| 摘要 |
The present invention provides, as a lithium-containing transition metal oxide, a substance which is given by the chemical compositional formula Li4M5O12 (M = Cr, Co, or Zr) and has a spinel-type crystal structure. Provided is a lithium ion secondary cell having a positive electrode configured from a lithium-containing transition metal oxide which has a spinel-type crystal structure and has the chemical compositional formula Li4M5O12 (M = Cr or Co). The present invention further provides a lithium ion secondary cell having a negative electrode configured from a lithium-containing transition metal oxide which has a spinel-type crystal structure and has the chemical compositional formula Li4M5O12 (M = Zr). |
