Title (EN) NONAQUEOUS SECONDARY CELL
(FR) PILE RECHARGEABLE NON AQUEUSE
(JA) 非水系二次電池
Abstract:
(EN) A nonaqueous secondary cell provided with: a positive electrode provided with a positive-electrode current-collecting substrate and a positive-electrode active material layer formed thereon, the positive-electrode active material layer being able to absorb or discharge lithium; a negative electrode provided with a negative-electrode current-collecting substrate and a negative-electrode active material layer formed thereon, the negative-electrode active material layer being able to absorb or discharge lithium; a separator interposed between the positive and negative electrodes; and a nonaqueous electrolyte solution. The nonaqueous electrolyte solution contains a sulfonyl imide electrolyte and a nonaqueous organic solvent. An electroconductive protective layer obtained by dispersing an electroconductive carbon material in a binder resin is formed on one or both surfaces of the positive-electrode current-collecting substrate and/or the negative-electrode current-collecting substrate. Regardless of whether the nonaqueous electrolyte solution including the sulfonyl imide electrolyte is used, the nonaqueous secondary cell has good cycle characteristics and high output characteristics.
(FR) La présente invention concerne une pile rechargeable non aqueuse qui comporte : une électrode positive pourvue d'un substrat collecteur de courant d'électrode positive et d'une couche de matériau actif d'électrode positive formée sur cette dernière, la couche de matériau actif d'électrode positive étant capable d'absorber ou de rejeter du lithium ; une électrode négative pourvue d'un substrat collecteur de courant d'électrode négative et d'une couche de matériau actif d'électrode négative formée sur cette dernière, la couche de matériau actif d'électrode négative étant capable d'absorber ou de rejeter du lithium ; un séparateur intercalé entre l'électrode positive et l'électrode négative ; et une solution électrolytique non aqueuse. La solution électrolytique non aqueuse contient un électrolyte d'imide de sulfonyle et un solvant organique non aqueux. Une couche de protection électroconductrice obtenue par dispersion d'un matériau à base de carbone électroconducteur dans une résine liante est formée sur une ou les deux surfaces du substrat collecteur de courant d'électrode positive et/ou du substrat collecteur de courant d'électrode négative. Que la solution électrolytique non aqueuse comprenant l'électrolyte d'imide de sulfonyle soit utilisée ou non, la pile rechargeable non aqueuse présente de bonnes caractéristiques de cycle et des caractéristiques de sortie élevées.
(JA) 正極集電基板およびその上に形成されたリチウムを吸蔵・放出可能な正極活物質層を備える正極と、負極集電基板およびその上に形成されたリチウムを吸蔵・放出可能な負極活物質層を備える負極と、これら正負極間に介在するセパレータと、非水系電解液とを備えて構成され、非水系電解液が、スルホニルイミド系電解質と、非水系有機溶媒とを含み、正極集電基板および負極集電基板のいずれか一方または双方の表面上に、バインダー樹脂中に導電性炭素材料が分散してなる導電性保護層が形成されている非水系二次電池は、スルホニルイミド系電解質を含む非水電解液を用いているにもかかわらず、サイクル特性が良好であり、出力特性も高い。
