【選択図】図1
Description
負極活物質を有する負極と、
酸素を正極活物質とする第1正極と、
前記第1正極に接触し、電子スピン共鳴分析で測定されたスピン密度が1019spins/g以上であるラジカル骨格を含む構造を有する化合物を含む非水電解液と、
前記非水電解液に接触し前記化合物を酸化する第2正極と、
を備えたものである。
負極活物質を有する負極と、酸素を正極活物質とする第1正極と、前記第1正極に接触し電子スピン共鳴分析で測定されたスピン密度が1019spins/g以上であるラジカル骨格を含む構造を有する化合物を含む非水電解液と、前記非水電解液に接触し前記化合物を酸化する第2正極とを備えた非水電解液空気電池の使用方法であって、
前記負極と前記第1正極とに接続して、前記非水電解液空気電池を放電させ、
前記第2正極を用いて前記化合物を酸化させ該酸化した前記化合物により前記非水電解液空気電池を充電させるものである。
カーボンペーパー(東レ製、TGP−H−060)を20mgとなるように切り取り、非水電解液リチウム空気電池の正極とした。負極には、直径10mm、厚さ0.5mmの金属リチウム(田中貴金属製)を用いた。これらを用いて図2に示した電気化学評価セル40を作製した。まず、SUS製のケーシング48に負極41を設置し、正極42との間にはリチウム伝導性固体電解質45(OHARA製)を設置した。負極41と固体電解質45との間には、非水電解液44(電解液A)を5mL注入した。電解液Aには、1Mのリチウムビス(トリフルオロメタンスルホニル)イミドを支持塩として含む、エチレンカーボネート30質量部とジエチルカーボネート70質量部とからなる溶液(関東化学製)を用いた。次に、N,N−ジメチル−N−メチル−N−(2−メトキシエチル)アンモニウムビス(トリフルオロメチルスルホニル)イミド(DEME−TFSI)25mLに支持塩としてリチウムビス(トリフルオロメチルスルホニル)イミド3.26gを溶解させ、0.32mol/kgの非水電解液を調製した(電解液B)。この非水電解液3.00mL中に酸化還元触媒として、4−メトキシ−2,2,6,6−テトラメチルピペリジン−1−オキシルフリーラジカル(MeO−TEMPO;化合物D)を55.88mg溶解させ,0.1Mの触媒濃度となる非水電解液46(電解液C)を調製した。固体電解質45と正極42の間に電解液Cを1mL注入した。正極42上から空気が流通可能な押さえ部材51で押し付けることにより、セルを固定した。押さえ部材51の上部にはガス溜め52を接続した。このようにして実験例1のリチウム空気電池を得た。なお、図示しないが、ケーシング48は正極42と接触する上部と負極41と接触する下部とに分離可能であり、上部と下部との間に絶縁樹脂が介在している。これより、正極42と負極41とは電気的に絶縁されている。
図2に示した電気化学評価セル40を用いて充電を行い、電解液Cに含まれる安定ラジカル化合物(酸化還元触媒)をすべて酸化した。この溶液を電解液Bで希釈し、0.01Mの濃度とした(電解液D)。別途、実験例1と同様に電気化学評価セルを作製し、実験例1と同様に放電を行ったあと、セル内の電解液Cを電解液Dの0.2mLと交換した。その後25℃で2〜20時間保存したあと、再び実験例1と同様に放電を行った。以上の放電、非水電解液の交換、電池セルの保存のサイクルを繰返し実施したものを実験例2とした。実験例2は、放電生成物を生成する放電時の正極(第1正極)と、酸化還元触媒を酸化する充電時の正極(第2正極)とを別にするため、図1に示した電池セルの第1正極及び第2正極の機能を再現することができる。
固体電解質と正極3との間に電解液Bを1mL注入した以外は、実験例1と同様にして充放電試験を実施した。実験例3は、非水電解液46に安定ラジカル化合物(酸化還元触媒)を含まないものである。
