Description
(正極材料の作製)
本実施例では、原料として二酸化マンガン、酸化コバルト、酸化ニッケル及び炭酸リチウムを使用し、所定の元素比となるように秤量した後、エタノールを加え、遊星ボールミルにより湿式で5時間粉砕、混合した。次に、この粉末に1000℃で10〜30時間の焼成を行った後、粉末を解砕して層状正極材料(1)を得た。
次に、正極材料(1)の特性を評価するための正極板を以下の手順で作製した。あらかじめ結着剤を溶媒のN-メチル-2-ピロリジノン(以下、NMPと略す)に溶解した溶液と層状正極材料及び炭素系導電材を均一に混合して正極合材スラリーを作製した。このとき、正極材料、炭素系導電材及び結着剤を重量百分率比で表してそれぞれ、85:10.7:4.3の割合となるように混合した。このスラリーを、厚み20μmのアルミ集電体箔上に均一に塗布した後、100℃で乾燥し、プレスにて1.5ton/cm2で加圧し、約40μm厚の塗膜を形成した。
次に、円筒型電池を作製して正極材料のサイクル寿命特性及び安全性を評価するため、正極材料(1)〜(3)を用いた正極板を塗布幅5.4cm、塗布長さ50cmとなるよう切断し、電流を取り出すためにアルミニウム箔製のリード片を溶接し正極板を作製した。
作製した電池の充放電サイクル特性の評価は,充電終止電圧4.2V,放電終止電圧3.0Vとし、0.5Cの放電レートで行った。各電池で200サイクルの寿命試験を行った結果を表2に示す。遷移金属に占めるNi組成が44%以下のときは、200サイクルでの容量維持率が85%以上であったが、後述するNi組成が0.45以上の比較正極材料を用いたときの容量維持率は54%であり、サイクル寿命の劣化が認められた。
次に、実施例1の正極材料(1)〜(3)を用いて作製した電池(1)〜(3)の各リチウム二次電池の安全性を検討するため、内部短絡試験(釘さし試験)を行った。この試験の充電条件は、充電電流200mAで充電終止電圧4.25Vまで定電流充電した後、4.25Vの定電圧で8時間充電する定電流定電圧充電とした。電池(1)〜(3)に対して10本の電池を充電した後、直径5mmの釘を各電池の側面から貫通速度10cm/分で貫通させ、開裂弁の作動、発火、破裂などの異常の有無を観察した。以上の手順により各電池10本の異常発生確率を調べた。
本比較例では、実施例1と同様の手順で作製した表1に示す組成の比較正極材料(1)、(2)について、実施例1と同様の手順でX線回折及びBET比表面積測定を行なった。
本実施例では、実施例1と同様の手順で作製した表1に示す組成(Al,B,Fe,Cu,Mg,Zn,GaあるいはSiで遷移金属を置換)の正極材料(4)〜(11)を、実施例1と同様の手順でX線回折及びBET比表面積測定を行なった。なお、置換を行う元素の原料には酸化物を用い、他の酸化物原料とともに遊星ボールミルで混合した。
本比較例では、実施例1と同様の手順で化学式がLi1.02Mn0.40Ni0.55Co0.05O2となるように比較正極材料(3)を作製し、実施例1と同様の手順でX線回折及びBET比表面積測定を行なった。X線回折で、(012)面の回折ピーク強度I012と(006)面の回折ピーク強度I006との合計強度の、(101)面の回折ピーク強度I101に対する強度比R2を算出したところ、R2は0.45であった。さらに、この比較正極材料(3)を用いて実施例1と同様に試験電池を作製し、-30℃で電池の内部抵抗を測定したが、抵抗は230Ω以上であった。
実施例1の正極材料(1)を用い、正極板の空隙率を9%から36%となるように電極密度を調整した。この正極板を用いた試験電池を作製し、-30℃における電池内部抵抗を測定した。空隙率が9%及び36%の正極板を用いたときの内部抵抗は,空隙率が12〜24%の正極板と比較して、それぞれ1.2倍及び1.4倍となった。
実施例1の正極材料(1)を用いた電池(1)の容量を測定した。充電条件は充電電流200mAで充電終止電圧4.2Vまで定電流充電後4.2Vの定電圧で計8時間の充電を行う定電流定電圧充電とした。放電は放電電流200mAで放電終止電圧2.5Vの定電流放電とした。次に、この電池容量の充電状態を50%とし、開回路電圧が3.5V〜4.0Vのときに-30℃での電池内部抵抗を測定した。開回路電圧が3.6〜3.9Vのときに電池内部抵抗を低下させることができた。一方、正極板の正極活物質量及び負極板の負極活物質を調整して電池の充電状態を90%としたときは、開回路電圧が3.8〜4.1Vのときに電池内部抵抗が低下した。
