Abstract
(EN) The present application discloses an electrochemical device and an electric device. The electrochemical device comprises an electrode assembly and a housing accommodating the electrode assembly; the housing comprises a first housing and a second housing fixedly connected to the first housing, and at least one of the first housing and the second housing is provided with a notch; the electrode assembly comprises a tab, the tab extends from the notch to the outside of the housing, and the notch is filled with a sealing material. The electrochemical device of the present application has high sealing reliability, and the sealing manner of filling the notch with a sealing material occupies less space, increasing the energy density of the electrochemical device.
(FR) La présente invention concerne un dispositif électrochimique et un dispositif électrique. Le dispositif électrochimique comprend un ensemble électrode et un boîtier logeant l'ensemble électrode ; le boîtier comprend un premier boîtier et un second boîtier relié à demeure au premier boîtier, et au moins un boîtier parmi le premier boîtier et le second boîtier est pourvu d'une encoche ; l'ensemble électrode comprend une languette, la languette s'étend de l'encoche vers l'extérieur du boîtier, et l'encoche est remplie d'un matériau d'étanchéité. Le dispositif électrochimique de la présente invention présente une fiabilité d'étanchéité élevée, et le mode d'étanchéité de remplissage de l'encoche dotée d'un matériau d'étanchéité occupe moins d'espace, ce qui augmente la densité énergétique du dispositif électrochimique.
(ZH) 本申请公开了一种电化学装置及用电装置,该电化学装置包括电极组件及容纳所述电极组件的壳体,所述壳体包括第一壳体及与所述第一壳体固定连接的第二壳体,所述第一壳体与所述第二壳体中的至少一者设置有槽口,所述电极组件包括极耳,所述极耳从所述槽口伸出至所述壳体的外侧,所述槽口填充有密封材料。本申请的电化学装置密封可靠性高,由密封材料填充槽口的密封方式占用空间低,可提升电化学装置的能量密度。
