Description
直径5cmのアルミ皿に樹脂を約1g秤量し、105℃で1時間乾燥させ、残分を秤量することで算出した。
ブルックフィールド型回転粘度計を用いて、液温23℃、回転数10rpm、No.2またはNo.3ローターにて測定した。
得られたポリマーエマルジョンを23℃、50%RH下で7日間乾燥させた後、60℃、12h真空乾燥し、乾燥皮膜を作成した。乾燥皮膜をプロピレンカーボネート/ジエチルカーボネート(質量比で1:1)電解液溶媒に60℃、12日浸漬させ、耐膨潤率を測定した。
集電体である銅箔に下記で得られた電極用スラリーをWet150μm/m2塗布し、60℃、30分加熱乾燥後、続いて120℃、1h真空乾燥し、23℃、50%RH下で24時間放置した物を試験片とした。剥離強度試験は、試験片塗装面とSUS板とを両面テープを用いて貼り合わせ、180°剥離を実施した(剥離幅25mm、剥離速度100mm/min)。
電池のサイクル試験は、CC−CV充電(上限電圧4.2V、電流1C、CV時間1.5時間、CC放電(下限電圧3.0V、電流1C)とし、いずれも60℃で実施した。容量維持率は、1サイクル目の放電容量に対する500サイクル目の放電容量の割合とした。
冷却管、温度計、攪拌機、滴下ロートを有するセパラブルフラスコに、イオン交換水160部およびアニオン性界面活性剤(三洋化成工業株式会社製、エレミノールJS−20(前記式(4)の構造式からなる化合物)、40%品)2部を仕込み、75℃に昇温した。予めエレミノールJS−20を10部、ハイテノール08E(ポリオキシエチレンアルキルエーテル硫酸エステル塩、第一工業製薬株式会社製)2部、スチレン250部、アクリル酸2−エチルヘキシル220部、メタクリル酸2−ヒドロキシエチル10部、ジビニルベンゼン1.5部、アクリル酸(80%品)15部、およびイオン交換水395部からなるモノマー乳化物を3時間かけて滴下した。同時に重合開始剤として過硫酸カリウム2部をイオン交換水50部に溶解したものを3時間かけて80℃で滴下重合した。滴下終了後、2時間熟成後冷却し、アンモニア水4.5部を添加して水性エマルジョンAを得た。得られた水性エマルジョンAの不揮発分は45.5%、粘度3000mPa・s、pH6.5であった。
界面活性剤としてエレミノールJS−20の代わりに、アニオン性界面活性剤(株式会社ADEKA製、アデカリアソープSR−10(前記式(1)の構造式からなる化合物))に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンBの不揮発分は45.4%、粘度3200mPa・s、pH6.6であった。
スチレン250部およびアクリル酸2−エチルヘキシル220部を、スチレン100部およびアクリル酸2−エチルヘキシル370部に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンCの不揮発分は44.8%、粘度2800mPa・s、pH6.4であった。
スチレン250部およびアクリル酸2−エチルヘキシル220部を、スチレン320部およびアクリル酸2−エチルヘキシル150部に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンDの不揮発分は44.9%、粘度2900mPa・s、pH6.5であった。
アクリル酸(80%品)15部を、アクリル酸(80%品)25部に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンEの不揮発分は45.3%、粘度6500mPa・s、pH6.2であった。
アクリル酸(80%品)15部を、イタコン酸12部に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンFの不揮発分は45.0%、粘度1050mPa・s、pH6.2であった。
スチレン250部およびアクリル酸2−エチルヘキシル220部を、スチレン250部およびアクリル酸ブチル220部に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンGの不揮発分は45.5%、粘度4200mPa・s、pH6.4であった。
スチレン250部およびアクリル酸2−エチルヘキシル220部を、スチレン60部およびアクリル酸2−エチルヘキシル410部に変えた以外は水性エマルジョンAの合成と同様な操作を行った。得られた水性エマルジョンHの不揮発分は44.5%、粘度2500mPa・s、pH6.4であった。
