Abstract
Herein a spontaneously formed solid electrolyte interface (SEI) layer with modified spherical structure is prepared by a simple strategy. Caprolactone (CL) is in-situ polymerized to polycaprolactone (PCL) after being triggered by Li metal, and turned into spherical distribution at the surface of Li after recrystallization treatment. Spontaneously formed spherical structure restrains the growth of Li dendrites and boosts homogeneous Li deposition. The Li||Li symmetrical cells present stable plating/stripping behavior at current density of 0.5 to 1.0 mA cm−2 and exhibit excellent cycling stability. This work provides inspiration for restraining the growth of Li dendrites and building stable electrolyte/metal anode interfaces.
期刊介绍：
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
