LITHIUM SECONDARY BATTERY WITH HIGH ENERGY DENSITY |
摘要 |
The present invention relates to electrodes for a lithium secondary battery with a high energy density and a secondary battery with a high energy density using the same. A negative electrode includes a material which can be alloyed with lithium alloy. A positive electrode is made of a transition metal oxide which can reversibly intercalate or deintercalate lithium. Here, the entire reversible lithium storage capacity of the positive electrode is greater than the capacity of lithium dischargeable from the positive electrode. Further, the present invention relates to electrodes for a lithium secondary battery in which metal lithium is coated on a negative electrode, a positive electrode, or both, a method of manufacturing the electrodes, and a lithium secondary battery including the electrodes. The lithium secondary battery of the present invention is excellent in safety because metal lithium does not remain after being activated and excellent in a capacity per unit weight. |
