Abstract
Description
本開示は、再充電可能バッテリのための電解質として有用な組成物、及びそれらを調製し、用いるための方法に関する。
様々な電解質溶液が二次電池における使用に導入されてきた。例えば、E.Markevich、他、Journal of The Electrochemical Society,160(10)A1824−A1833(2013)、及びKang Xu、Chem.Rev.2004,104,4303−4417 4303に、このような組成物が記載されている。
いくつかの実施形態では、電解質組成物が提供される。組成物は酢酸エチルと1つ以上のリチウム塩とを含む。酢酸エチルは電解質組成物の総体積に対して少なくとも50体積%の量で電解質組成物中に存在する。
電子デバイスの急速な発展は、燃料電池、コンデンサ、及びバッテリシステムなどの電気化学デバイスに対する市場需要を増大させた。特に、バッテリシステムに対する需要に応じて、実用的な再充電可能リチウムイオンバッテリが積極的に研究されている。これらのシステムは通例、リチウム金属、リチオ化炭素、又は合金を負極(アノード)として利用することに基づく。
様々な温度における電解質の伝導度を判定した。電解質は、以下の表1に略述されているとおりに配合した。電解質の伝導度は、YSI Incorporated(モデル3403)からの伝導度セル、及び1.0/cmのセル定数Kを用いて測定した。以下の表1に示される伝導度の結果は、酢酸エチルを含む電解質が、特に、低温において、比較例(CE)よりも高い伝導度を有したことを指示する。
面積比インピーダンス(Area SpecificImpedance)=ASI(オーム.cm2)=電圧変化(V)x電流(アンペア、停止前)x2.01cm2(ここで、2.01cm2は電極有効面積である)。放電の最後から10ミリ秒(0.1秒)の停止、及び15分の停止の後におけるセルの電圧変化から、セルインピーダンスの2つの値を算出した。
