Description
〔リチウム遷移金属複合酸化物の作製〕
Li2CO3と、(Ni0.4Co0.3Mn0.3)3O4と、ZrO2と、MgOとをモル比で、Li:(Ni0.4Co0.3Mn0.3):Zr:Mg=1.00:0.99:0.005:0.005となるように混合し、この混合物を空気雰囲気中950℃で20時間焼成することにより、LiNi0.396Co0.297Mn0.297Zr0.005Mg0.005O2を得た。
上記のように作製したリチウム遷移金属複合酸化物と、導電剤としての炭素材料と、結着剤としてのポリフッ化ビニリデンを溶解したN−メチル−2−ピロリドン溶液を、活物質と導電剤と結着剤の重量比が90:5:5となるように混合して正極スラリーを作製した。作製したスラリーを集電体としてのアルミニウム箔上に塗布した後、乾燥し、その後圧延ローラーを用いて圧延し、集電体タブを取り付けることにより正極を作製した。
負極活物質としての黒鉛と、結着剤としてのSBRと、増粘剤としてのカルボキシメチルセルロースを溶かした水溶液を、活物質と結着剤と増粘剤の重量比が98:1:1になるように混練して負極スラリーを作製した。作製したスラリーを集電体としての銅箔上に塗布した後、乾燥し、その後圧延ローラーを用いて圧延し、集電タブを取り付けて負極を作製した。
エチレンカーボネート(EC)と、ジエチルカーボネート(DEC)とを体積比3:7で混合した溶媒に、溶質としてのLiPF6を1モル/リットルとなるように溶解し、電解液を作製した。
上記で作製した正極を作用極として用い、対極及び参照極としてリチウム金属を用い、図1に示す三電極式ビーカーセルA1を作製した。図1に示すように、ビーカーセルの容器中には電解液4が入れられており、この電解液4に、作用極1、対極2、及び参照極3が浸漬されている。また、電解液4としては、上記で作製した電解液を用いている。
上記の正極の作製において、正極活物質として、上記リチウム遷移金属複合酸化物と、スピネル構造を有するリチウムマンガン複合酸化物(Li1.1Al0.1Mn1.8O4)とを重量比(リチウム遷移金属複合酸化物:リチウムマンガン複合酸化物)で7:3となるように混合して、この混合物を正極活物質として用いる以外は、上記と同様にして正極を作製した。
実施例1のリチウム遷移金属複合酸化物の作製において、ZrO2とMgOとを添加せずに、リチウムと、遷移金属の合計とのモル比を等モルになるように混合する以外は、実施例1と同様にしてリチウム遷移金属複合酸化物を作製し、これを用いて三電極式ビーカーセルB1及び非水電解質二次電池B2を上記と同様にして作製した。
実施例1のリチウム遷移金属複合酸化物の作製において、ZrO2を含有させずに、MgOのみを、これと遷移金属との合計に対して0.5モル%となるように混合する以外は、同様にしてリチウム遷移金属複合酸化物を作製し、これを用いて三電極式ビーカーセルC1を作製した。
実施例1のリチウム遷移金属複合酸化物の作製において、MgOを含有させずに、ZrO2のみを、これと遷移金属との合計に対し0.5モル%となるように混合し、リチウム遷移金属複合酸化物を作製し、これを用いて三電極式ビーカーセルD1及び非水電解質二次電池D2を作製した。
三電極式ビーカーセルA1、B1、C1及びD1について、放電容量を測定した。放電容量の測定は、9.3mAと3.1mAの2段階充電で4.3Vまで充電した後、放電終止電圧を3.1Vに設定し、9.3mAで3.1Vまで放電したときの容量を測定し、これを放電容量とした。測定結果を表1に示す。
電池A2、B2及びD2について、定格容量を測定した。電池の定格容量は、1400mAの定電流−定電圧(70mAカット)で4.2Vまで充電した後、放電終止電圧を3.0Vに設定し、470mAで3.0Vまで放電したときの電池容量を定格容量とした。
電池A2、B2及びD2について、IV抵抗を測定した。1400mAでSOC50%まで充電した後、SOC50%を中心として280mA、700mA、2100mA、及び4200mAで10秒間充電と放電をそれぞれ行い、それぞれの場合における10秒後の電池電圧を電流値に対してプロットし、その傾きを放電時のIV抵抗とした。
電池A2、B2及びD2について、1400mAでSOC50%まで充電した後、温度を65℃に保持した恒温槽内で30日間保存試験を行った。保存後、上記と同様にして定格容量を測定した後、上記と同様にして放電時のIV抵抗測定を行った。この結果から、保存試験前後のIV抵抗の増加を算出した。電池A2、B2及びD2についての保存前後のIV抵抗の増加率を表2に示す。
