NOVELTY - The lithium ion secondary cell (1) has an anode (2), cathode (3), non-aqueous electrolyte and separator (4). The cathode contains cathode collector which support the mixture (A) containing cathode active material, electroconductive material and binder. The anode contains anode collector which support the mixture (B) containing anode active material, electroconductive material and binder. The anode and cathode have electric capacitance of 50-500 mAh/cm3. The mixture (B) has electrical resistivity of 0.1-1 ohm.cm.    USE - Lithium ion secondary cell for electric power storage used as power supply for portable machine such as mobile telephone, notebook computer, digital camera and small video camera.    ADVANTAGE - The lithium ion secondary cell is free from swelling of battery after charging and discharging characteristics, and has excellent battery capacity.    DETAILED DESCRIPTION - The lithium ion secondary cell has an anode, cathode, non-aqueous electrolyte and separator. The cathode contains cathode collector which support the mixture (A) containing cathode active material, electroconductive material and binder. The anode contains anode collector which support the mixture (B) containing anode active material, electroconductive material and binder. The anode and cathode have electric capacitance of 50-500 mAh/cm3. The mixture (B) has electrical resistivity of 0.1-1 ohm.cm. The cathode active material is surface amorphous graphite. The anode and cathode collector are metal porous material containing iron, stainless steel, nickel, copper and their alloy. The metal porous material is foaming nickel. The anode active material is olivine-type lithium-iron-phosphate (LiFePO4). The mixture (A and B) are high graphitized carbon fiber. The non-aqueous electrolyte further contains (gamma)-butyrolactone and (gamma)butyrolactone containing ethylene carbonate.
