Abstract
The article is devoted to the study of the electrochemical properties of coatings obtained from an anodically synthesized electrolyte containing a freshly obtained suspension of tin powder particles. The conducted studies have established that tin-tin powder composite coatings obtained from anodically synthesized electrolyte with a dispersed phase remaining in the electrolyte are promising anode materials of lithium-ion batteries with a specific capacity of 1000 – 1300 mAh/g. The high specific characteristics of the materials are due to the additional possibilities of intercalation of lithium into the intergranular space of the composite coating and the high diffusion coefficients of lithium into this space, amounting to 10-13 – 10-15 cm2/s and increasing with increasing stoichiometry of intercalates. Composite materials tin-tin powder remain operational at a temperature of minus 40 °C due to the phase transition of tin into the β-phase, which has a greater value of the crystal structure parameter.
Keywords: potentiometric methods, pulsed current mode, tin powder, composite electrodes, structure, electrodeposition, lithium intercalation, encapsulating shell, ethylene glycol
