摘要 |
A lithium secondary battery exhibiting low temperature output characteristics is provided. The lithium secondary battery of the present invention includes a current collector 12, and an active material layer 14 which is supported on the current collector 12 and contains active material particles 30 and electrically conductive material 16. The active material particles 30 each have a shell composed of a lithium transition metal oxide, a hollow part formed in the shell, and a through hole penetrating the shell. The electrically conductive material 16 contained in the active material layer 14 are arranged both in the hollow part of the active material particles and between the active material particles 30. |
