Title (EN) LITHIUM METAL BATTERY
(FR) BATTERIE LITHIUM MÉTAL
(ZH) 锂金属电池
Abstract:
(EN) A lithium metal battery, comprising a hard housing (1), a hard support column (2) that is located within the hard housing (1), and a wound battery core (3) that is wound between the hard housing (1) and the support column (2); the housing (1) is a cylinder having an opening at one end, and the wound battery core (3) comprises a positive electrode (31), a negative electrode (32) containing lithium, and an electrolyte located between the negative electrode (32) and the positive electrode (31); the housing (1) and the support column (2) jointly form a space that is used for limiting the wound battery core (3). By means of the present invention, high energy density may be achieved.
(FR) L'invention concerne une batterie lithium métal, comprenant un boîtier rigide (1), une colonne de support rigide (2) qui est située à l'intérieur du boîtier rigide (1), et un noyau de batterie enroulé (3) qui est enroulé entre le boîtier rigide (1) et la colonne de support (2); le boîtier (1) est un cylindre ayant une ouverture à une extrémité, et le noyau de batterie enroulé (3) comprend une électrode positive (31), une électrode négative (32) contenant du lithium, et un électrolyte situé entre l'électrode négative (32) et l'électrode positive (31); le boîtier (1) et la colonne de support (2) forment conjointement un espace qui est utilisé pour limiter le noyau de batterie enroulé (3). Au moyen de la présente invention, une densité d'énergie élevée peut être obtenue.
(ZH) 一种锂金属电池,包括硬质的壳体(1)、位于所述硬质的壳体(1)内的硬质的支撑柱(2)和卷绕在所述壳体(1)和所述支撑柱(2)之间的电池卷芯(3),所述壳体(1)为一端具有开口的圆柱体,所述电池卷芯(3)包括正极(31)、含有锂的负极(32)和位于所述负极(32)和所述正极(31)之间的电解质,所述壳体(1)和所述支撑柱(2)共同形成用于约束所述电池卷芯(3)的空间。能够实现较高的能量密度。
