Description
Summary:Lithium (Li) metal, owing to its high specific capacity and low redox potential as a Li + ion source in rechargeable lithium batteries, shows impressive prospects for electrochemical energy storage. However, engineering Li metal into thin foils has historically remained difficult, owing to its stickiness and fragility upon mechanical rolling. Consequently, using thick Li in battery systems betrays the original target for achieving higher energy density, results in material waste, and creates illusions on evaluating modification strategies for taming the highly reactive Li metal anode. Being apprehensive of this, in the tutorial review, we illustrate the argument of applying thin Li (
