Stable Li metal anode in a lithiophilic shuttle

Nanoscale, 2022
A lithiophilic shuttle is obtained by the superposition of very thin layered copper oxide flakes, providing conjoined channels for fast and lateral Li+ transfer and stable Li plating/stripping at practical current densities and capacities.

Interfacial challenges towards stable Li metal anode

Nano Energy, 2021
Abstract Rechargeable Li metal batteries once had a glory moment in 1980s, but its development was sooner suspended for safety concerns from dendrite formation. After falling into oblivion for several decades, Li metal anode is reviving in recent years with the ever-growing demands for high energy devices. Despite great progresses have been achieved,

Li Metal Anode with a LiZn Alloy Interlayer for Li-Metal Polymer Batteries

ECS Meeting Abstracts, 2023
All-solid-state batteries (ASSB) require stable and safe Li metal anode, which needs surface preparation to increase lithium diffusion and impede the formation of dendrites. In this work, the formation of a thin LiZn layer on lithium metal using sputter deposition is reported.

Metal oxide anodes for Li-ion batteries

Ionics, 1997
Recently metal oxides, especially tin oxides, have been investigated as negative electrodes in Li-ion batteries. Different compounds such as amorphous SnO2, SnO and SnSiO3 have been electrochemically cycled versus a metallic lithium electrode. In this study, the reversible capacities as well as the cycling behavior of crystalline SnO2 thin films and ...

High Concentrated Electrolytes for Li Metal Anodes

ECS Meeting Abstracts, 2017
Li metal is seen as the ultimate anode for LIBs due to its extremely high theoretical energy density (3860 mAh g-1) and low negative redox potential (-3.04 V vs. standard hydrogen electrode). Making Li metal a ubiquitous anode is the key in propelling energy storage and conversion systems.

Stable Li metal anode with protected interface for high-performance Li metal batteries

Energy Storage Materials, 2018
Abstract Li metal is regarded as the most attractive anode because of its high specific capacity, low reduction potential, and low density. However, low coulombic efficiency and the formation of Li dendrites cause challenges in short cycle life and safety issues, highlighting a need for an innovative design of lithium metal anode with high areal ...

Optimizing Li‐ion Solvation in Gel Polymer Electrolytes to Stabilize Li‐Metal Anode

ChemSusChem, 2023
AbstractGel polymer electrolytes (GPEs) have potential as substitutes for liquid electrolytes in lithium‐metal batteries (LMBs). Their semi‐solid state also makes GPEs suitable for various applications, including wearables and flexible electronics. Here, we report the initiation of ring‐opening polymerization of 1,3‐dioxolane (DOL) by Lewis acid and ...

A Thermally Conductive Separator for Stable Li Metal Anodes

Nano Letters, 2015
Li metal anodes have attracted considerable research interest due to their low redox potential (-3.04 V vs standard hydrogen electrode) and high theoretical gravimetric capacity of 3861 mAh/g. Battery technologies using Li metal anodes have shown much higher energy density than current Li-ion batteries (LIBs) such as Li-O2 and Li-S systems.
