Abstract
This invention relates to a negative electrode for non-aqueous electrolyte secondary batteries that uses organic electrolyte made form an organic solvent solution of Li salt. More specifically speaking, a highly reliable non-aqueous electrolyte secondary battery is realized by employing a negative electrode of high capacity and excellent cycle characteristics, wherein an active material holder composed of powdered metal, carbon, sulfide, oxide, etc. absorbs Li by charge and desorbes it by discharge or wherein a suitable polymer is used as a binder of the mixture comprising said active material holder and a conductive material. This invention greatly improves capacity and charge and discharge cycle life of not only a coin type cell but also a cylindrical cell, in which a thin and long strip type electrode plate is used and cycle characteristics are more critical.
