Abstract:
(EN) According to the present embodiment, a non-aqueous electrolyte cell is provided with a positive electrode, a negative electrode, and a non-aqueous electrolyte. The negative electrode contains an active material and a binder. The active material contained in the negative electrode contains monoclinic crystal titanium dioxide, or Li4+aTi5O12 (where –0.5 ≤ a ≤ 3), and the binder contained by the negative electrode contains a polyvinylidene fluoride having a molecular weight of 400,000 to 1,000,000. The negative electrode satisfies equation (I) below. The non-aqueous electrolyte contains at least one of difluorophosphate or monofluorophosphate. 0.1 ≤ (P2/P1) ≤ 0.4 (I), wherein P1 is the peak intensity that appears within a range of 689 to 685 eV of the spectrum obtained using photoelectron spectroscopy on the surface of the negative electrode, and P2 is the peak intensity that appears within a range of 684 to 680 eV in said spectrum.
(FR) Selon un mode de réalisation, la présente invention concerne une pile à électrolyte non aqueux comprenant une électrode positive, une électrode négative et un électrolyte non aqueux. L'électrode négative contient un matériau actif et un liant. Le matériau actif contenu dans l'électrode négative contient du dioxyde de titane cristallin monoclinique, ou Li4+aTi5O12 (avec -0,5 ≤ a ≤ 3), et le liant contenu dans l'électrode négative contient un polyfluorure de vinylidène présentant un poids moléculaire de 400.000 à 1.000.000. L'électrode négative satisfait l'équation (I) ci-dessous. L'électrolyte non aqueux contient un difluorophosphate et/ou un monofluorophosphate. 0,1 ≤ (P2/P1) ≤ 0,4 (I), P1 étant l'intensité maximale qui apparaît dans une plage de 689 à 685 eV du spectre obtenu au moyen d'une spectroscopie photoélectronique sur la surface de l'électrode négative, et P2 étant l'intensité maximale qui apparaît dans une plage de 684 à 680 eV dans ledit spectre.
(JA) 実施形態によれば、非水電解質電池は、正極と、負極と、非水電解質とを具備する。負極は、活物質とバインダーとを含む。負極の含む活物質は、単斜晶型二酸化チタンまたはLi4+aTi12(ここで、-0.5≦a≦3)を含み、負極の含むバインダーは、分子量が40万以上100万以下であるポリフッ化ビニリデンを含む。そして、負極は、下記式(I)を満たす。非水電解質は、ジフルオロリン酸塩またはモノフルオロリン酸塩の少なくともいずれか一方を含む。 0.1≦(P2/P1)≦0.4 (I)ここで、P1は負極の表面に対する光電子分光測定によって得られるスペクトルにおいて689~685eVの範囲内に現れるピークの強度、P2は該スペクトルにおいて684~680eVの範囲内に現れるピークの強度である。
