Abstract
The present invention relates to a lithium transition metal phosphate including nano rod-like FeP crystals, a method of preparing the same, and a lithium secondary battery manufactured by using the lithium transition metal phosphate. According to the present invention, a lithium transition metal phosphate including nano rod-like FeP crystals may be provided, thereby enhancing high rate capability and low-temperature properties of a lithium secondary battery prepared by using the same. Further, the whole or a part of an airflow direction in a firing furnace may be controlled to be in a direction opposite to a proceeding direction of a fired raw material by adjusting the exhaust conditions in the firing process, thereby providing a method of preparing a lithium transition metal phosphate, in which the nano rod-like FeP crystals are reproducibly included.
