Formation and study of thin-film lithium-ion batteries using CNT/silicon composite material as an anode

Abstract

An approach to the formation of new composite material of the anode electrode for lithium-ion batteries composed of carbon nanotubes (CNTs) synthesized on a substrate coated with a silicon layer has been studied. The dependence of the cyclicity and specific capacity of such a material on the geometric parameters of a CNT array has been studied. Using a CNT/silicon composite, the battery prototypes have been assembled and their characteristics and behavior during prolonged storage have been studied.
