Abstract:
PURPOSE: A three dimensional shape battery is applied to an electronic device varying with the inner shape thereof. CONSTITUTION: A three dimensional shape battery includes a cell structure including a first electrode layer, a second electrode layer, and a separator. The cell structure includes two or more pattern parts (11) with different sizes from each other and a connection part (21) which is formed between the pattern parts and connects the pattern part. The connection part has a bent or folded structure. The pattern part has a laminated structure laminated and facing each other. Each area of the pattern parts is gradually changed in the lamination direction of the pattern parts.

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.
