摘要： Disclosed is a battery system for a secondary battery including a blended cathode material, and an apparatus and method for managing a secondary battery having a blended cathode material. The blended cathode material includes at least a first cathode material and a second cathode material. The first and second cathode materials have different operating voltage ranges. When the secondary battery comes to an idle state or a no-load state, the battery system detects a voltage relaxation occurring by the transfer of operating ions between the first and second cathode materials.

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.
