<P>PROBLEM TO BE SOLVED: To satisfy needs as follows; in charging/discharging a lithium ion battery, a high current needs to be charged into a battery, or a high current needs to be discharged to outside, and for such charging/discharging electric conductivity of an electrode active material needs to be improved as well as charging/discharging operation needs to be driven by a simple voltage operation. <P>SOLUTION: A lithium ion battery is a battery having as an electrode active material a carbon obtained by baking a xylene formaldehyde resin precursor in an inert atmosphere at 550°C to 950°C and pulverizing it. An internal resistance of a carbon electrode active material of the battery is lower in charging/discharging than that of a synthetic graphite system electrode active material so that input and output of a high current associated with charging/discharging becomes possible, and charging/discharging can be linearly controlled by a voltage after determining a certain charging/discharging capacitance range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
