    Lithium ion battery anode materials(silicon-based)
    To improve capacity and energy density of LIB, DAEJOO ELECTORNIC MATERIALS developed Si-based composite oxide materials showing the performances beyond the limit of traditional carbon anode materials. Compared to the limit of capacity of carbon anode 370mAh/g, it is able to realize around 4 times of carbon material capacity.
