Abstract:
PURPOSE: An electrode active material is provided to offer a lithium battery with excellent storage stability, lifetime, and high voltage performance at high temperature by regularly arranging pores. CONSTITUTION: An electrode active material(10) with a nanostructure comprises a core(12) which includes one or more from metal or metal oxides capable of emitting and absorbing lithium ions; and a crystalline carbon thin film(14) which is formed on at least a part of the core surface. The electrode active material includes pores(16) and walls among the pores. The pore includes one or more of SnO2 and MoO2. The thickness of the crystalline carbon thin film is 2nm or less. The specific surface area of the electrode active material is 50-250 m^2/g.
