| 摘要 |
The present invention relates to an anode active material containing the lithium manganese phosphate according to the following Chemical Formula 1: <Chemical Formula 1> LiMn-_(1-x)M_xPO_4 In the formula, element M is at least one of Co and Fe and x is 0.01 to 0.7. The anode active material according to the present invention can store an increased amount of lithium, and thus can improve battery performance. In addition, the lithium secondary battery or the hybrid capacitor including the anode active material has a voltage curve that shows a linear shape which has a constant inclination during charging and discharging. Accordingly, state of charge (SOC) prediction is possible, advantages can be realized in terms of remaining capacity prediction or the like, and thus the application to electric cars or electric power storage devices can be highly advantageous. |
