Title (EN) NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池
Abstract:
(EN) This non-aqueous electrolyte secondary battery is provided with: an electrode group in which a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode are wound; a tape for fixing at least the winding end portion of the electrode group; and a non-aqueous electrolyte. The negative electrode includes lithium metal and/or a lithium alloy in at least a charged state. The tape has a tensile strength set to 20N/10 mm or lower when the elongation rate is 200% or higher.
(FR) L'invention concerne une batterie secondaire à électrolyte non aqueux comprenant : un groupe d'électrodes dans lequel une électrode positive, une électrode négative et un séparateur intercalé entre l'électrode positive et l'électrode négative sont enroulés ; une bande pour fixer au moins la partie d'extrémité enroulée du groupe d’électrodes; et un électrolyte non aqueux. L'électrode négative comprend un métal lithium et/ou un alliage de lithium dans au moins un état chargé. La bande a une résistance à la traction fixée à au maximum 20N/10 mm lorsque le taux d'allongement est supérieur ou égale à 200 %.
(JA) 非水電解質二次電池は、正極と、負極と、前記正極および前記負極の間に介在するセパレータとが巻回された電極群と、前記電極群の少なくとも巻き終わり端部を固定するテープと、非水電解質と、を備える。少なくとも充電状態において、前記負極は、リチウム金属および/またはリチウム合金を含む。前記テープは、伸び率が200%以上のときの引張強度が20N/10mm以下である。
