Effect of synthesis conditions and doping of mesoporous tin dioxide on the properties of electrodes for rechargeable lithium-ion batteries based on it

Abstract

We have conducted a study of the effect of synthesis conditions and doping of tin dioxide-based mesoporous materials on the electrochemical characteristics of electrodes for rechargeable lithium-ion batteries based on them. The mesoporous materials were synthesized in the presence of templates (the cationic surfactant CTABr and the nonionic Pluronic F127) in aqueous and ethanol media; In2O3 and SiO2 were used as the dopants. We have studied the characteristic features of the effect of the synthesis conditions on the thermal stability, surface area, and pore volume for the materials obtained. The initial capacity of the lithium-ion battery based on the microporous material containing SiO2 was 507 mA·h·g –1 , where the capacity decreased by 11% after 30 charge/discharge cycles.
