PURPOSE: An anode active matter composition is provided to have long life time characteristics. CONSTITUTION: An anode active matter composition is obtained as follows. LiNi, Co, a nickel chemical combination are mixed according to a predetermined mole ratio. A mixed matter is annealed at 400 to 600°C, thus a precursor powder of a quasi crystal state is obtained. The precursor powder of the quasi crystal state is re-mixed so as to be distributed lithium salt uniformly. The precursor powder of the quasi crystal state is annealed during 12 hours at 700 to 900°C, thus a crystalline active matter is obtained. A quasi metal 0.1 to 10 weight% is added to the anode active matter thus fabricated. |
