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１］
ニッケル系リチウム−ニッケル複合酸化物粒子として遷移金属組成がＬｉ１．０３Ｎｉ０．８２Ｃｏ０．１５Ａｌ０．０３で表される複合酸化物粒子１５ｇを２０ｍｌの水と１−プロパンチオール酸０．０２３３ｇ（１．６２×１０ −５ ｍｏｌ／ｍ２ｓ相当）を常温で混合した。この混合は、周速１０．５ｍ／ｓ、撹拌時間１分でホモジナイザーを用いて行われた。混合後、吸引濾過により水を分離し、減圧下１００℃で２時間乾燥させことで被覆リチウム−ニッケル複合酸化物粒子を作成し、下記の評価を行った。
[Example 1]
As nickel-based lithium-nickel composite oxide particles, 15 g of composite oxide particles whose transition metal composition is represented by Li 1.03 Ni 0.82 Co 0.15 Al 0.03 are mixed with 20 ml of water and 1-propanethiolic acid 0. 0.0233 g (equivalent to 1.62 × 10 −5 mol / m 2 s) was mixed at room temperature. This mixing was performed using a homogenizer at a peripheral speed of 10.5 m / s and a stirring time of 1 minute. After mixing, water was separated by suction filtration and dried at 100 ° C. under reduced pressure for 2 hours to prepare coated lithium-nickel composite oxide particles, and the following evaluation was performed.
