Implementation of Anode-Free Concept in Sulfide-Based All-Solid-State Batteries

Beschreibung

Driven by the increasing demand for electric vehicles, lithium-ion battery research has shifted toward all-solid-state systems due to their higher energy density and compatibility with lithium metal. An anode-free battery concept has been proposed to further enhance energy density and safety by replacing lithium metal with a thin anode buff er layer. This dissertation builds on a silver–carbon composite buff er layer developed by Samsung and investigates how modifi cations in anode composition and structure infl uence battery performance. Different conductive carbons, lithiophilic metals, and dual-layer anode designs were explored, with processing methods optimized accordingly. The anodes were evaluated in single-layer pouch cells using solid sulfi de electrolytes, followed by post-mortem analyses tostudy lithium deposition and degradation mechanisms. The results provide practical insights into implementing anode-free solid-state batteries.
