Knowledge: There are three types of Li-Ion cells on current market based on chemistry of cathode materials. Please see the table below to see advantage and disadvantage of each type cell. Among of them, LiCoO2 series Li-Ion cell has the highest energy density. LiFePO4 is the most safe but lower energy density and LiMnO4 series cell is safer and higher enegidensity, which may be more suitable for Electric Vehicle
