Battery Brew 47|减缓锌电沉积动力学既能优化也能破坏稳定性

from EKL Battery Brew

播客概述:欢迎收听本期节目!关键内容提要:传统观点认为“越慢越好”(降低交换电流密度)可抑制枝晶;但文献普遍存在“最佳添加剂浓度”,过量后性能断崖式下降。提出“双路径竞争模型”——电子在锌沉积(正道)和析氢/腐蚀(邪道)间竞争。适度减缓沉积动力学 → 均匀致密锌层(优异(002)晶面)→ 抑制副反应;过度减缓 → 电荷转移电阻过高 → 电子被迫涌向副反应 → 严重析氢、腐蚀、电池崩溃。Reference: Slowing Down Zinc Electrodeposition Kinetics Can Maximize and Compromise Anode Stability: How Slow Is Too Slow?感谢收听!继续充电,也继续酿造好生活!#EKLBatteryBrew更多电池前沿论文&解读,探索X账号:@[EKL_Batteries](x.com)前往小宇宙评论区与主播互动
