Lithium Overpotential and Dendrite Formation
ECS Meeting Abstracts, 2015Lithium 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, 2017The 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, 2020AbstractLithium (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

Investigation of Lithium Dendrite Necking and Formation of Dead Lithium Crystals
ECS Meeting Abstracts, 2014We 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, 2021Dendrite 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, 2017Abstract 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.

Surface dendrite in lithium niobate crystals
Materials Research Bulletin, 1973Abstract The growth of a surface dendrite of a complex nature has been observed in lithium niobate grown perpendicular to the c-axis. The dendrite limbs in different directions are described and a growth mechanism is suggested. It was found that a small volume of the melt in the crucible and a rapid rate of cooling do not favour the dendritic growth.

Characterization and Modeling of Lithium Dendrite Growth
2016The Li dendrite growth and corrosion of Li anode during the Li deposition process are critical issues for the battery safety and long term cyclability of Li metal batteries. In this chapter, we will first review various instruments/tools that are critical for the characterization of Li dendrite growth/stripping processes and analysis on the composition

Realizing Dendrite-Free Lithium Deposition with a Composite Separator
Nano Letters, 2020A dendrite-free Li deposition strategy is developed with a composite separator of MnCO3 coated porous polypropylene. Mn2+ ions are preferentially reduced to form Mn nanoparticles on Li anodes, which helped to reduce the nucleation overpotential and achieve a dendrite-free deposition of Li bulky grains.
