Realizing Dendrite-Free Lithium Deposition with a Composite Separator

open access: yesNano Letters, 2020
A dendrite-free Li deposition strategy is developed with a composite separator of MnCO3 coated porous polypropylene. Mn2+ ions are preferentially reduced to form Mn nanoparticles on Li anodes, which helped to reduce the nucleation overpotential and achieve a dendrite-free deposition of Li bulky grains.

Dendrite-Free Lithium Deposition with Self-Aligned Nanorod Structure

Nano Letters, 2014
Suppressing lithium (Li) dendrite growth is one of the most critical challenges for the development of Li metal batteries. Here, we report for the first time the growth of dendrite-free lithium films with a self-aligned and highly compacted nanorod structure when the film was deposited in the electrolyte consisting of 1.0 M LiPF6 in propylene carbonate

Amine-Wetting-Enabled Dendrite-Free Potassium Metal Anode

ACS Nano, 2022
Considered as an imperative alternative to the commercial LiFePO4 battery, the potassium metal battery possesses great potential in grid-scale energy storage systems due to the low cost, low standard redox potential, and high abundance of potassium. The potassium dendrite growth, large volume change, and unstable solid electrolyte interphase (SEI) on ...

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 ...

Triboelectric Nanogenerator-Enabled Dendrite-Free Lithium Metal Batteries

ACS Applied Materials & Interfaces, 2018
Lithium metal batteries (LMBs) are prominent among next-generation energy-storage systems because of their high energy density. Unfortunately, the commercial application of LMBs is hindered by the dendrite growth issue during the charging process. Herein, we report that the triboelectric nanogenerator (TENG)-based pulse output with a novel waveform and

Adjustable Mixed Conductive Interphase for Dendrite-Free Lithium Metal Batteries

ACS Nano, 2022
Lithium (Li) metal batteries with high energy density are of great promise for next-generation energy storage; however, they suffer from severe Li dendritic growth and an unstable solid electrolyte interphase. In this study, a mixed ionic and electronic conductive (MIEC) interphase layer with an adjustable ratio assembled by ZnO and Zn nanoparticles is
