Double-Edged Effect of Temperature on Lithium Dendrites

ACS Applied Materials & Interfaces, 2020
Lithium metal, although attracting renewed interest for the next revolution in energy storage, continues to be challenged with the detrimental dendrite formation. Recent experimental reports have demonstrated the contrasting impact of thermal attributes on the electrodeposition morphology, showcasing the alleviation and/or aggravation of dendrite ...

Lithium Overpotential and Dendrite Formation

ECS Meeting Abstracts, 2015
Lithium metal has a higher theoretical capacity compared to graphite, which is the most commonly used anode material in a lithium ion battery (LIB).[1] Nevertheless, secondary lithium metal batteries have plenty of challenges to overcome, before they could replace the well established LIBs.

Mechanics of Amorphous Lithium Dendrites

ECS Meeting Abstracts, 2017
The formation of dendrites is a critical drawback for the utilization of Li and other metals in secondary batteries. These emorphous crystals can pierce into the polymer electrolyte and short the cell. Therefore the design/selection criterion requires the dendrite-polymer mechanical compatibility.

A Dendrite‐Free Lithium/Carbon Nanotube Hybrid for Lithium‐Metal Batteries

Advanced Materials, 2020
AbstractLithium (Li) metal is promising in the next‐generation energy storage systems. However, its practical application is still hindered by the poor cycling performance and serious safety issues for the consequence of dendritic Li. Herein, a dendrite‐free Li/carbon nanotube (CNT) hybrid is proposed, which is fabricated by direct coating molten Li on

Strong and brittle lithium dendrites

Science
The growth and penetration of lithium dendrites through electrolytes and separators remain key challenges to realizing high–energy density lithium-metal batteries. Using mechanically strong electrolytes and separators has been considered a promising strategy based on the commonly believed softness of lithium.

Self-heating–induced healing of lithium dendrites

Science, 2018
Healing away the dendrites The formation of lithium dendrites during charge-discharge cycles limits the development of lithium metal batteries, because the dendrites can cause electrical shorting of the cells. A number of tricks have been used to try to prevent dendrite formation. Li et al.

Investigation of Lithium Dendrite Necking and Formation of Dead Lithium Crystals

ECS Meeting Abstracts, 2014
We have investigated the mechanism of formation of dead lithium in manually-fabricated symmetric lithium metal cells. Furthermore, we have characterized the amount of dead lithium based on current intensity and number of cycles and it’s effect on cell impedance.

Understanding and Preventing Dendrite Growth in Lithium Metal Batteries

ACS Applied Materials & Interfaces, 2021
Dendrite growth under large current density is the key intrinsic issue impeding a wider application of Li metal anodes. Previous studies mainly focused on avoiding dendrite growth by building an additional interface layer or surface modification. However, the mechanism and factors affecting dendrite growth for Li metal anodes are still unclear. Herein,

The suppression of lithium dendrite growth in lithium sulfur batteries: A review

Journal of Energy Storage, 2017
Abstract Lithium sulfur batteries (LSBs) are attractive owing to the high theoretical capacities of sulfur cathode active material (1672 mAh g−1) and lithium anode active material (3862 mAh g−1), which leads to a specific energy of approximately 2600 Wh kg−1.
