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 ...

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.

Nanostructured Li Metal Anode to Inhibit Dendrite Growth in Safe Li-Metal Batteries
ECS Meeting Abstracts, 2016Li metal is considered as the “Holy Grail” of energy storage systems due to its extremely high theoretical specific capacity (3860 mAh g−1), low gravimetric density (0.59 g cm−3), and lowest negative redox potential (−3.040 V vs. standard hydrogen electrode).

The inhibited Li dendrite growth via bulk/liquid dual-phase modulation
Journal of Colloid and Interface Science, 2023Li metal is a potential anode material for the next generation high-energy-density batteries because of its high theoretical specific capacity. However, the inhomogeneous lithium dendrite growth restrains corresponding electrochemical performance and brings safety concerns.

Abstract Lithium dendrite growth in Li/poly(ethylene oxide) (PEO)–Li(CF 3 SO 2 ) 2 N (LiTFSI)–nano-SiO 2 /Li was examined using direct in situ observation under galvanostatic conditions at 60 °C. Both the onset time of dendrite formation and the short-circuit time of the cells were extended by the addition of nano-SiO 2 filler into the polymer ...

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 ...

Prospects for Dendrite-Free Cycling of Li Metal Batteries
Journal of The Electrochemical Society, 2015We discuss the general origins of three-dimensional (3D) growth and morphology instability that can occur during homoepitaxial electrodeposition on initially planar single crystal surfaces and then focus on specific issues relevant to polycrystalline Li metal electrode dissolution/deposition cycling.
