Description
このような問題を解決するために、リチウム−ニッケル複合酸化物粒子表面上にコーティング剤を用いることにより被覆する方法が提案されている。このようなコーティング剤としては、無機系のコーティング剤と有機系のコーティング剤に大別され、無機系のコーティング剤としてはヒュームドシリカ、酸化チタン、酸化アルミニウム、リン酸アルミニウム、リン酸コバルト、フッ化リチウムなどの材料が、有機系のコーティング剤としては、カルボキシメチルセルロース、フッ素含有ポリマーなどの材料が提案されている。 In order to solve such a problem, a method of coating the surface of the lithium-nickel composite oxide particles by using a coating agent has been proposed. Such coating agents are broadly classified into inorganic coating agents and organic coating agents, and inorganic coating agents include fumed silica, titanium oxide, aluminum oxide, aluminum phosphate, cobalt phosphate, and fluoride. of materials such as lithium, as the coating agent of organic, carboxymethyl cellulose, the material such as a fluorine-containing polymer has been proposed.
（実施例３）
実施例２において複合酸化物とリン酸二水素アンモニウムとの混合物を加熱する温度を１２０℃としたほかはすべて実施例２と同じにして、実施例３とした。
(Example 3)
Be the same as any addition to the temperature for heating the mixture of the composite oxide and ammonium dihydrogen phosphate and 120 ° C. Example 2 In Example 2, it was as in Example 3.
