Experiment investigation of physical principles of high-speed composite functional films ands coatings deposition for electrode materials of energy sources. While conducting investigation, composite functional films and coatings for electrode materials of energy sources were produced using high-speed deposition at different process conditions. The structure formation features of composite functional films and coatings and their operation properties were investigated using contemporary methods of metallographic and electrochemical analysis. Of a great importance are optimum operation conditions, when films and coatings with rational microstructure, phase composition and structure constituents, with specific mass and surface, width and porosity are formed. Such films and coatings provide high operational properties of new electrode materials for contemporary energy sources. Basic parameters of technique of high-speed composite functional films and coatings deposition for electrode materials of energy sources were analyzed under laboratory conditions and pilot set of thin (50 mkm in width) battery with new electrode materials was produced for use in energy sources for microsystem apparatus. The comparison of absolute discharge capacity, specific energy and operating capability (number of charge-discharge cycles) of cognate batteries of well known trade marks produced with the same initial parameters: mass - 3.2 g, width - 50 mkm, surface 2 cm2 and discharge voltage (2.7 V) shows that the battery has higher operation characteristics with the same discharge voltage, in particular: discharge capacity - 220 mA/h, specific energy - 165 Wth/kg and operative capacity - 1000 charge-discharge cycles. The same characteristics of the well known trademark batteries: discharge capacity - 150 mA/h, specific energy - 127 Wth/kg and operative capacity - 800 charge-discharge cycles. Thus, the technique of high-speed deposition, used to produce composite functional films and coatings for electrode materials, is effective and perspective for electrode materials production for energy sources. Here, discharge capacity of the produced battery is 1.47 times higher then in other batteries, specific energy - is 1.3 times, operative capacity - is 1.25 times higher.
