Mathematical Modeling of Multiple-Li-Dendrite Growth in Li-ion Battery Electrodes
Journal of The Electrochemical Society, 2023Lithium 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 ...

Li dendrite growth and Li+ ionic mass transfer phenomenon
Journal of Electroanalytical Chemistry, 2011Abstract Li metal dendrite growth in LiPF6–propylene carbonate (PC) electrolyte was observed in situ by a laser scanning confocal microscope (LSCM) with a metallographic microscope. The development of the electrodeposited Li dendrite length was analyzed, and compared with dendrites grown in LiClO4–PC electrolyte solution.

Li-based anode: Is dendrite-free sufficient?
Materials Today, 2020Abstract 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 ...

The Bonding Nature and Adhesion of Polyacrylic Acid Coating on Li-Metal for Li Dendrite Prevention
ACS Applied Materials & Interfaces, 2020The success of polyacrylic acid (PAA) to suppress Li dendrite growth suggests that the mechanical properties of polymer-based coatings, including the modulus, toughness, and interfacial adhesion are important design criteria. However, the measurement of the adhesion of thin PAA, as well as other polymer coatings to the reactive Li-metal anode surface ...

Dendrite short-circuit and fuse effect on Li/polymer/Li cells
Electrochimica Acta, 2006We 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 ...

Quantitative Phase Field Modeling of Li Dendrite Growth
ECS Meeting Abstracts, 2022Modeling and understanding dendrite growth on lithium metal anodes during charging is vital for improving battery safety. The phase field method has become an increasingly popular tool to achieve this due to its flexibility in handling complex morphologies and coupled physical processes.

A dendrite-free Li plating host towards high utilization of Li metal anode in Li–O2 battery
Science Bulletin, 2019The intense interest of Li-O2 battery stems from its ultrahigh theoretical energy density, but its application is still hindered by the issues of Li anode. Herein, RuO2-CNTs composite, a conventional O2 cathode catalyst in Li-O2 battery, is first utilized as an anode host for dendrite-free Li plating/stripping with high Coulombic efficiency.

Electrochemical Polishing: An Effective Strategy for Eliminating Li Dendrites
Advanced Functional Materials, 2022AbstractDendritic growth of lithium (Li) is well‐known to originate from deposition on rough and inhomogeneous Li‐metal surfaces, and has long been a central problem in charging lithium metal batteries. Herein, a universal strategy is proposed for dendrite suppression by both in situ and ex situ electrochemical polishing of Li metal from the corrosion ...
