Lithium metal anode is a promising candidate anode in lithium‐sulfurized polyacrylonitrile (SPAN) batteries. Nevertheless, the formation of lithium dendrites is recognized as the worst problem for lithium metal batteries. Herein, a hybrid solid interphase is synthesized on lithium with a facile method. This modified lithium anode can not only suppress lithium dendrites, but also gives rise to a fast interfacial transport mechanism. When used in a lithium‐SPAN battery, a reversible capacity of 450 mAh g⁻¹ (based on SPAN) is delivered at 10 A g⁻¹, which is a promising candidate for high specific power batteries.

增强锂硫化聚丙烯腈电池中锂金属阳极界面的快速离子传输

锂金属阳极是锂硫化聚丙烯腈（SPAN）电池中有希望的候选阳极。然而，锂枝晶的形成被认为是锂金属电池最严重的问题。在此，通过简便的方法在锂上合成杂化固相。这种改性的锂阳极不仅可以抑制锂枝晶，还可以产生快速的界面传输机理。当用于SPAN锂电池时，可在10 A g ^-1下提供450 mAh g ^-1（基于SPAN）的可逆容量，这是高比功率电池的有希望的候选者。
