Electrode material for non-aqueous electrolyte secondary cell and non-aqueous electrolyte secondary cell using the same |
摘要 |
An electrode material comprising a lithium-containing transition metal oxide having a spinel structure, characterized in that a part of the crystal structure of the metal oxide includes another spinel structure which is formed by the configurations of different metal elements combined which are able to form a spinel structure through a common oxygen configurations. The crystal phase of the metal oxide is stabilized by introduction of such a structure, and thus the metal oxide exhibits improved stability at a high temperature. A non-aqueous electrolyte secondary battery using the electrode material has improved storage stability at a high temperature and improved high temperature cycle characteristics, and thus keeps its capacity at a high rate even after a storage at a high temperature or after a high temperature cycle.
