Description
1)分離膜の構造
本発明による分離膜は、多孔性高分子基材、及び前記多孔性高分子基材の少なくとも一面に形成された無機コーティング層を含む。前記無機コーティング層は、無機物粒子及びバインダー樹脂を含み、前記バインダー樹脂は、PVdF系高分子を含む第1バインダー樹脂及び酸価1以下のアクリル系高分子を含む第2バインダー樹脂を含む。また、本発明の一実施形態において、前記無機コーティング層は、表層部におけるバインダー樹脂の含量が高くて分離膜と電極との接着力に優れる。
前記多孔性高分子基材は、負極と正極との電気的接触を遮断しながら、イオンを通過させるイオン伝導性バリア(porous ion-conducting barrier)であって、内部に複数の気孔が形成された基材を意味する。複数の気孔が相互連結された構造になっており、基材の一面から他面へと気体または液体が通過可能である。
a)高分子樹脂を溶融/押出して成膜した多孔性フィルム
b)a)の多孔性フィルムが2層以上積層された多層膜
c)高分子樹脂を溶融/紡糸して得られたフィラメントを集積して製造された不織布ウェブ
d)b)の不織布ウェブが2層以上積層された多層膜
e)a)~d)のうち二つ以上を含む多層構造の多孔性複合膜
本発明において、前記分離膜は、前記多孔性高分子基材の少なくとも一面に形成された無機コーティング層を含む。前記無機コーティング層は、バインダー樹脂及び無機物粒子を含む混合物を含む。本発明の一実施形態において、前記無機コーティング層は、層の内部に無機物粒子が密集した状態で充填され得、無機物粒子同士の間に形成されたインタースティシャルボリュームによる多数の微細気孔を有し得る。これら微細気孔が互いに連結された構造になって、一面から他面へと気体または液体が通過可能な多孔性構造を有し得る。本発明の一実施形態において、前記無機物粒子はバインダー樹脂によって表面の全部または少なくとも一部がコーティングされ、前記バインダー樹脂を介して粒子同士が面結着及び/または点結着され得る。本発明の一実施形態において、前記無機物粒子は、バインダー樹脂と無機物粒子との総量100重量%に対して50重量%以上の比率で無機コーティング層に含まれ得、望ましくは無機物粒子は60重量%以上、70重量%または80重量%以上で含まれ得る。また、上記の範囲内で95重量%以下または90重量%以下で含まれ得る。
B1.バインダー樹脂
本発明の一実施形態において、前記無機コーティング層は、第1バインダー樹脂であるPVdF系高分子及び第2バインダー樹脂であるアクリル系高分子を含み、ここで前記アクリル系高分子は酸価が1以下のものである。
(数1)
酸価=A×N×f×KOH消費量(mL)/S
本発明の具体的な一実施形態において、前記無機物粒子は、電気化学的に安定さえすれば特に制限されない。すなわち、本発明で使用可能な無機物粒子は、適用される電気化学素子の作動電圧範囲(例えば、Li/Li+基準で0~5V)で酸化及び/または還元反応が起きないものであれば特に制限されない。特に、無機物粒子として誘電率の高い無機物粒子を使用する場合、液体電解質内の電解質塩、例えばリチウム塩の解離度増加に寄与して電解液のイオン伝導度を向上させることができる。
まず、バインダー樹脂を溶媒に溶解して高分子バインダー溶液を用意する。その後、無機物粒子及び溶媒を含む混合物に前記高分子バインダー溶液を投入し混合して無機コーティング層形成用スラリーを用意する。前記混合物及び/またはスラリーには、必要に応じて分散剤のような補助剤をさらに投入してもよい。次いで、これを多孔性高分子基材上に塗布し、加湿条件下で所定時間静置してバインダー樹脂を固化(乾燥)させる。加湿条件で固化しながら前記スラリー中のバインダー樹脂の相分離が誘発される。本発明の一実施形態において、前記加湿条件は相対湿度約40%~80%の条件であり得る。このような相分離の過程で、溶媒が無機コーティング層の表面部に移動し、溶媒の移動とともにバインダー樹脂が無機コーティング層の表面部に移動されながら、表層部にバインダー樹脂の含量の高い電極接着部が形成される。本発明の一実施形態において、加湿相分離を通じてPVdF系高分子とともにアクリル系高分子も一緒に表層部に移動する。これによって、電極接着部内のPVdF系高分子とアクリル系高分子との含量比は最初スラリー製造時に投入された含量比と類似した水準を維持し、これらの含量比は無機コーティング層の全体厚さにおいて均一に維持される。このように本発明は、PVdF系高分子によって表層部にバインダーの含量の高い電極接着部が効果的に形成され、前記電極接着部にアクリル系高分子が適正量含まれることで電極と分離膜との間の高い接着力が発揮される。
一方、本発明は、上述した分離膜を含む二次電池を提供する。前記電池は、負極、正極及び前記負極と正極との間に介在された分離膜を含み、前記分離膜は、上述した特徴を備えた低抵抗分離膜である。

それぞれの実施例または比較例(例えば、実施例1)で収得した分離膜サンプルを70mm(長さ)×15mm(幅)の大きさで切断して両面テープを張り付けたガラス板上に接着した試片を用意した。それぞれの試片を接着強度測定機(LLOYDインストルメント製、LF plus)に固定し、上側の分離膜試験片を25℃で25mm/分の速度で180゜の角度で剥離し、このときの強度を測定した。
天然黒鉛、SBR(スチレンブタジエンゴム)、CMC及び導電材(重量比で90:2.5:2.5:5)を水に投入して負極スラリーを収得した。前記負極スラリーを銅薄膜(厚さ20μm)上に5mg/cm2のローディング量で塗布して乾燥した。次いで、これを90℃、8.5MPaの条件で圧延し、60mm(長さ)×25mm(幅)に切断して負極を収得した。それぞれの実施例及び比較例で収得した分離膜を70mm(長さ)×25mm(幅)に切断し、用意した負極と分離膜をプレスを用いて70℃、4MPaの条件でラミネートして試片を製作した。用意した試片を両面テープを用いてガラス板に張り付けて固定し、このとき、負極がガラス板に対面するように配置した。試片の分離膜部分を25℃で25mm/minの速度で180゜の角度で剥離し、このときの強度を測定した。
一方、アクリル系高分子であるPMMAの含量比に応じた加湿相分離の効果を確認するため、下記のように参照例1a~参照例1dを行った。
アセトン200gにバインダー樹脂を溶解させて高分子溶液を製造した。多孔性高分子基材(東レ製、B12PA1)を用意し、ディップコーティング法で前記高分子溶液を前記多孔性高分子基材の表面にコーティングして、相対湿度(RH)約50%の条件で2分間静置してバインダー樹脂の加湿相分離を誘導した。それぞれの参照例で使用されたバインダー樹脂などの成分と含量比は下記表6のようである。
