Abstract
(EN) A battery (100) and an electronic device (200) using the battery (100). The battery (100) comprises a battery cell (10) and a shell (30). The shell (30) comprises a first shell body (31) and a second shell body (33), and an accommodation cavity (302) is formed by means of the enclosure of the first shell body (31) and the second shell body (33). The battery cell (10) comprises a battery cell body (11) and a tab (13) connected to the battery cell body (11), and the battery cell body (11) is located in the accommodation cavity (302). The shell (30) further comprises a third shell body (35) and a through groove (304) penetrating through the second shell body (33). The third shell body (35) is embedded into the through groove (304) and is fixedly connected to the second shell body (33), and the tab (13) extends out from the space between an inner wall of the through groove (304) and the third shell body (35), facilitating the reduction of the energy loss of the battery (100).
(FR) L'invention concerne une batterie (100) et un dispositif électronique (200) utilisant la batterie (100). La batterie (100) comprend un élément de batterie (10) et une coque (30). La coque (30) comprend un premier corps de coque (31) et un deuxième corps de coque (33), et une cavité de réception (302) est formée au moyen de l'enceinte du premier corps de coque (31) et du deuxième corps de coque (33). L'élément de batterie (10) comprend un corps d'élément de batterie (11) et une languette (13) reliée au corps d'élément de batterie (11), et le corps d'élément de batterie (11) est situé dans la cavité de réception (302). La coque (30) comprend également un troisième corps de coque (35) et une rainure traversante (304) pénétrant à travers le deuxième corps de coque (33). Le troisième corps de coque (35) est incorporé dans la rainure traversante (304) et est relié de manière fixe au deuxième corps de coque (33), et la languette (13) s'étend hors de l'espace entre une paroi interne de la rainure traversante (304) et le troisième corps de coque (35), ce qui facilite la réduction de la perte d'énergie de la batterie (100).
(ZH) 一种电池(100)和应用所述电池(100)的电子装置(200),所述电池(100)包括电芯(10)和外壳(30)。所述外壳(30)包括第一壳体(31)和第二壳体(33),所述第一壳体(31)和所述第二壳体(33)围设形成收容腔(302)。所述电芯(10)包括电芯本体(11)和连接所述电芯本体(11)的极耳(13),所述电芯本体(11)位于所述收容腔内(302)。所述外壳(30)还包括第三壳体(35)和贯穿所述第二壳体(33)的通槽(304)。所述第三壳体(35)嵌入所述通槽(304)内并与所述第二壳体(33)固定连接,所述极耳(13)从所述通槽(304)的内壁和所述第三壳体(35)之间伸出,有利于降低电池(100)的能量损失。
