Linking the Defects to the Formation and Growth of Li Dendrite in All‐Solid‐State Batteries

Advanced Energy Materials, 2021
The nucleation and growth of Li metal during deposition and the associated dendrite penetration are the critical and fundamental issues influencing the safety and power density of solid‐state lithium metal batteries (SSLBs). However, investigations on Li

Liquid Metal Welding to Suppress Li Dendrite by Equalized Heat Distribution

Advanced Functional Materials, 2021
It is important to understand the growth mechanism of Li dendrites for the protection of Li metal anodes. Herein, joule heat as another inducing mechanism for Li dendrites is proposed and demonstrated by experiments and theoretical simulations.

Li-based anode: Is dendrite-free sufficient?

Materials Today, 2020
Abstract Achieving non-dendritic Li deposition is generally believed to be a prerequisite for the successful commercialization of lithium metal batteries (LMBs). However, it is discussed here that eliminating the growth of the dendritic Li structure seems not to be sufficient to propel the LMB technology from laboratory research to practical ...

Ultrathin and Bifunctional Polymer-Nanolayer-Embedded Separator to Simultaneously Alleviate Li Dendrite Growth and Polysulfide Crossover in Li–S Batteries

, 2021
The commercial use of lithium–sulfur (Li–S) batteries is hampered by the shuttle phenomenon in cathodes and the uncontrolled growth of Li dendrites in anodes.

Mathematical Modeling of Multiple-Li-Dendrite Growth in Li-ion Battery Electrodes

Journal of The Electrochemical Society, 2023
Lithium dendrite growth in Li-ion batteries is one of the most dangerous phenomena because it can cause inner short circuits and thermal runaways. However, the nucleation and growth of the dendrites are difficult to predict because of their complex behaviors, which depend on several factors such as the charging conditions and electrode-design ...

Artificial interphases enable dendrite-free Li-metal anodes

Journal of Energy Chemistry, 2021
Abstract Li-metal is an ideal anode that can provide rechargeable batteries with high energy density, but its application in large scale is restricted by its high activity that leads to the severe decomposition of electrolyte components (solvents and salts) and the growth of Li dendrites.

Interfacial Electronic Properties Dictate Li Dendrite Growth in Solid Electrolytes

Chemistry of Materials, 2019
The experimental observation of Li dendrite growth inside mechanically hard solid electrolytes (SEs) raised an important question: can hard SEs mechanically stop Li-dendrite growth?

Dendrite short-circuit and fuse effect on Li/polymer/Li cells

Electrochimica Acta, 2006
We report on experimental and theoretical studies of dendritic growth in Li/polymer/Li symmetric cells. Potential evolution with time, impedance and in situ microscopy experiments enable to characterise the onset and evolution of dendrites. In particular we observe that dendrites may burn when a high enough current goes through them, a thermo-fusible ...

Stable cycling of Li–S batteries by simultaneously suppressing Li-dendrite growth and polysulfide shuttling enabled by a bioinspired separator

, 2020
Lithium–sulfur (Li–S) batteries are very promising candidates for next-generation high-energy-storage devices. However, the uncontrollable Li dendrite growth and notorious polysulfide shuttling severely hinder their real-world applications.

Coregulation of Li/Li⁺ Spatial Distribution by Electric Field Gradient with Homogenized Li‐Ion Flux for Dendrite‐Free Li Metal Anodes

Small, 2023
AbstractLithium (Li) metal batteries are highly sought after for their exceptional energy density. However, their practical implementation is impeded by the formation of dendrites and significant volume fluctuations in Li, which stem from the uneven distribution of Li‐ions and uncontrolled deposition of Li on the current collector.
