An Organic Electrolyte Additive for the Suppression of Li Dendrite in Li Metal Based Batteries
ECS Meeting Abstracts, 2018Li metal has been known as an ideal anode material for high performance batteries due to its high theoretical specific capacity and lowest working potential. However, Li metal is thermodynamically unstable in polar aprotic electrolytes: it reacts with the electrolytes to form a solid electrolyte interface (SEI) layer.

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.

In Situ Observation of Dendrite Growth of Electrodeposited Li Metal
Journal of The Electrochemical Society, 2010The dendrite growth behavior of Li metal galvanostatically electrodeposited on Ni substrate in a LiClO 4 -propylene carbonate electrolyte solution was in situ observed by a laser scanning confocal microscope with a metallographic microscope. A Li dendrite precursor is stochastically evolved on Ni substrate probably through a solid electrolyte ...

Drift Effect of Li Ions in Electrolytes on Dendritic Morphology
ECS Meeting Abstracts, 2015In Li-metal and Li-air batteries, anodic materials are Li metals. In contrast to the intercalation materials such as the graphite, however, the morphology of the Li metal anode surface is not uniform, i.e., dendritic growth, during battery charging. In this study, dendritic growth was simulated by using the diffusion-limited aggregation (DLA) model ...

Effect of Li-Mg Alloy Anode on Li Dendrite Suppressionfor Li-Air Secondary Batteries
ECS Meeting AbstractsNon aqueous Li-air battery (LAB) has been attracting much attention as one of the next-generation batteries because it has a theoretical capacity about ten times that of the conventional Li-ion battery (3505 Wh kg-1). However, there is a risk of short-circuit due to Li dendrite formation on the surface of Li metal anode by charge/discharge cycling ...

The Bonding Nature and Adhesion of Li and Polyacrylic Acid (PAA) Coating for Li Dendrite Prevention
ECS Meeting Abstracts, 2020Vehicle electrification requires lithium ion batteries (LIB) with higher energy density to make possible the extended driving range at a lower cost. One promising approach is to adopt the lithium metal as the anode due to its ultrahigh capacity and lowest reduction potential; however, Li dendrite growth is an inevitable bottleneck that can lead to ...

The Influence of Solid Electrolyte Interface (SEI) on Li Dendrites Formation in Li-Metal Battery
ECS Meeting Abstracts, 2020The composition, structure and the formation mechanism of the solid-electrolyte interphase (SEI) in lithium-based (e.g., Li-ion and Li-metal) batteries have been widely explored in the literature. However, very little is known about the ions transport through the SEI, specifically through their grain boundaries (GBs) of the inorganic inner layers ...

Understanding and Predicting Li Dendrite Formation in Li-Ion Batteries: Phase Field Model
ECS Meeting Abstracts, 2014Lithium dendrite formation can lead the degradation and failure of Lithium ion battery, either because dendrite pieces lose electrical contract with the rest of the Li electrode (typically during Li stripping on discharge) or because growing dendrite can penetrate the separator and lead to internal short-circuiting.

Redistributing Li‐Ion Flux by Parallelly Aligned Holey Nanosheets for Dendrite‐Free Li Metal Anodes
Advanced Materials, 2020AbstractLi metal is the most ideal anode material to assemble rechargeable batteries with high energy density. However, nonuniform Li‐ion flux during repeated Li plating and stripping leads to continuous Li dendrite growth and dead Li formation, which causes safety risks and short lifetime and thus impedes the commercialization of Li metal batteries ...
