pyrocarbonatesとは 意味・読み方・使い方

In the nonaqueous electrolytic solution secondary battery having a negative electrode and a positive electrode containing a graphite which has a face distance (d002) of 0.338 nm or less and an electrolytic solution of organic solvent series containing a nonaqueous solvent, among solvent components of the electrolytic solution, not less than 30% of volume ratio is constituted from phosphates and pyrocarbonates is made to be contained.例文帳に追加

面間隔（ｄ_002 ）が０．３３８ｎｍ以下の黒鉛を含む負極、正極および有機溶媒を含む非水溶媒系の電解液を有する非水電解液二次電池において、上記電解液の溶媒成分のうち体積比で３０％以上をリン酸エステルで構成し、かつ該電解液中にピロカーボネート類を含有させる。 - 特許庁

As the content of pyrocarbonates, 1-15% by the volume ratio is preferable, and in addition, it is preferable that at least one kind of aliphatic fluorinated ether is made to be contained in the nonaqueous electrolytic solution, and that the added content of the aliphatic fluorinated ether and phosphates is made not less than 60% by the volume ratio in the solvent component of nonaqueous electrolytic solution.例文帳に追加

上記ピロカーボネート類の非水電解液中の含有率としては、体積比で１〜１５％が好ましく、また、上記非水電解液中には少なくとも１種の鎖状のフッ素化エーテルを含有させ、その鎖状のフッ素化エーテルとリン酸エステルとをあわせた含有率を非水電解液の溶媒成分中において体積比で６０％以上にすることが好ましい。 - 特許庁
