Description
本出願は、2018年1月12日付韓国特許出願第10-2018-0004212号に基づいた優先権の利益を主張し、当該韓国特許出願の文献に開示された全ての内容は本明細書の一部として含まれる。
本発明は、パウチフィルム及びその製造方法に関し、より詳細には、パウチの柔軟性、防水性及び耐電解液性のいずれも優れたパウチフィルム及びその製造方法に関する。
一般的にリチウム二次電池1を製造するために、先ず電極活物質とバインダー及び可塑剤を混合したスラリーを正極集電体及び負極集電体に塗布して、正極と負極を製造し、これを分離膜(Separator)の両側に積層することで電極組立体10を形成する。そして、電池ケース13に電極組立体10を収納し電解液を注入してからシーリングする。
ポリエチレンテレフタレート(PET)で製造された表面保護層の片面に接着剤を塗布し、直径が0.1μmから10μmであるアルミニウム(Al)金属粒子を、プラズマ・アトマイズ法(Plasma Atomization Method)を用いて蒸着した。その後、温度150℃及び圧力200MPaを維持し、加圧焼結法を用いて前記金属粒子を焼結することでガスバリア層を形成した。このとき、形成されたガスバリア層の厚さは10μmであった。次いで、ガスバリア層の片面に接着剤を塗布し、ポリプロピレン(PP)で製造されたシーラント層を積層し、パウチフィルムを製造した。
ポリエチレンテレフタレート(PET)で製造された表面保護層の片面に接着剤を塗布して、厚さ15μmのアルミニウム薄膜(Al Foil)を表面保護層の片面の接着剤上に積層し、前記アルミニウム薄膜上に接着剤を塗布した後、ポリプロピレン(PP)で製造されたシーラント層を積層し、図3に示された構造を有するパウチフィルムを製造した。
金属粒子を蒸着した後、焼結工程を行っていない点を除いては、実施例1と同一の方法でパウチフィルムを製造した。前記のように製造されたパウチフィルムは、図13に示された構造を有する。
1.柔軟性(Flexibility)
次のように曲げテスト(Bending Test)を行って柔軟性(Flexibility)を測定した。先ず、製造例1、比較製造例1、及び比較製造例2で製造されたパウチフィルムをそれぞれ15mm×150mmの大きさに裁断した後、前記パウチフィルムの一側を全て耐折度試験機(MIT folding endurance tester)の上部治具に固定させ、他側を下部固定治具(チップの曲率R0.1mm、荷重250g)に固定させる。そして、パウチフィルムを±90゜の角度、175cpmの速度で同一に曲げを繰り返した。このような曲げを繰り返した後、それぞれのパウチフィルムにLED光を照射し、ピンホール(Pinhole)が発生する直前の曲げ回数を測定した。
製造例1、比較製造例1、及び比較製造例2で製造されたパウチフィルムをそれぞれ25mm×100mmの同一の大きさに裁断し、125mlのナルゲンボトル(Nalgene Bottle)に電解液80ml(リチウム塩LiPF6 1M、そしてエチレンカーボネート(EC):エチルメチルカーボネート(EMC):ジメチルカーボネート(DMC)をそれぞれ3:3:4の比率で溶かして製造)と前記パウチフィルムを収納し、パラフィンで入口を密封した。前記ナルゲンボトルをアルミニウム包装紙でシーリングし、85℃で24時間保管した後、前記パウチフィルムを取り出し水で濯いでから水分を完全に除去した。そして、前記パウチフィルムの幅を両側から5mmずつ切断し、15mm×100mmの大きさのサンプルを製造した。その後、前記サンプルの表面保護層に切れ目を入れベンディングを繰り返してガスバリア層まで切断し、前記サンプルを両方に引っ張りシーラント層の一部が露出されるように剥がす。前記剥がしたシーラント層を万能材料試験機(UTM:Universal Testing Machine)の上部治具に固定させ、残りの部分は、両面テープを用いてスライドガラスに付着した後、下部治具に固定させる。以後、剥離速度50mm/min、グリップギャップ(grip gap)80mm、試験距離(test distance)30mmの条件でシーラント層とガスバリア層の剥離に要求される力を測定し、この力を接着強度として評価した。
製造例1、比較製造例1、及び比較製造例2で製造されたパウチフィルムのそれぞれを、108mm×108mmの大きさに裁断した後、透湿度試験装置の内部にそれぞれ取り付けた。その後、パウチフィルムの一面には水蒸気が含まれていない乾燥した窒素ガスを、他面には水蒸気を流入させた。このとき、パウチフィルムの両面に流入されるガスが混合しないよう、前記ガスがそれぞれ流入される二つの空間を互いに隔離させた。一方、実験を行う間の温度は38℃、前記湿度は100%RHに設定し維持した。そして、24時間の間、湿度センサーを用いて乾燥した窒素ガスを流入した前記一面での水蒸気の量を測定した。このような水蒸気の量を前記一面の面積で割算することで、24時間の間にパウチフィルムを透過した単位面積当たりの水蒸気の量を導出し、これをWVTRとして評価した。
21 ガスバリア層
22 表面保護層
23 シーラント層
210 金属粒子
