Tin-carbon-composite-nanoparticle layer electrodes were synthesized by the KMPP consisting of spherical Sn-nanoparticles and carbonaceous material with a particle size below 10 nm. Electrochemical measurements were performed in environmental temperatures of 0 °C, RT, 40 °C, 60 °C. It was shown that with elevating temperature the capacities and the degradation increase while the columbic efficiency decrease. The reasons for this temperature behavior can be explained by the Arrhenius equation, electrical and ionic conductivity of the electrolyte, the ohmic and the diffusion overpotentials.
