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.

The Bonding Nature and Adhesion of Polyacrylic Acid Coating on Li-Metal for Li Dendrite Prevention

ACS Applied Materials & Interfaces, 2020
The 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 ...

Effect of nano-silica filler in polymer electrolyte on Li dendrite formation in Li/poly(ethylene oxide)–Li(CF3SO2)2N/Li

Journal of Power Sources, 2010
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 ...

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 ...
