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.

A dendrite-free Li plating host towards high utilization of Li metal anode in Li–O2 battery

Science Bulletin, 2019
The 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.

Redistributing Li‐Ion Flux by Parallelly Aligned Holey Nanosheets for Dendrite‐Free Li Metal Anodes

Advanced Materials, 2020
AbstractLi 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 ...

Electrochemical Polishing: An Effective Strategy for Eliminating Li Dendrites

Advanced Functional Materials, 2022
AbstractDendritic 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 ...

Computation-accelerated Design of Dendrite-free Li Batteries

2023
The main obstacle to the development of the next-generation Li-based batteries is the formation of Li dendrite on the anode surface. Li dendrite growth contributes to the reduction of coulombic efficiency, poor cycling performance, and internal short circuits.
