Description
LiaNibM1cM2d(O)2で示される化合物(最終生成物)の合成に好適に使用できる。本発明の部分酸化混合金属水酸化物から得られる最終生成物−リチウム混合金属酸化物−は単純な合成ルートによって得られる。
サンプルについても対象試料の滴定と平行して行う必要がある。チオ硫酸ナトリウムの消費量が評価に使用される。そして化合物中の総金属成分の平均酸化度は以下の式により求められる。
NiSO4、CoSO4及びMnSO4を各0.7モル含む溶液を連続的に沈殿反応槽に供給した。
NiSO4、CoSO4及びMnSO4を各0.7モル含む溶液を連続的に沈殿反応槽に供給した。
NiSO4、CoSO4及びMnSO4を各0.7モル含む溶液を連続的に沈殿反応槽に供給した。この金属含有溶液中に2.5モルNaOH溶液および12.5%NH3溶液を同時にかつ連続的に添加した。これらの供給流量は、静置状態において、アンモニア濃度が8g/l、フリーの水酸化ナトリウム濃度が0.5g/lとなるように調節した。このような条件下で溶液のpHは12.0であった。高pHにより、金属含有溶液から金属成分が水酸化物として確実に沈殿する。種々の溶液添加量により、反応槽内の固形分濃度は50g/lとした。反応槽内の温度は外部熱源により50℃に調節した。固形物の平均滞留時間は5時間であった。
