| abstract |
The present invention relates to a mixed lithium silicate, wherein the mixed silicate is represented by the following formula: Li 2 M II I (1x) M III x SiO 4 (OH) x (I), 0 ≦ x ≦ 1, and M is Fe, Co, Mn, or Ni. They are substantially spherical, unattached particles, 400-600 nm in size, and their structure is characterized by belonging to space group Pna2 1 or space group Pccn. Silicates are obtained from the precursors in an aqueous solution by centrifugation. They can be used as active materials for electrodes of electrochemical devices. |
