POSITIVE-ELECTRODE ACTIVE MATERIAL FOR ELEVATION OF OUTPUT IN LOW VOLTAGE AND LITHIUM SECONDARY BATTERY INCLUDING THEM |
摘要 |
A lithium secondary battery having improved output characteristics is provided. A high voltage mixed positive electrode active material has an even profile without causing a rapid voltage drop over the entire SOC area by improving a rapid voltage drop phenomenon occurring due to the difference between the operation voltages of mixed lithium transition metal oxides, and improves output characteristics at a low voltage. The lithium secondary battery includes the mixed positive electrode active material. In particular, the lithium secondary battery can sufficiently satisfy the required conditions such as output characteristics, capacity, stability, and the like, when it is used as a power source of a midsize or large device such as an electric vehicle. |
