Disintegrated carbon nanofibers derived from plasma treatment for highly stable sodium metal batteries
Carbon-based materials have been widely used in anodes for sodium metal batteries (SMBs). Surface modification of carbon-based materials is an effective method to improve the de-embedding behavior of sodium metal, which can increase the battery life, whereas SMBs need simpler and more efficient modification methods for practical-grade application. In this paper, novel disintegrated carbon nanofibers (D-CNFs) with rough surfaces were obtained by plasma treatment. D-CNFs exhibited highly reversible sodium deposition characteristics and were able to operate at a low polarization potential of 0.023 V for 800 h. The coulombic efficiency of the D-CNFs was stabilized above 97% after the third cycle. This excellent electrochemical performance is attributed to the disintegration of CNFs as a result of the plasma treatment. The CNFs expose richer vacancies, providing more active sites for sodium metal deposition. This implies that the prepared D-CNFs have better sodium storage properties. Meanwhile, this surface modification facilitates the further application of carbon-based materials in SMBs.
期刊介绍:
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
