Abstract
(EN)
 The present invention provides a lithium ion cell free of internal short-circuiting. A lithium ion cell having a cell capacity of 20 Ah or more, wherein the lithium ion cell is aged at 3.75-4.2 V for 21 days or more. A lithium ion cell in which a differential voltage ΔV between a cell voltage V1 on the 14th day of aging and a cell voltage V2 on the 21st day of aging is less than 13 mV is provided as a lithium ion cell free of internal short-circuiting.
(FR)
L'invention fournit une batterie au lithium-ion sans courts-circuits internes. La batterie au lithium-ion de l'invention présente une capacité de batterie supérieure ou égale à 20Ah, et est soumise à un vieillissement de 21 jours ou plus entre 3,75 et 4,2V. Plus précisément, l'invention fournit en tant que batterie au lithium-ion sans courts-circuits internes, une batterie au lithium-ion dont la tension différentielle (ΔV) entre une tension de batterie (V1) au quatorzième jour de vieillissement et une tension de batterie (V2) au vingt et unième jour, est inférieure à 13mV.
(JA)
 内部短絡のないリチウムイオン電池を提供する。電池容量が20Ah以上のリチウムイオン電池であって、リチウムイオン電池を3.75~4.2Vで21日間以上エージングする。エージング14日目の電池電圧V1と21日目の電池電圧V2との差電圧ΔVが13mV未満であるリチウムイオン電池を内部短絡のないリチウムイオン電池として提供する。
