Hollow Carbon Nanospheres: Syntheses and Applications for Post Lithium Ion Batteries

Abstract

Hollow Carbon Nanospheres (HCNs) have found broad applications in different kinds of electrochemical storage devices. The characteristic hollow structure endowed the carbon electrode materials good reaction kinetics, high mechanical reliance against structural deformation, and powerful capability in loading functional materials, which makes themselves of particularly interest in different energy storage systems. In this review, we summarized the recent progresses on the research of HCNs with focus on the synthetic strategies and the corresponding applications as high-performance electrode materials in the post lithium ion batteries systems. Besides the widely-implemented template routes, those self-templated routes based on chemical design of the polymeric precursors will also be introduced. Efforts are directed to the shape evolution mechanism during the synthesis, and the control capability of different methodologies on the key structural features of HCNs including shape, compositions, and architectures will also be highlighted. Furthermore, we introduced the representative applications of the prepared HCNs in post lithium ion batteries such as lithium sulfur batteries, sodium ion batteries, and potassium ion batteries. We try to correlate the battery performance with the structural characters of HCNs so as to not only make good use of the advantage in shape control, but also to facilitate the understanding on the charge storage mechanism in the newly-emerged technologies.
