Title (EN) NEGATIVE ELECTRODE COMPOSITION FOR SECONDARY BATTERY AND SECONDARY BATTERY USING SAME
(FR) COMPOSITION D’ÉLECTRODE NÉGATIVE POUR ACCUMULATEUR ET ACCUMULATEUR L’UTILISANT
(JA) 二次電池用の負極組成物、およびこれを用いた二次電池
Abstract:
(EN) [Problem] To provide a secondary battery having a short charging time and a high charge-and-discharge efficiency. [Solution] This secondary battery 10 is produced by using a negative electrode composition, and a positive electrode composition that includes active carbon and a binder, the negative electrode composition including: carbon black as a carbon-based conductive material; polyimide as a binder; and silicon powder. This secondary battery 10 has a shorter charging time and a higher charge-and-discharge efficiency than secondary batteries which employ, as a positive active material, a conventional known active material for a lithium ion battery.
(FR) L’invention aborde le problème de réalisation d’un accumulateur ayant une courte durée de charge et un haut rendement de charge et de décharge. La solution selon l’invention consiste en un accumulateur (10) qui est produit au moyen d’une composition d’électrode négative, et d’une composition d’électrode positive qui inclut du carbone actif et un liant, la composition d’électrode négative incluant : du noir de carbone en tant que matériau conducteur à base de carbone ; du polyimide en tant que liant ; et de la poudre de silicium. Cet accumulateur (10) a une durée de charge plus courte et un rendement de charge et de décharge plus élevé que celui des accumulateurs qui emploient, en tant que matériau actif positif, un matériau actif connu conventionnel pour une batterie lithium-ion.
(JA) 【課題】充電時間が短く、充放電の効率の高い二次電池を提供する。 【解決手段】カーボンブラックを炭素系の導電材として含み、ポリイミドを結着剤として含み、さらにシリコンパウダーを含む負極組成物と、活性炭と結着剤とを含む正極組成物を用いて作成した二次電池10とすることで、正極活物質として従来公知のリチウムイオン電池用の活物資を採用した二次電池よりも、充電に要する時間が短く、充放電の効率が高い二次電池となる。
