Title
(EN) NONAQUEOUS SECONDARY BATTERY
(FR) ACCUMULATEUR NON AQUEUX.
(JA) 非水系2次電池
Abstract
(EN) A nonaqueous secondary battery comprising a positive electrode, a negative electrode and a nonaqueous electrolyte, wherein the negative electrode contains as a negative electrode active substance a material constituted of a 70:30 to 40:60 (mass ratio) mixture of polycyclic aromatic hydrocarbon, the polycyclic aromatic hydrocarbon obtained by subjecting a raw material composed mainly of pitch to thermal reaction, and graphitized mesocarbon microbeads and wherein the positive electrode contains as a positive electrode active substance a lithium nickel double oxide of specified composition. Thus, this nonaqueous secondary battery can be easily produced and exhibits a high volume energy density, excelling in cycle characteristics and safety.
(FR) L'invention porte sur un accumulateur non aqueux comprenant une anode, une cathode et un électrolyte non aqueux, la cathode contenant comme substance active un matériau constitué d'un mélange d'hydrocarbure aromatique polycyclique (rapport en poids) compris entre 70 : 30 et 40 : 60, l'hydrocarbure aromatique polycyclique étant obtenu en soumettant à une réaction thermique une matière première principalement constituée de brai, et des microbilles de mésocarbone graphitisées. L'anode contient comme substance active un double oxyde lithium-nickel d'une composition spécifique. Il est ainsi facile de produire un accumulateur non aqueux présentant un volume élevé de densité d'énergie, et d'excellentes qualités de recyclage et de sécurité.
(JA) 正極、負極および非水系電解質を具備する非水系2次電池において、上記負極がピッチを主成分とする原料を熱反応に供することにより得られる多環芳香族系炭化水素と黒鉛化メソカーボンマイクロビーズとを質量比70:30乃至40:60の範囲で混合した材料を負極活物質とすると共に、特定の組成を有するリチウムニッケルの複合酸化物を正極活物質としている。このため、非水系2次電池は、製造が容易であり、体積エネルギー密度が高く、サイクル特性及び安全性に優れている。
