In recent years, interest in the application and use of materials for supercapacitors for electric vehicles has grown significantly. The advantage of capacitor ceramics over other dielectric materials for producing supercapacitors is its environmental friendliness and high economic efficiency. This paper presents the results of a study of capacitor ceramics doped with Sn at different locations of the modifier (tin) in BaSnTiO3 and BaTiSnO3 crystal lattice. The influence of modifiers in low-temperature sol-gel synthesis was studied. The samples were annealed at 1000°C. The resulting phases were identified by X-ray phase analysis. Microscopic analysis was also performed.

This report examines the characteristics of powerful supercapacitors, which are used in electric vehicles to perform their driving dynamics, as well as to power starter motors of powerful internal combustion engines in large trucks, military vehicles and more. Main requirement for supercapacitors is tobe able to deliver a large amount of electricity for about ten seconds, and for very powerful motors (over 100 kW) – for up to 15 seconds. Various technological methods have been reported for supercapacitorsproduction, including the onedeveloped by the current authors, which is based on a ceramic dielectric with a high relative dielectric constant.
