Peculiarities of sulfur electroreduction on the graphite electrode of lithium-ionic batteries

The additive into electrolyte SO2 allowing to realize the intercalation of lithium ions into spectral-pure graphite is shown in the work given. The monolayer of SO2 restoration products possessing the properties of solid inter phase electrolyte is formed on the material given. The formation of the surface layer requires 160±15 mA·h/g.

Electrochemical properties of activated carbon in alkaline electrolyte

We have studied the capacitance and kinetic properties of nanoporous carbon material which was obtained from wood. The maximum radius pore distribution of the investigated material was 1.37 nm. The data from X-ray scattering and electrochemical impedance spectroscopy was used to investigate the influence of porous structure change and electronic structure of activated carbon material on the mechanism and kinetics of charge-discharge at 7.6m KOH solution.
