Modulating spherical lithium deposition behaviour via guanidine nitrate as an electrolyte additive: enabling dendrite-free lithium metal anodes

Abstract

This study pioneers the use of organic nitrate C(NH₂)₃NO₃ as an electrolyte additive in lithium metal batteries (LMBs). C(NH₂)₃NO₃ can effectively construct a high-quality solid electrolyte interphase (SEI) on the lithium metal anode, thereby enabling dendrite-free and uniform spherical lithium (Li) deposition.
