Title (EN) ADDITIVE, PREPARATION METHOD THEREFOR AND LITHIUM ION BATTERY CONTAINING SAME
(FR) ADDITIF, SON PROCÉDÉ DE PRÉPARATION ET BATTERIE AU LITHIUM-ION LE CONTENANT
(ZH) 一种添加剂,其制备方法及含有所述添加剂的锂离子电池
Abstract:
(EN) Disclosed is an additive, in particular an additive selected from at least one of the compounds of formula (I). Disclosed is also a method for preparing the additive and a lithium ion battery containing the additive. The additive of the present application facilitates the formation of a stable SEI film on the electrode surface of a lithium ion battery, prevents the co-insertion of solvent molecules and inhibits the further reaction between the negative electrode and the electrolyte solution. The additive also can form a surface film on the electrode surface to isolate the air, thereby having a stronger flame retardant effect and enhancing the rate performance, cycle performance and safety of the battery.
(FR) L'invention concerne un additif, en particulier un additif choisi parmi au moins l'un des composés de formule (I). L'invention concerne également un procédé de préparation de l'additif et une batterie au lithium-ion contenant l'additif. L'additif de la présente invention facilite la formation d'un film SEI stable sur la surface d'électrode d'une batterie au lithium-ion, empêche la co-insertion de molécules de solvant et inhibe la réaction supplémentaire entre l'électrode négative et la solution d'électrolyte. L'additif peut également former un film de surface sur la surface d'électrode pour isoler l'air, ce qui a un effet ignifugeant plus fort et améliore les performances de debit, les performances de cycle et la sécurité de la batterie.
(ZH) 本申请涉及一种添加剂,具体讲,添加剂选自如式(I)所示化合物中的至少一种。本申请还涉及该添加剂的制备方法及含有该添加剂的锂离子电池。本申请的添加剂有助于在锂离子电池的电极表面形成稳定的SEI膜,阻止溶剂分子的共嵌入,抑制负极与电解液的进一步反应;还可以在电极表面形成表面膜以隔绝空气,从而发挥更强的阻燃效果,提升电池的倍率性能、循环性能和安全性。
