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.

Molecular Understanding of Li Metal Anode

ECS Meeting Abstracts
Developing new liquid electrolyte is a promising approach to enable the next-generation high-energy Li metal battery for wide-ranging application such as electric vehicles (EV). However, the high reactivity of Li metal interface renders it crucial to form favorable solid-electrolyte interphase (SEI), via active electrolyte decomposition, for highly ...

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].

Designing Current Collectors to Stabilize Li Metal Anodes

Advanced Materials
AbstractRechargeable batteries employing Li metal anodes have gained increasing attention due to their high energy density. Nevertheless, low stability and reversibility of Li metal anodes severely impeded their practical applications. Designing current collectors (CCs) with reasonable structure and composition is an efficient approach to stabilizing ...
