Active substance for lithium secondary battery |
| abstract |
A lithium secondary battery-use active matter containing a material capable of electrochemically desorbing and inserting Li, and having a metallic iron gra de in the material of less than 5 ppm; and a lithium secondary battery having this active mattter. An iron grade in the material of less than 5 ppm can ke ep a capacity maintaining factor within a high-value range after specified cycl es to improve the performance of a lithium secondary battery. |
