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.

Triboelectric Nanogenerator-Enabled Dendrite-Free Lithium Metal Batteries

ACS Applied Materials & Interfaces, 2018
Lithium metal batteries (LMBs) are prominent among next-generation energy-storage systems because of their high energy density. Unfortunately, the commercial application of LMBs is hindered by the dendrite growth issue during the charging process. Herein, we report that the triboelectric nanogenerator (TENG)-based pulse output with a novel waveform and

Suppressing Dendritic Lithium Formation Using Porous Media in Lithium Metal-Based Batteries

Nano Letters, 2018
Because of its ultrahigh specific capacity, lithium metal holds great promise for revolutionizing current rechargeable battery technologies. Nevertheless, the unavoidable formation of dendritic Li, as well as the resulting safety hazards and poor cycling stability, have significantly hindered its practical applications.

Dendrite‐Free Lithium Deposition Induced by Uniformly Distributed Lithium Ions for Efficient Lithium Metal Batteries

Advanced Materials, 2016
Li dendrite-free growth is achieved by employing glass fiber with large polar functional groups as the interlayer of Li metal anode and separator to uniformly distribute Li ions. The evenly distributed Li ions render the dendrite-free Li deposits at high rates (10 mA cm(-2)) and high lithiation capacity (2.0 mAh cm(-2)).

Dendritic growth mechanisms in lithium/polymer cells

Journal of Power Sources, 1999
Direct in situ observation of dendritic electrodeposition of lithium has been performed in symmetrical lithium/PEO-LiTFSI cells under galvanostatic conditions. Our experimental set-up allows us to measure simultaneously the variation of the cell potential, the evolution of the dendrites, and the variation of the ionic concentration in the electrolyte ...

Lithium Dendrite Suppression through Controlled Mass Transfer

ECS Meeting Abstracts, 2018
Lithium dendrite formation is a critical challenge that limits the lifetime of lithium (Li) metal batteries including lithium oxygen, and lithium sulfur systems. Dendrite growth occurs at the interface between the electrolyte and the Li metal anode. The formation of dendrites affects the local transport properties, the scale of the critical physics ...

Stabilization Strategies of Lithium Metal Anode Toward Dendrite‐Free Lithium‐Sulfur Batteries

Chemistry – A European Journal
AbstractLithium‐sulfur (Li−S) batteries are considered as a most promising rechargeable lithium metal batteries because of their high energy density and low cost. However, the Li−S batteries mainly suffer the capacity decay issue caused by the shutting effect of lithium polysulfides and the safety issues arising from the Li dendrites formation.

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
