Inside Front Cover: Carbon Neutralization, Volume 2, Issue 3, May 2023

Abstract

Inside front cover image: The ambitious goal of cabron neutralization requires the further development of fast energy storage devices like supercapacitors, while the severe self‐discharge of conventional electrochemical double‐layer capacitors has greatly limited their development. The recent emergence of conjugately configured supercapacitor has brought a new frontier for alleviating self‐discharge. In article number https://doi.org/10.1002/cnl2.55, The researchers explored how the carbon coating strategy, which has already been widely used to modify active materials to enhance conductivity and cycling stability, could introduce profound and complex influence to self‐discharge property for active materials specifically used for conjugatedly configured supercapacitors. The proposed conjugated configuration as well as the optimization strategy specifically for such device is expected to provide a general and powerful approach for alleviating self‐discharge.

Bio‐Inspired Electrodes with Rational Spatiotemporal Management for Lithium‐Ion Batteries

“…Additionally, carbon shells enhance conductivity and significantly reduce the charge transfer resistance of Si‐based anodes. [ 154 , 311 , 312 , 313 ] The double‐shelled hollow structures effectively tune the vigorous volume change, facilitates the formation of a highly stable SEI layer, shortens the electron/lithium‐ion transport distances and provides fast electron transport in the interconnected hollow structure. [ 314 ] Thus, a compact micron‐sized composite anode with a tight binding and double‐shell architecture possesses superior deformation resistance and electrical conductivity, contributing to excellent cycling stability and good rate capability in a thick electrode.…”
