Carbon materials for stable Li metal anodes

2021
Lithium (Li) metal is regarded as the ultimate anode for next-generation Li-ion batteries due to its highest specific capacity and lowest electrochemical potential. However, the Li metal anode has limitations, including virtually infinite volume change, nonuniform Li deposition, and an unstable electrode-electrolyte interface, which lead to rapid ...

Nanopile Interlocking Separator Coating toward Uniform Li Deposition of the Li Metal Anodes

ACS Applied Materials & Interfaces, 2020
Uncontrollable growth of lithium (Li) dendrite has severely hindered the development of Li metal anodes, while separator modification is regarded as a simple and effective way to mitigate the growth of Li dendrite. However, the "drop-dregs" phenomenon of coating layer desquamated from polyolefin separator due to their different Young's modulus would ...

Self-Assembled Conductive Metal-Oxide Nanofiber Interface for Stable Li-Metal Anode

ACS Applied Materials & Interfaces, 2019
Li-metal anodes promise to build high-energy-storage systems, but they suffer from safety problems from severe dendrite growth. Here, we develop a thin and conformal hybrid ionic and electronic conducting metal-oxide nanofiber interface to stabilize Li-anodes without forming dendrites. The thin ionic-conductive Li0.33La0.56TiO3 (LLTO) nanofiber film is

Enhancing Performance of Anode-Free Li-Metal Batteries

ECS Meeting Abstracts, 2023
Because of their higher energy density, compared to lithium-ion batteries, rechargeable lithium-metal batteries (LMB) have been considered one of the most attractive next-generation energy-storage systems (ESS). A promising approach to improving LMB performance, that has gained interest in recent years ...

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 ...
