Dendrite‐Free Li‐Metal Anode Enabled by Dendritic Structure

Advanced Functional Materials, 2021
AbstractThe practical application of Li‐metal anode in high‐energy rechargeable Li batteries is still hindered by the uncontrollable formation of Li dendrites. Here, a facile way is reported to stabilize Li‐metal anode by building dendrite‐like Li3Mg7 alloys enriched with Li‐containing polymers as the physical protecting layer and LiH as the Li‐ion ...

How Does External Pressure Shape Li Dendrites in Li Metal Batteries?

Advanced Energy Materials, 2021
AbstractHigh‐energy density lithium metal batteries have achieved great progress as next‐generation rechargeable cells. However, the huge gap in the switching from coin to pouch cells hinders their practical application. External pressure, as one discrepancy between coin and pouch cells, plays an important role in the performance of Li metal anodes ...

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 ...

Li dendrite growth and Li+ ionic mass transfer phenomenon

Journal of Electroanalytical Chemistry, 2011
Abstract 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.

Mathematical Modeling of Multiple-Li-Dendrite Growth in Li-ion Battery Electrodes

Journal of The Electrochemical Society, 2023
Lithium 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 ...

Artificial interphases enable dendrite-free Li-metal anodes

Journal of Energy Chemistry, 2021
Abstract Li-metal is an ideal anode that can provide rechargeable batteries with high energy density, but its application in large scale is restricted by its high activity that leads to the severe decomposition of electrolyte components (solvents and salts) and the growth of Li dendrites.

Dendrite short-circuit and fuse effect on Li/polymer/Li cells

Electrochimica Acta, 2006
We 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 ...
