Title (EN) BATTERY MODULE AND METHOD FOR MANUFACTURING SAME
(FR) MODULE DE BATTERIE ET SON PROCÉDÉ DE FABRICATION
(JA) 電池モジュール、および、その製造方法
Abstract:
(EN) A battery module (10) is provided with: a plurality of battery cells (11) each having a terminal (14); and a lead plate (41) that electrically connects the battery cells (11) through joining of a lead part (47) to the terminal (14) of each of the battery cells (11). The lead part (47) is made of an aluminum thin plate having aluminum purity of 99.0% or higher, the surface roughness Ra of the joined surface of the lead part (47) with respect to the terminal (14) is 10 µm or less, and the lead part (47) is electrically connected to the terminal (14) through solid-phase joining.
(FR) La présente invention concerne un module de batterie (10) qui est pourvu : d'une pluralité d'éléments de batterie (11) ayant chacun une borne (14) ; d'une plaque conductrice (41) qui connecte électriquement les éléments de batterie (11) par liaison d'une partie conductrice (47) à la borne (14) de chacun des éléments de batterie (11). La partie conductrice (47) est constituée d'une plaque mince en aluminium dont la pureté d'aluminium est supérieure ou égale à 99,0 %, la rugosité de surface Ra de la surface jointe de la partie conductrice (47) par rapport à la borne (14) étant inférieure ou égale à 10 µm, et la partie conductrice (47) étant électriquement connectée à la borne (14) par liaison en phase solide.
(JA) 電池モジュール(10)は、端子(14)をそれぞれ有する複数の電池セル(11)と、複数の電池セル(11)の各端子(14)にリード部(47)がそれぞれ接合されることによって電池セル(11)同士を電気的に接続するリード板(41)とを備える。リード部(47)はアルミニウム純度99.0%以上のアルミニウム薄板で構成され、リード部(47)の端子(14)に対する接合面の表面粗度Raが10μm以下であり、リード部(47)が固相接合によって端子(14)に電気的に接続されている。
