NOVELTY - The apparatus has a winding part (104) by which a positive electrode (101) and a negative electrode (102) are wound on sides of a separator (103). A connection part (105) consists of a part in which the positive electrode and the negative electrode are extended to exterior of the winding part. The winding part is connected with the connection part. The apparatus is provided with desired flexibility when the connection part is curved or bent. The positive electrode is formed in a positive electrode electrical power collector and a positive mix layer that is formed by graphene.    USE - Electrical storage apparatus e.g. electrical storage element such as sheet-like electrical storage element e.g. non-aqueous lithium secondary battery, for use as an uninterruptible power supply of non-commercial electric equipment e.g. installation type illuminating device provided in a ceiling, separate type air-conditioner, electric refrigerator-freezer, high-frequency heating device such as microwave oven and electric rice cooker, thin-shaped mobile telephone, wristband type display apparatus, TV broadcast reception display apparatus and notebook-type personal computer for business use, industrial use and for military use. Can also be used for a table top type illuminating device provided in a side wall, floor and a window, integrated air-conditioner, transceiver, portable wireless apparatus, vehicle e.g. track-laying vehicle, hybrid vehicle and plug-in hybrid car, handheld game machine, toy, calculator, portable information terminal, electronic organizer, electronic book, electronic translating machine, voice input device, video camera, digital still camera, electric shaver, electric washing machine, smoke sensor and a dialyzer.    ADVANTAGE - The winding part can be densely positioned for high capacitation, so that a number of windings of a winding structure can be increased. The positive mix layer can be formed on a positive electrode electrical power collector such that electroconductivity of a positive electrode active material layer is increased and oxidation graphene is mutually distributed, so that need for aggregating positive electrode active material contained in a slurry can be minimized and increase of particle size of the positive electrode active material can be reduced, thus making easy movement of electron in the positive electrode active material, and hence improving electroconductivity of the positive electrode active material layer. The graphene is contained in the negative electrode to maintain bind of negative electrode active material even if the volume of the negative electrode active material carries out expansion or contraction with charging/discharging, so that durability of the battery can be improved by using the negative electrode and charging capacity of the negative electrode can be enhanced, thus preventing pulverization of a silicon whisker and disintegration of the negative mix layer and improving cycling characteristics.
