Determination of Coprecipitation pH for Preparing the Nickel-Manganese-Cobalt Mixed hydroxides |
| 초록 |
Lithium nickel-manganese-cobalt oxides (LiNixMnyCo1-x-yO2) have been extensively studied as a promising cathode material for high-energy density lithium-ion battery systems. Lithium nickel-manganese-cobalt oxides synthesized by solid-state method often result in an inhomogeneous elemental distribution or the presence of impurity phase, leading to inferior electrochemical cycling performance. To obtain an ideal cathode material with high-capacity and high-performance, the use of a homogeneous precursor of mixed-hydroxides ((NixMnyCo1-x-y)(OH)2) is widely adopted. Coprecipitation processes often use ammonia water producing a plenty of nitrogen compounds that are characteristic of pungent smell and environmentally unfriendly. In this presentation, we report a novel non-ammonia coprecipitation method using a chelating agent and the method for calculration and determination of optimum pH condition for the preparation of homogeneous mixed-hydroxides. |
