| titleOfInvention | Manufacturing method of positive electrode material for non-aqueous lithium secondary battery using spherical cobalt hydroxide |
| abstract | The present invention relates to a method for producing a positive electrode material for a non-aqueous lithium secondary battery using a spherical cobalt hydroxide, by using a precipitation reaction in the liquid phase to produce a spherical cobalt hydroxide in which dissimilar metal is uniformly substituted for the final positive electrode material It is to suppress the collapse of the structure at high voltage to improve the life characteristics. According to the present invention, cobalt raw materials, hydroxyl raw materials, dissimilar metal raw materials and amine-based raw materials are represented by the formula, Co 1-x M x (OH) 2 (0.00 <x≤0.10, M = Al, Mg, Ti, etc) It is possible to prepare spherical cobalt hydroxide having a particle size of 15 ~ 30㎛ by precipitating to have a composition ratio of. And it is possible to prepare a spherical cobalt oxide having a particle size of 10 to 25㎛ by maintaining the prepared cobalt hydroxide in the temperature range of 500 ~ 800 ℃ 5-20 hours. The cathode material manufactured using such cobalt oxide shows excellent life characteristics even under 4.5V high voltage charge / discharge conditions. |
