LITHIUM BATTERY AND POWER VEHICLE

The lithium battery comprises a positive electrode plate, a negative electrode plate and an electrolyte. The positive electrode plate comprises a positive electrode current collector and a positive electrode material layer provided on the surface of at least one side of the positive electrode current collector. A positive electrode active material of the positive electrode material layer comprises LiFeMnPO and a lithium transition metal oxide. The mass of LiFeMnPO accounts for X% of the total mass of LiFeMnPO and the lithium transition metal oxide, 0< X
