Liquid Metal Coating for Improving Li-Anode Cyclability

ECS Meeting Abstracts, 2020
Lithium metal is a promising anode material for Li-ion batteries because of its high specific capacity and negative electrochemical potential. However, there are two major challenges that need to be overcome before it can be used in practical applications: 1) electrolyte consumption and 2) dendrite.

Towards better Li metal anodes: Challenges and strategies

Materials Today, 2020
Abstract Anode materials are key components of batteries that significantly impact their specific energy and power. Li metal is considered as the ultimate anode due to its high theoretical capacity (∼3860 mA h/g) and low redox potential (−3.04 V vs. standard hydrogen electrode). Specifically, rechargeable Li metal batteries (LMBs) with enabled safety

Nitrogen‐Doped Anodic Li Oxide Films as Robust Li Metal Anodes and Solid‐State Electrolytes

Advanced Energy Materials
AbstractThe performance of the lithium (Li) metal anode in rechargeable batteries has been hampered by the formation of unstable solid‐electrolyte interphase layers, which compromise cycle life and pose significant safety concerns. Herein, for the first time, the anodizing oxidation of pure Li in a liquid electrolyte is developed by using ...

Advanced Current Collectors Towards Stable Li Metal Anode

ECS Meeting Abstracts, 2018
Metallic lithium (Li) is a promising anode material for next generation rechargeable batteries. However, the dendrite growth of Li and repeated formation of solid electrolyte interface (SEI) during Li plating and stripping result in low Coulombic efficiency, internal short circuit, and capacity decay, hampering its practical application.
