Title (EN) PULSE CHARGING METHOD FOR LITHIUM METAL BATTERY
(FR) PROCÉDÉ DE CHARGE PAR IMPULSIONS POUR BATTERIE AU LITHIUM MÉTALLIQUE
(ZH) 一种应用于锂金属电池的脉冲充电方法
Abstract:
(EN) Disclosed is a pulse charging method for a lithium metal battery, wherein the pulse charging method involves pulsed current charging; and the electrode material of the lithium metal battery is selected from pure lithium metal, lithium metal alloy or lithium metal-carbon materials. The present invention provides a pulse charging mode for a lithium metal battery, which mode can inhibit the growth of a lithium dendrite and reduce volume expansion, thereby having the effects of effectively protecting a lithium metal electrode, prolonging the service life, stabilizing circulation and improving safety.
(FR) L'invention concerne un procédé de charge par impulsions pour batterie au lithium métallique, le procédé de charge par impulsions implique une charge à courant pulsé ; et le matériau d'électrode de la batterie au lithium métallique est choisi parmi du lithium métallique pur, un alliage de lithium métallique ou des matériaux à base de lithium métal-carbone. La présente invention concerne un mode de charge par impulsions pour batterie au lithium métallique, ledit mode peut inhiber la croissance de dendrites de lithium et réduire l'expansion du volume, ce qui a pour effet de protéger efficacement une électrode au lithium métallique, de prolonger la durée de vie, de stabiliser la circulation et d'améliorer la sécurité.
(ZH) 本发明公开了一种应用于锂金属电池的脉冲充电方法,所述脉冲充电方法为脉冲电流充电;所述锂金属电池的电极材料选自纯锂金属、锂金属合金或锂金属-碳材料。本发明提供了一种应用于锂金属电池的脉冲充电方式,可以实现抑制锂枝晶生长,减少体积膨胀,从而起到有效保护锂金属电极,延长使用寿命,稳定循环,提高安全性的作用。
