Abstract
【解決手段】粒子の大きさが1〜5μmである一つ以上の一次粒子が集まった粒子の大きさが10〜30μmである二次粒子を形成する下記の化学式1乃至4の化合物からなる群より選択される正極活物質であって、前記正極活物質は表面に金属酸化物がコーティングされたリチウム二次電池用正極活物質である。
化学式1:LiCoA2、化学式2:LiCoO2-xBx、化学式3:LiCo1-xMxA2、化学式4:LiCo1-xMxO2-yBy(AはO、S、F又はP、BはS、F又はP、MはAl、Mg、Cr、Mn、Sr、La又はCe、0<x<1、0<y<1)
【選択図】なし
Description
LiCoO2-xBx 化学式2
LiCo1-xMxA2 化学式3
LiCo1-xMxO2-yBy 化学式4
(前記化学式1乃至4において、AはO、S、F及びPからなる群より選択され、BはS、F及びPからなる群より選択され、MはAl、Mg、Cr及びMnからなる群より選択される金属;Sr;La及びCeからなる群より選択されるランタノイド金属であり、0<x<1であり、0<y<1である。)
また、本発明は前記正極活物質の製造方法であって、粒子の大きさが1〜5μmである一つ以上の一次粒子が集まって粒子の大きさが10〜30μmである二次粒子を形成する前記化学式1乃至4の化合物の中で選択される化合物の粉末を製造し;前記粉末を金属アルコキシド溶液または金属水溶液でコーティングし;前記金属アルコキシド溶液または金属水溶液でコーティングされた粉末を熱処理する工程を含むリチウム二次電池用正極活物質の製造方法を提供する。
LiCoO2-xBx 化学式2
LiCo1-xMxA2 化学式3
LiCo1-xMxO2-yBy 化学式4
前記化学式1乃至4の化合物を合成するために、コバルト水酸化物、コバルト硝酸塩またはコバルト炭酸塩などのコバルト塩とリチウム硝酸塩、リチウム酢酸塩、リチウム水酸化物などのリチウム塩を所望の当量比で混合する。また、LiFまたはNaSをさらに添加することもできる。
前記金属アルコキシド溶液はアルコールと前記アルコールに対して1〜10重量%に該当する量の金属を混合した後、これを還流して製造する。前記金属としてはMg、Al、Co、K、Na、Ca、Si、Ti及びVなどを用いることができ、Mgを用いるのが好ましい。前記アルコールとしてはメタノールまたはエタノールを用いることができる。
LiOH 1モルとCo(OH)2 1モルを蒸留水に溶解した。この混合物が十分に反応できる程度に十分な量のエタノールを添加した後、エタノールが殆ど無くなるまでモルタールグラインダー混合を実施した。前記混合物は乾燥空気をブロウイングする条件で400℃で5時間ほど一次熱処理した後、再混合して均一に分散した後、再び750℃で12時間ほど二次熱処理を実施した。この時、温度は3℃/分の速度で昇温し、各温度で一定時間維持した後、自然冷却した。
実施例1において、Mg−メトキシドがコーティングされたLiCoO2粉末を600℃で熱処理する代わりに700℃で熱処理を実施したことを除いては実施例1と同様に実施した。
表面が滑らかで粒子の大きさが10μmである単一粒子からなるLiCoO2粉末(商品名:NC−10、製造社:Nippon Chemical)をMg−メトキシド溶液に浸漬したものを使用したことを除いては実施例1と同様に実施した。
比較例1において、Mg−メトキシドがコーティングされたLiCoO2粉末を600℃で熱処理する代わりに700℃で熱処理を実施したことを除いては比較例1と同一に実施した。
これに反し、(B600)が(B)に比べて酸素分解の温度も上昇して発熱量も比較的に小さくなることから、粒子の大きさが1μmである一次粒子が多数個集まって粒子の大きさが約10μmである二次粒子を形成した状態のLiCoO2粉末を金属アルコキシド溶液で処理する場合、熱的安定性が向上することが分かる。前記結果は図1及び図2のSEM写真に示されたように、実施例1及び比較例1において用いられたLiCoO2粉末の形状の差異に起因すると思われる。
LiOH、Co(OH)2及びLiFを混合して結晶性LiCoF2粉末を製造したことを除いては前記実施例1と同様に実施した。
LiOH、Co(OH)2及びLiFを混合して結晶性LiCoS2粉末を製造したことを除いては前記実施例1と同様に実施した。
