanism of transition metal oxides and different carbon bases, and analyzes their advantages and disadvantages. • Secondly, we analyzed the role of carbon-based in composite materials. In addition, we discussed the influence of different carbon bases on the lithium storage capacity of composite materials. • Finally, we combined the same transition metal oxide with different carbon bases to compare the lithium storage capabilities of the composite materials. Transition metal oxides (TMOs) have high theoretical specific capacity and excellent safety performance, and have been widely used in lithium ion batteries (LIBS). Today, research on transition metal oxides has not been interrupted. However, in practical applications, transition metal oxides still have the disadvantages of severe volume expansion and poor cycle stability. After continuous exploration, researchers have found that combining transition metal oxides with carbon matrix can solve this problem well. Therefore, this article reviews the latest developments in transition metal oxide carbon-based (Porous carbon-based, Biological carbon-based, Graphene carbon-based and MXene carbon-based) composite materials for lithium-ion battery anode materials. In addition, we analyzed the current challenges of composite materials research and put forward our own views. Finally, the future development direction of composite materials in the field of energy storage is prospected.
