Scientists develop functional micro-arrays for efficient lithium metal anode interface

Lithium (Li) metal anodes, with the highest specific capacity (3,860 mAh g-1) and the lowest redox potential (-3.04 V vs. standard hydrogen electrode), are considered a potential alternative for the next generation high-energy-density lithium batteries. However, the unstable electrolyte–Li metal anode interface has been the biggest obstacle for the practical application of Li metal anode batteries.
