電極と電解質の調製による非プロトン性Li-O2電池の電気化学的試験のためのプロトコルと、頻繁に使用される特性評価方法の紹介がここで紹介されています。

この手順の全体的な目標は、電気化学的試験や電池材料の特性評価など、非プロトン性リチウム酸素電池の定期試験の体系的かつ効率的な配置を実証することです。このプロトコルには、非プロトン性リチウム酸素電池のメカニズムの研究、および活物質または電極触媒、カソード、非プロトン性電解質、および負極材料などの電池材料の開発が含まれます。このプロトコルの主な利点は、窒素、二酸化炭素、大気中の水分など、リチウム酸素電池の電気化学反応に影響を与える可能性のある成分が含まれていることです。

また、水酸化リチウムや炭酸リチウムなどの副産物も削減します。この手順を開始するには、事前に準備したカソード材料とポリフッ化ビニリデン(PVDF)を4対1の重量比で混合します。混合物の重量の約3倍でMPを追加します。
