Description
なお、ρ´は、理論密度を示し、例えば、測定対象の材料から、内部に空隙が全く存在しないフィルムを成形した際における密度とすることができる。
このようなリチウム金属二次電池1では、セパレータ4が、イオン伝導性の無機酸化物を含有する多孔質体である。そのため、充放電を繰り返しても、負極2において、デンドライトの発生が抑制される。この機構は、下記のように推察される。
(正極の作製)
正極活物質としてLiCoO2(平均粒子径(D50)5μm)90質量部、導電剤としてカーボン粉末5質量部、バインダーとしてポリフッ化ビニリデン5質量部、溶媒としてN−メチルピロリドン(NMP)400質量を混合して、正極組成物スラリーを調製した。
エアロゾルデポジション法を用いて、正極の正極活物質層に、セパレータを直接形成した。
硝酸リチウム粒子(LiNO3、平均粒子径(D50)500nm)をSEAのセパレータ表面にスプレーガンを用いて、硝酸リチウムを付着させた。
銅箔(負極集電体、厚さ30μm)に、リチウム金属箔(負極活物質層、厚さ25μm)を押圧することにより、負極を作製した。
エチレンカーボネート(EC)とジメチルカーボネート(DMC)とを50:50(体積比)で混合した混合溶液に、2.0mol/LとなるようにLiPF6を溶解させて、電解質含有有機溶媒を調製した。
・実施例1
SEAおよび負極を、セパレータがリチウム金属箔に接触するように積層させることにより、電池セルを得た。
酸化剤の付着を実施しなかった以外は、実施例1と同様にして、実施例2のリチウム金属二次電池を製造した。
実施例1と同様の正極および負極を用い、これら2つの電極間に不織布セパレータ(厚み30μm)を挟んで、電池セルを作製した。電池セルをアルミニウムのラミネートフィルムで封止した。完全に封止する前に、不織布セパレータおよび正極活物質層が完全に湿潤するように電解液を十分に加えて、ラミネートフィルム内部を電解液で満たした。
上記(セパレータの作製)と同様の方法にて、アルミニウム箔(厚さ20μm)の表面に、実施例1と同様の厚み5μmのセパレータ(イオン伝導性無機酸化物からなる多孔質体)を形成して、柔軟性試験用の試料を作製した。
実施例1〜2および比較例1の電池を、4.2〜2.7Vの間で定電流を用いて繰り返し充放電させる充放電サイクルに供した。1.5mA/cm2の電流で、充放電サイクルを200回実施した。
比較例1の電池では、負極と不織布セパレータとの界面に、デンドライトが形成されていたため、さらに充放電を繰り返すと、デンドライトが成長し、最終的に不織布セパレータを貫通して正極に達する危険があることが分かる。
実施例1〜2の電池のそれぞれに電流源Aを並列に接続し、釘刺し試験の終了まで高電流を確保とした。電流源Aとしては、定格電圧3.9Vで7Aの高電流を2分間以上供給可能である大型リチウムイオン電池パック(市販品)を用いた。
