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.

Lithium Polysulfide-Based Electrolytes for Li Metal Anodes

ECS Meeting Abstracts, 2020
Li metal batteries (such as lithium–sulfur (Li–S) and lithium-air batteries) have been strongly considered as the promising candidates for the next-generation energy storage devices. Unfortunately, as the result of the notorious Li dendrite growth inherent in these batteries (upon repeated charge/discharge cycling), the concomitant serious safety ...

Nanoconfinement of Metal Hydride-Based Li-Ion Battery Anodes

ECS Meeting Abstracts, 2016
Metal hydrides as anode materials for Li-ion batteries are receiving increased attention due to the high theoretical capacities and low cost of many of these materials. Among conversion-type electrodes, metal hydrides have relatively high energy density and low polarization (ΔV ≈ 0.2 V) [1].
