Abstract
Composite SiO/C anodes for lithium-ion batteries (LIB) obtained by carbonization of silicon monoxide with fluorocarbon were investigated. Preliminary modification of the initial silicon monoxide was carried out by disproportionation and subsequent treatment in hydrofluoric acid. The study of the elemental composition of modified SiO and the electrochemical performance of composite anodes made from it showed that the oxygen content in the oxide matrix played a decisive role in changing their behavior. Depletion of it with oxygen as a result of treatment in HF had a beneficial effect, leading to higher stability of the electrodes during cycling, an increase in their capacity, coulombic efficiency and rate capability.
期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
