Description
実施の形態1における電池は、正極と、負極と、電解液と、を備える。
スチレンブタジエンゴム(SBR)を結着剤として用いて、銅箔上に黒鉛(日立化成製MAG)を塗布した。これを乾燥した後、2x2cmに打ち抜いた。これを負極とした。
電解液に添加する2,2’ビピリジルの量を、それぞれ、変えた。
電解液に2,2’ビピリジルを、添加しなかった。
実施例1〜7および比較例1の試験用セルをそれぞれ用いて、2mAの定電流で、充放電を実施した。
実施例1と比較例1との対比から、実施例1(2,2’ビピリジル/黒鉛モル比が4.091×10−6の場合)の初回充放電効率は、約96.3%であり、比較例1(2,2’ビピリジルが無添加(2,2’ビピリジル/黒鉛モル比=0)の場合)の初回充放電効率である約94.8%よりも向上していることが分かる。
