POWDER OF LITHIUM COMPLEX COMPOUND PARTICLES, METHOD FOR PRODUCING THE SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY CELL |
摘要 |
The present invention relates to lithium composite compound particles having a composition represented by the formula: Li 1+x Ni 1-y-z Co y M z O 2 (M = B or Al), wherein the lithium composite compound particles have an ionic strength ratio A (LiO - /NiO 2 - ) of not more than 0.3 and an ionic strength ratio B (Li 3 CO 3 + /Ni + ) of not more than 20 as measured on a surface of the respective lithium composite compound particles using a time-of-flight secondary ion mass spectrometer. The lithium composite compound particles of the present invention can be used as a positive electrode active substance of a secondary battery which has good cycle characteristics and an excellent high-temperature storage property. |
