Title (EN) WOUND-TYPE ACCUMULATOR
(FR) ACCUMULATEUR DE TYPE ENROULÉ
(JA) 捲回型蓄電源
Abstract:
(EN) A wound-type accumulator which is simplified in the layout of lithium ion sources and shortened in time spent on injecting a nonprotonic organic solvent electrolytic solution and on predoping, so as to allow quick completion of assembly and obtain high productivity.  The wound-type accumulator is provided with: a cylindrical wound electrode unit which has cathode and anode strips and is configured by winding from one end an electrode stack comprised of a stack of the cathode and anode with a separator disposed therebetween; and an electrolytic solution.  In this wound-type accumulator, the cathode and/or anode is doped with lithium ions and/or anions by means of electrochemical contact of the cathode and/or anode with a lithium ion source.  At the cathode, a cathode gap section is formed, and at least one lithium ion source is arranged at the cathode gap section or at a position opposing the cathode gap section at the anode, in a state not contacting the cathode.
(FR) L'invention concerne un accumulateur dont la configuration des sources d'ion lithium est simplifiée et dont le temps passé à injecter une solution électrolytique de solvant organique non protonique et à prédoper est réduit afin de permettre un assemblage rapide et d'obtenir une productivité élevée. L'accumulateur de type enroulé comporte : une électrode enroulée cylindrique qui comporte des bandes de cathode et d'anode et qui est configurée en enroulant depuis une extrémité un empilement d'électrode constitué d'un empilement des cathode et anode avec un séparateur disposé entre elles ; et une solution électrolytique. Dans cet accumulateur de type enroulé, la cathode et/ou l'anode sont dopées aux ions lithium et/ou aux anions au moyen de contact électrochimique de la cathode et/ou de l'anode avec une source d'ions lithium. À la cathode, une section d'espace de cathode est formée, et au moins une source d'ions lithium est disposée dans la section d'espace de cathode ou à une position opposée à la section d'espace de cathode à l'anode, dans un état sans contact avec la cathode.
(JA)  本発明は、リチウムイオン供給源の配置の簡便化、並びに、非プロトン性有機溶媒電解質溶液の注液時間およびプレドープ時間の短縮化が図られ、従って、短時間で組立を完了させることができて高い生産性が得られる捲回型蓄電源を提供することを目的とする。  本発明の捲回型蓄電源は、帯状の正極と負極とを有し、正極および負極がセパレータを介して積重されてなる電極積重体が、その一端から捲回されて構成された筒状の電極捲回ユニット、および、電解液を備えてなり、負極および/または正極とリチウムイオン供給源との電気化学的接触によって、リチウムイオンおよび/またはアニオンが負極および/または正極にドーピングされるものであって、正極に正極間隙部が形成され、前記正極間隙部、または、負極における当該正極間隙部に対向する位置に、当該正極と接触しない状態に少なくとも一つのリチウムイオン供給源が設けられることを特徴とする。
