| Abstract: | The 18650 lithium-ion secondary battery is prepared with spinel LiMn2O4 cathode material, and major factors affecting lithium-ion secondary battery's discharge performance under big currents are analyzed, including tab, electrode and electrolyte. Another 18650 high power lithium-ion secondary battery is prepared with innovative cathode material LiMnxNiyCozO2, which presents superior performance. The battery endures continuous discharge under 10C and quick charge under 8C and presents excellent cycling and storage performance. The development of 18650 high power lithium-ion secondary battery provides the experimental references for high power lithium-ion secondary battery for hybrid electric vehicle (HEV). |
