Abstract
Description
(正極) O2 + 4e- → 2O2-
4Li+ + 2O2- → 2Li2O
2Li+ + 2O2- → Li2O2
また、充電時には、次の式に示すように前記正極において酸化リチウムまたは過酸化リチウムからリチウムイオンと電子と酸素とが生成し、生成したリチウムイオンは前記電解質層を透過して負極に移動する。そして、負極では前記リチウムイオンが電子を受け取り、金属リチウムとして析出する。析出した金属リチウムは、前記グラファイトに吸蔵(インターカレーション)される。
Li2O2 → 2Li+ + O2 + 4e-
(負極) 4Li+ +4e- → 4Li
前記リチウムイオン酸素電池によれば、前記正極は大気中の酸素を活物質とするので、正極活物質の質量に制約を受けることが無く、質量当たりのエネルギー密度を増大させることができる。
Li2O2 → 2Li+ + 2O-
(負極) Li+ +e- → Li
また、放電時には、次の式に示すように、負極3において金属リチウムがイオン化してリチウムイオンと電子とが生成する。生成したリチウムイオンは、前記炭素質材料から放出(デインターカレーション)され、電解質層4を介して正極2に移動する。一方、正極2においては、前記酸素貯蔵材料から化学結合の解離により放出され、或いはその表面から脱着されることにより取出された酸素が、負極3から移動して来た前記リチウムイオンと共に電子を受け取って、過酸化リチウム又は酸化リチウムを生成する。そこで、負極3と正極2とを導線(図示せず)で接続することにより、電気エネルギーを取り出すことができる。
(正極) 4Li+ + O2 + 4e- → 2Li2O
2Li+ + O2 + 2e- → Li2O2
