Title
(EN) LITHIUM METAL SUPPORT, PREPARATION METHOD THEREFOR AND USE THEREOF
(FR) SUPPORT AU LITHIUM-MÉTAL, SON PROCÉDÉ DE PRÉPARATION ET SON UTILISATION
(ZH) 金属锂支撑体及其制备方法与应用
Abstract
(EN)
The lithium affinity of the surface a current collector itself is improved, and the full utilization of a high surface area and a high electrochemical activity space is guaranteed, thereby improving the deposition-dissolution behavior of lithium metal on the current collector and greatly improving the electrochemical performance thereof.
(FR)
Selon la présente invention, l'affinité au lithium de la surface d'un collecteur de courant lui-même est améliorée, et l'utilisation complète d'une surface élevée et d'un espace d'activité électrochimique élevée est garantie, ce qui permet d'améliorer le comportement de dépôt-dissolution du lithium métal sur le collecteur de courant et d'améliorer considérablement sa performance électrochimique.
(ZH)
提高集流体表面本身的亲锂性,保证高的表面和高的电化学活性空间的充分利用,从而改善集流体上金属锂的沉积-溶出行为,大幅提升其电化学性能。
