ELECTRO ACTIVE MATERIAL FOR SECONDARY BATTERY, CONDUCTIVE COMPOSITION FOR SECONDARY BATTERY, CATHODE MATERIAL, CATHODE STRUCTURE AND SECONDARY BATTERY COMPRISING THE SAME, AND FABRICATING METHODS THEREOF

摘要

The present invention relates to an anode material for a secondary battery, a conductive composition for a secondary battery, a cathode material including the same, a cathode structure and a secondary battery including the same and a method for manufacturing the same. The present invention includes: silicon particles; and a non-crystalline surface layer formed on the surface of the silicon particles. According to the present invention, the structure of cathode comprises a composite of silicon particles and carbon or lithium ion solid electrolyte, and, since the oxygen contents of the silicon particles is low, thus the coagulation of the silicon particles are suppressed. Therefore, when using the structure of cathode to the cathode, a condensing device such as a lithium secondary battery is capable of having a high energy density, a high power density, and a longer charging-discharging cycle lifespan performance.
