Lithium metal anodes potentially offer an ultrahigh energy density for Li‐ion batteries. In article number 1701482, Nae‐Lih Wu and co‐workers report a new strategy for developing a dendrite‐free Li anode technology. A high‐polarity β‐phase poly(vinylidene difluoride) thin coating with an electronegative F‐rich interface on either copper or lithium metal substrates is demonstrated to enable uniform massive lithium deposition/stripping and high cycle stability.

阳极：用于无枝晶和高性能锂金属阳极的高极性聚偏二氟乙烯薄涂层（Adv。Energy Mater。2/2018）

锂金属阳极可能为锂离子电池提供超高的能量密度。Nae-Lih Wu及其同事在文章编号1701482中报告了开发无枝晶锂阳极技术的新策略。事实证明，在铜或锂金属基材上具有高负电F界面的高极性β相聚偏二氟乙烯薄涂层可以实现均匀的块状锂沉积/剥离和高循环稳定性。
