Description
まず、本発明のリチウムイオン二次電池の実施形態について詳細に説明する。
二次電池要素61,62,63,64は、図2に示すように、それぞれ、互いに対向する板状のカソード(正極活物質層)10及び板状のアノード(負極活物質層)20と、カソード10とアノード20との間に隣接して配置される板状の電気絶縁性のセパレータ40と、電解質を含みカソード10、アノード20、及び、セパレータ40中に含有された電解質溶液(図示せず)と、から各々構成されている。
アノード20は、負極活物質、導電助剤、結着剤等を含む層である。以下アノード20について説明する。
れる。
カソード10は、正極活物質、導電助剤、結着剤等を含む層である。以下カソード10について説明する。
アノード20とカソード10との間に配置されるセパレータ40は、電気絶縁性の多孔体から形成されていれば特に限定されず、公知の二次電池要素に用いられているセパレータを使用することができる。例えば、電気絶縁性の多孔体としては、ポリエチレン、ポリプロピレン又はポリオレフィンからなるフィルムの積層体や上記樹脂の混合物の延伸膜、或いは、セルロース、ポリエステル及びポリプロピレンからなる群より選択される少なくとも1種の構成材料からなる繊維不織布が挙げられる。
電解質溶液は、アノード20及びカソード10、及びセパレータ40の孔の内部に含有されている。電解質溶液は、特に限定されず、公知のリチウムイオン二次電池要素に用いられている、リチウム塩を含む電解質溶液(電解質水溶液、有機溶媒を使用する電解質溶液)を使用することができる。ただし、電解質水溶液は電気化学的に分解電圧が低いことにより、充電時の耐用電圧が低く制限されるので、有機溶媒を使用する電解質溶液(非水電解質溶液)であることが好ましい。二次電池要素の電解質溶液としては、リチウム塩を非水溶媒(有機溶媒)に溶解したものが好適に使用される。リチウム塩としては、例えば、LiPF6、LiClO4、LiBF4、LiAsF6、LiCF3SO3、LiCF3、CF2SO3、LiC(CF3SO2)3、LiN(CF3SO2)2、LiN(CF3CF2SO2)2、LiN(CF3SO2)(C4F9SO2)、LiN(CF3CF2CO)2等の塩が使用される。なお、これらの塩は1種を単独で使用してもよく、2種以上を併用してもよい。
リード線12及びリード線22は、図1に示すように、リボン状の外形を呈してケース50内からシール部50bを通って外部に突出している。
ケース50は、積層構造体85を密封し、ケース内部へ空気や水分が進入するのを防止できるものであれば特に限定されず、公知の二次電池要素に用いられているケースを使用することができる。例えば、エポキシ樹脂等の合成樹脂や、アルミニウム等の金属シートを樹脂ラミネートしたものを使用することができる。ケース50は図1に示すように、矩形状の可撓性のシート51Cを長手方向の略中央部で2つ折りにして形成した
ものであり、積層構造体85を積層方向(上下方向)の両側から挟み込んでいる。2つ折りにされたシート51Cの端部のうち、折り返し部分50aを除く3辺のシール部50b
がヒートシール又は接着剤により接着されており、積層構造体85が内部に密封されている。また、ケース50は、シール部50bにおいて絶縁体14と接着することによりリード線12,22をシールしている。
次に、上述したリチウムイオン二次電池100の作製方法の一例について説明する。
2辺のシール部50b、50bのみを、例えばシール機等を用いて所定の加熱条件で所望のシール幅だけヒートシールする。これによって、積層構造体85を導入するための開口部50cが形成された袋状のケース50fが得られる。
まず、カソード積層体を以下の手順により作製した。まず、正極活物質としてLiMn0.33Ni0.33Co0.34O2(下付き数字は原子比)、導電助剤としてアセチレンブラック、結着剤としてポリフッ化ビニリデン(PVdF)を用意し、これらの重量比が正極活物質:導電助剤:結着剤=90:6:4となるようにプラネタリーミキサで混合分散した後、これに溶媒としてのNMPを適量混合して粘度調整し、スラリー状のカソード用塗布液(スラリー)を調整した。
負極活物質担持量を3.3mg/cm2とし、正極活物質担持量を6.0mg/cm2とする以外は、実施例と同様にした。
負極活物質担持量を3.8mg/cm2とし、正極活物質担持量を7.0mg/cm2とする以外は、実施例と同様にした。
負極活物質担持量を2.2mg/cm2とし、正極活物質担持量を4.0mg/cm2とする以外は、実施例と同様にした。
負極活物質担持量を4.1mg/cm2とし、正極活物質担持量を7.5mg/cm2とする以外は、実施例と同様にした。
負極活物質担持量を1.9mg/cm2とし、正極活物質担持量を3.5mg/cm2とする以外は、実施例と同様にした。
負極活物質を、X線回折のピーク強度比P101/P100が2.6である天然黒鉛(日立粉末製GP870)に代える以外は実施例1と同様にした。
負極活物質を、X線回折のピーク強度比P101/P100が2.7である人造黒鉛(SEC製SGB−R)に代える以外は実施例1と同様にした。
負極活物質を、X線回折のピーク強度比P101/P100が1.2である人造黒鉛(大阪ガス製MCMB)に代える以外は実施例1と同様にした。
負極活物質を、X線回折のピーク強度比P101/P100が1.5である人造黒鉛(ペトカ製MCF)に代える以外は実施例1と同様にした。
