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.

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.

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.

Surface dendrite in lithium niobate crystals

Materials Research Bulletin, 1973
Abstract 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.

Bulk Properties of Amorphous Lithium Dendrites

ECS Transactions, 2017
The formation of dendrites is a critical drawback for the utilization of lithium in secondary batteries. These amorphous crystals can pierce into the polymer electrolyte and short the cell. Therefore the design/selection criterion requires the mechanical compatibility of the grown dendrites from electrode and the solid polymer electrolyte.

Characterization and Modeling of Lithium Dendrite Growth

2016
The 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

Solid‐State Electrolyte Design for Lithium Dendrite Suppression

Advanced Materials, 2020
AbstractAll‐solid‐state Li metal batteries have attracted extensive attention due to their high safety and high energy density. However, Li dendrite growth in solid‐state electrolytes (SSEs) still hinders their application. Current efforts mainly aim to reduce the interfacial resistance, neglecting the intrinsic dendrite‐suppression capability of SSEs.

Interlayered Dendrite‐Free Lithium Plating for High‐Performance Lithium‐Metal Batteries

Advanced Materials, 2019
AbstractFor its high theoretical capacity and low redox potential, Li metal is considered to be one of the most promising anode materials for next‐generation batteries. However, practical application of a Li‐metal anode is impeded by Li dendrites, which are generated during the cycling of Li plating/stripping, leading to safety issues.
