The synergetic effect of lithium polysulfide and lithium nitrate to prevent lithium dendrite growth [PDF]

Nature Communications, 2015
Lithium metal has shown great promise as an anode material for high-energy storage systems, owing to its high theoretical specific capacity and low negative electrochemical potential. Unfortunately, uncontrolled dendritic and mossy lithium growth, as well as electrolyte decomposition inherent in lithium metal-based batteries, cause safety issues and ...

Lithium dendrite suppression and cycling efficiency of lithium anode

Electrochemistry Communications, 2018
Abstract We propose a novel binary electrolyte of lithium bis(fluorosulfonyl)imide/1,3-dioxolane, that exhibits excellent performance for the suppression of lithium-dendrite growth and stability against lithium metal. With 2.5 M lithium bis(fluorosulfonyl)imide in 1,3-dioxolane, long short-circuit onset-times of 72.3 and > 190 h are observed in Li/Li

Coatings on Lithium Battery Separators: A Strategy to Inhibit Lithium Dendrites Growth

Molecules, 2023
Lithium metal is considered a promising anode material for lithium secondary batteries by virtue of its ultra-high theoretical specific capacity, low redox potential, and low density, while the application of lithium is still challenging due to its high activity.

Dynamics of Lithium Dendrite Growth and Inhibition: Pulse Charging Experiments and Monte Carlo Calculations [PDF]

, 2014
Short-circuiting via dendrites compromises the reliability of Li-metal batteries. Dendrites ensue from instabilities inherent to electrodeposition that should be amenable to dynamic control.

Quantifying Inactive Lithium in Lithium Metal Batteries [PDF]

, 2019
Inactive lithium (Li) formation is the immediate cause of capacity loss and catastrophic failure of Li metal batteries. However, the chemical component and the atomic level structure of inactive Li have rarely been studied due to the lack of effective ...

Lithium Difluorophosphate as a Dendrite-Suppressing Additive for Lithium Metal Batteries

ACS Applied Materials & Interfaces, 2018
The notorious lithium (Li) dendrites and the low Coulombic efficiency (CE) of Li anode are two major obstacles to the practical utilization of Li metal batteries (LMBs). Introducing a dendrite-suppressing additive into nonaqueous electrolytes is one of the facile and effective solutions to promote the commercialization of LMBs.

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

Advanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition
