摘要：

Novel composite anode materials were prepared for use in lithium-ion batteries. The composite material formation involved coating of powdered substrates (graphite-, or silicon-based), thus modifying their surface properties and cycling performance. Applying an additional surface coating resulted in the production of composites with enhanced stability in the practical lithium-ion battery environments. Coin cell cycling, as well as full 7Ah prismatic cell cycling, and impedance spectroscopy methods were used to evaluate the electrochemical properties of coated materials.
