Description
米国政府は、本発明における払い込み済実施許諾契約と、米国エネルギー省により授与された認可番号DEFG14378−003およびDEFG03945541の条件により与えられた通り、制限された状況において正当で妥当な条件で特許権者に対し他人に使用許諾することを要求する権利を有する。
本非仮特許出願は、2005年1月19日にシャオ・ガン・サンらにより出願された、「再充電可能なリチウム電池用の新規なスルホン電解質」と題する仮出願シリアル番号60/645,536の優先権を主張する。
本発明は、一般的に、電流発生装置に用いるための非水電解質溶媒に係り、より特には、電流発生装置に用いて好適な、非対称で非環状のスルホンを有する非水電解質溶媒に関する。
電池は、携帯用途に用いるための多くの種類のモーターおよび電子装置に電気を供給するためによく用いられている。電池は、再充電可能なタイプであるか、使い捨て(1回限りの使用)タイプであり得る。電池は、携帯電子システム中の集積回路のために動作電力を提供するか、工業的用途のためにモーターを駆動するための動電力を提供する。
1つの態様において、本発明は、1種またはそれ以上のイオン性電解質塩、および一般式:R1−SO2−R2の1種またはそれ以上の非対称で非環状のスルホンを含む非水電解質溶媒を含む、電流発生装置に使用するための電解質要素(electrolyte element)である。R1基は、1〜7個の炭素原子を有する、直鎖もしくは分枝鎖のアルキル基または部分的にもしくは完全にフッ素化されたアルキル基である。R2基は、R1基とは組成が異なり、1〜7個の炭素原子を有する、直鎖もしくは分枝鎖の、または部分的にもしくは完全にフッ素化された直鎖もしくは分枝鎖の、酸素含有アルキル基である。
本発明を、同様の数字が同じまたは類似の要素を表している図面を参照して以下の記述において1またはそれ以上の態様で説明する。本発明を、本発明の目的を達成するための最良の形態の観点から記述するが、添付の請求の範囲により規定される発明の精神および範囲並びに以下の開示および図面により裏付けられるそれらの均等物の範囲内に含まれ得る代替、修飾および均等物をカバーすることが意図されていることが当業者に十分理解されるであろう。
