Abstract
Description
「セル」または「電池セル」は一般に、電気化学セルを指し、これは、化学反応から電気エネルギーを生成するか、または電気エネルギーの導入を通じて化学反応を促進することができるデバイスである。電池は、1つまたは複数のセルを含み得る。
乾燥および密封された単結晶Li[Ni0.5Mn0.3Co0.2]O2(NMC532)||Cuパウチセル(4.5Vで260mAh)は、Li-FUN Technology(Xinma Industry Zone、Golden Dragon Road、Tianyuan District、Zhuzhou City、Hunan Province、China、412000)から入手した。正極は94質量%の活性材料からなり、片面コーティング活材料電極投入量は16mg/cm2であった。正極を3.5g/cm3の密度に圧縮した。電解質に使用される試薬は、FEC(BASF、純度99.4%)、DEC(BASF、純度>99%)、DMC(BASF、純度>99%)、LiPF6(BASF、純度99.9%)、LiDFOB(Capchemまたは3M)、およびLiBF4(Capchem)を含み、電解質成分は、精密天秤を使用してアルゴン充填グローブボックス内で混合した。所望の電解質を充填する前に、パウチセルを切り開き、真空下100℃で14時間乾燥させて残留水分を除去した。その後、パウチセルをアルゴン充填グローブボックス内で0.5mLの電解質で満たし、-90kPa(大気圧に対して)の圧力で真空下でパウチシーラー(MSK-115A Vacuum Sealing Machine)で密封した。充填後、セルを1.5Vで24時間保持して湿潤を促進し、続いてサイクルのために40℃の温度ボックスに移した。
