Description
[正極の製造]
正極活物質としてLi(Li1.2Co0.1Ni0.1Mn0.6)O2を使用し、導電材(carbon black)、バインダー(PVdF)をそれぞれ95:2:3の重量比でNMP(N−methyl−2−pyrrolidone)に入れてミキシングして、正極合剤を製造した。
負極としては天然黒鉛/Si系活物質を使用し、導電材(carbon black)、バインダー(SBR)、増粘剤(CMC)をそれぞれ94:2:3:1の重量比でH2Oに入れてミキシングして、負極合剤を製造した。
前記電流集電体を製造する過程において、プラズマ処理方法を用いて集電体の表面処理を行った。プラズマ処理は、12kwのMFを加えると、電場によって電子が加速されて、GN2(N2)ガスとCDA(Clean Dry Air)ガスをイオン化させて発生した活性種が250mm*250mmのアルミニウムホイルまたは銅ホイルと衝突するようにして、集電体の表面処理を行った。
前記負極と正極との間に分離膜(セルガード(商標)、厚さ:20μm)を介在して電極組立体を製造した後、前記電極組立体をパウチ型電池ケースに収納し、エチルカーボネートとジメチルカーボネートとエチルメチルカーボネートが体積比を基準として1:1:1で混合されており、リチウム塩として1MのLiPF6を含んでいるリチウム非水系電解液を添加して、リチウム二次電池を製造した。
正極集電体として、別途の表面処理を施していないアルミニウムホイルを使用し、負極集電体として、別途の表面処理を施していない銅ホイルを使用して製造したこと以外は、実施例1と同様の方法でリチウム二次電池を製造した。
実施例1のアルミニウムホイルと銅ホイル集電体の表面状態がプラズマ表面処理を通じて親水性に変化したかを確認するために、接触角を測定した。実施例1の正極、負極集電体を切り取ってスライドガラスに固定させた後、H2Oを3μL滴下して接触角を測定し、下記の表1に示す。
実施例1及び比較例1の電極を用いて接着力試験を行った。実施例1及び比較例1の電極を切り取ってスライドガラスに固定させた後、電極集電体を剥離しながら180度剥離強度を測定した。評価は、5個以上の剥離強度を測定して平均値として定めて、下記の表2に示す。
実施例1及び比較例1の電池を用いて、25℃の温度で、0.1Cの充電電流で充電終止電圧4.25Vまで充電した後、放電速度を0.1C、0.2C、0.5C、1C、0.1Cに変化させながら、それぞれ2サイクル(最後の0.1Cだけ1サイクル)ずつ放電終止電圧2.5Vまで放電する充放電試験を行った。下記の図1及び表3は、0.1C放電容量に対する0.2C、0.5C、1C放電容量を示す。下記の図2は、実施例1及び比較例1の電池を用いて、45℃の温度で、0.2Cの充電電流で充電終止電圧4.25Vまで充電した後、0.5Cの放電電流で放電終止電圧2.5Vまで放電する充放電サイクル試験を行った結果を示す。
