Abstract

Description
電気化学系内におけるイオンの移動には、様々な方法を用いることができるが、主に、以下の手法が用いられる。
− 移動種についての高いイオン伝導性とともに、系の短絡を防止する極めて高い電気抵抗を有すること。
− 移動種について高い選択性を有すること。系の濃度分極を防ぐため、移動種は1種類であることが好ましい。
− 分離ができるだけ薄いこと。イオンの移動に起因した、IRドロップによるエネルギーロスをできる限り抑えるためである。
− 分離が優れた機械的強度を有すること。電気化学変換電池の組み立て及び作動中に分離部が突き破られるのを防ぐためである。
− セパレータが加工容易であること。例えば、焼結したセラミックス材料又はガラス/ガラスセラミックスの薄膜は、非常にもろく壊れやすいことから、非常に厳密な加工が必要となる場合がある。
− 分離材に接触する媒質に対して化学的安定性を有すること。
− 高い熱安定性を有すること。過熱時に短絡するのを防ぐためである。
現在、Liイオン電池用の標準的なセパレータ材は、ポリエチレン、ポリプロピレン又はこれらポリマーの組み合わせからなる多孔質親水化ポリマーフィルムである。セパレータ材は電解液で満たされており、そこで電極材料間のイオン移動が起こる。従来の電解液としては、炭酸エステルの混合物(少量の有機添加剤(表層形成剤)を含む場合もある)が挙げられ、そこにリチウム電導塩(例えばLiPF6)が溶解している。セパレータ材料は、それ自身はイオン伝導に関与せず、電極間の電気絶縁スペーサーとしてのみ機能する。現在用いられているLiイオン電池の充電状態における負極物質はリチウム化グラファイトであるが、リチウム化グラファイトは還元電位が低いため、使用される電解液の有機化合物が熱力学的に不安定となる。そのため、Liイオン電池の初回充電(形成)時には、電解液の一部がグラファイト粒子の表面上で還元されて、ポリマー薄膜(SEI、相間固体電解質)が形成される。SEIは、電気的に絶縁性であることから、非常に薄い膜厚で電解液の有機化合物がさらに還元されるのを防止することができる。また、SEIは、リチウムイオン伝導性であることから、リチウムイオンをグラファイトと電解液との間で移動させることができる。このような系の好ましい特徴としては、非常に薄い設計(9μmまで)、比較的優れた機械的強度、加工の容易さ、及び比較的高いイオン伝導性が挙げられる。また、このような材料の欠点としては、低い熱安定性(ポリオレフィンの融点は200℃未満である)、リチウム化グラファイトに対して電解液が熱力学的安定性を持たないこと、及びLi+イオン輸率が<1であることが挙げられる。
Na/S電池は、高温動作型蓄電池の一種であり、負極活物質が溶融ナトリウムである。溶融ナトリウムは、電気絶縁性且つナトリウムイオン伝導性のβ”−Al2O3焼結セラミックチューブ(セパレータ)と直接接触しており、それにより電池の正極液部から分離されている。カソード液部には、正極活物質(硫黄及び多硫化ナトリウム)が溶融状態で存在し、同様にセパレータと直接接触している。その結果、液体ナトリウム並びに硫黄及び多硫化ナトリウムの双方に対する熱力学的安定性、Na+伝導に対する高い選択性、高い熱安定性、特に高温状態での比較的高い選択的イオン伝導性、多結晶焼結セラミックの優れた機械的強度といった、セパレータとしての好ましい特徴が得られる。また、こうしたセパレータの欠点としては、分離層が厚いことや、非常に薄い平板状の焼結膜では加工が著しく制限され、わずかな曲げ応力でも破断してしまうことが挙げられる。
− 溶融状態で導入する方法。
− ポリマー溶液で導入した後、例えば減圧により溶媒を除去する方法。
− ポリマー粒子の懸濁液で導入した後、該粒子を焼結又は融解させる方法。
− ポリマーのオリゴマーを導入した後、架橋させる方法。
− アノード液部又はカソード液部である充填媒質と接触した時に化学反応を起こさないこと。
− 蒸発を防ぐため、非常に低い蒸気圧であること(したがって、特にイオン液体が好ましい)。
− アノード液部又はカソード液部である充填媒質と相溶性がないこと。
− イオン液体は、アノード液部又はカソード液部である充填媒質と相溶性がないことが求められる。
− セグメントは、好ましくは互いに咬合させることにより、機械的に連結される。
− アノード液又はカソード液である充填媒質と化学反応しないこと。
− Li2O−Al2O3−SiO2−P2O5−TiO2−GeO2:Li+伝導性ガラスセラミックス
− β−酸化アルミニウム:種々のイオンを伝導可能。(例えばLi+、Na+、K+、Ag+、H3O+、Tl+、Rb+、Pb2+、Ba+);特にNa+に高い伝導性を有する。
− β“−酸化アルミニウム:種々のイオンを伝導可能。(例えばLi+、Na+、K+、Ag+、H3O+、Tl+、Rb+、Pb2+、Ba+);特にNa+に高い伝導性を有する。
− Cu16Rb4I7Cl13:Cu+イオン伝導性。
− H3Mo12PO40・30H2O:プロトン伝導性。
− La0.95Sr0.05F2.95及びLaF3:F−イオン伝導性。
− Ag4RbI5:Ag+イオン伝導性。
− Li1.3Al0.3Ti1.7(PO4)3:Li+イオン伝導性。
− Li0.34La0.51TiO2.94:Li+イオン伝導性。
− NASICON(ナトリウム超イオン伝導体):Na+イオン伝導性。
− LISICON(リチウム超イオン伝導体):Li+イオン伝導性。
