    Materials with high ionic conductivity are attracting a great deal of attention because they are indispensable for improving the performance of batteries, sensors, and capacitors. Solid electrolytes, in particular, have a potential to compensate for the shortcomings of liquid electrolytes, and are the subject of intense research and development worldwide. One of the big characteristics of glass is its high formability. Here we are focusing on glass-electrolytes. Differences between “superionic conductive glasses” and “ordinary glasses”, as well as the mixed alkali effect will be overviewed. In addition, glasses can retain large residual stress inside that can reach the order of several GPa depending on the cooling conditions. These residual stresses also affect ionic conductivity. Recent results on the application of glass formability and softening fluidity to the formation of interfaces in all-solid-state batteries, and to ion emission from sharpened glasses are reviewed.

  • Hydrogen adsorption and electronic structural calculation of a polymer-derived SiCH membrane with a unique affinity for molecular hydrogen International journal

    In order to understand the hydrogen affinity of polymer-derived SiCH membranes, the amount of adsorbed hydrogen molecules was measured near room temperature, and the stabilization energy for hydrogen adsorption was also calculated by first-principles calculations using the MP2 method. The energies of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), the dipole moment of model molecules as well as the charge of the molecular hydrogen, and those relations to the hydrogen molecule affinity were investigated. A linear relationship was found between LUMO energy values and the minimum stabilization energy. It is suggested that a hydrocarbon ring (pore entrance) less than 1 nm on the surface of the SiCH membrane is important as an adsorption site of a hydrogen molecule.

    電導性を有する圧子を電極としても利用することで、圧子圧入と同時にインピーダンス測定を実施する電気化学圧子圧入法について研究しています。4GPaを超える局所高圧力場でのYSZの電気抵抗と応力・ひずみの関係を同時測定しました。有限要素法(COMSOL)による圧力場と電場のシミュレーションから、酸化物イオンが伝導する際の活性化体積を一回の圧入から決定することに成功しました。

    溶融法で作製したガラスはプロトン(=OH基)濃度が低く、ガラスのプロトン伝導性は一般的に非常に低いです。以前に我々は燃料電池発電雰囲気に曝されることでガラスのプロトン伝導性が向上することを見出しています。燃料電池発電雰囲気を模擬した独自開発のin-situ赤外線分光装置を用いて、発電下でガラスのプロトン濃度が上昇するプロトン注入効果を初めて定量的に明らかにしました。論文では放射光X線による構造解析と合わせてプロトン注入を議論しています。

    SiO2(シリカ)はSiが4つの酸素で囲まれていますが、4つのうち一つをフェニル基に置き換えたものがフェニルシルセスキオキサン(PSQ)と呼ばれます。このPSQ粒子はゾル-ゲル法によって合成でき、粒子をガラス転移温度以上で加熱プレスすることで透明なバルク体に転移し、また絶縁性も比較的高いです。粒子→バルク転移時の変形挙動をin-situ解析したところ、粒子間にボイドが存在する場合は粘弾性挙動を示すのに対して、ボイドフリーのものは弾性変形すること、またボイドフリーの方がより高い絶縁耐圧を示すことを実験的に明らかにしました。
