Active material of positive electrode for non-aqueous electrode secondary battery and method for preparing the same and non-aqueous electrode secondary battery using the same |
| abstract |
An active material of a positive electrode for a non-aqueous electrode secondary battery employing lithium cobaltate represented by the formula LiCoO2, which comprises a mixture of primary particles of small crystals having a Feret's diameter in a projection drawing by SEM observation in a range from 0.4 to 10 .mu.m and an average diameter of 5 .mu.m or less, and secondary particles formed by coagulation of the primary particles and having a diameter of 4 to 30 .mu.m, wherein the mole ratio of Co to Li is 0.97 to 1.03, at least a part of small crystals constituting the secondary particles are jointed by the junction through sintering, and the secondary particles are in the shape of a circle or an ellipse. And also are provided an active material of a positive electrode for a non-aqueous electrode secondary battery, wherein secondary particles account for 90% or more of the particles having a Feret's diameter of 9 .mu.m or more and particles having a Feret's diameter of 6 .mu.m or more constitute 70% or more by volume of the total mixture, which allows the improvement of discharge capacity, capability of keeping the level of discharge capacity, and high efficiency discharge capacity and a method for the production thereof, and a non-aqueous electrode secondary battery manufactured using the active material of a positive electrode. |
