Multifunctional Properties of Al2O3/Polyacrylonitrile Composite Coating on Cu to Suppress Dendritic Growth in Anode-Free Li-Metal Battery

, 2020
The utilization of an anode-free lithium-metal battery (AFLMB) is pivotal in meeting the high-energy-density demand for portable electronic devices and vehicles.

Arrayed dendritic growth

Scripta Metallurgica, 1974
Abstract A simple equation is presented to describe the interdendritic spacing for dendritic growth from a super-heated alloy melt. It is then rationalized for a simple conceptual extreme: steady-state unidirectional growth from a liquid under a constant, positive, temperature gradient.

Dendritic Growth Model Involving Interface Kinetics for Supercooled Water.

Langmuir, 2019
The dendritic growth of ice in supercooled water droplets is studied theoretically and experimentally. The measured dendritic growth velocity of ice shows a good agreement with the prediction of the Langer and Müller-Krumbhaar (LM-K) growth model at ...

Steady-state dendritic crystal growth

Physical Review A, 1986
We study the problem of velocity and shape selection in the growth of dendritic crystals. We demonstrate that the presence of surface tension destroys the Ivantsov family of solutions at all but a single velocity. This occurs at all undercoolings and for both two-dimensional and axisymmetric three-dimensional dendrites.

Dendritic growth in a channel

Physical Review A, 1986
We study the growth of dendritic crystals from a supersaturated solution in a channel geometry. This model provides a continuous interpolation between the Saffman-Taylor problem and the (two-dimensional) free-space dendrite. We derive an integral equation for the shape of steady-state propagating fingers, which we treat by discretizing the curve and ...

Impurity effect on dendritic growth

Physical Review A, 1989
We consider the effects of impurities on the velocity selection of a needle crystal, in the small thermal and solutal Peclet numbers. As in the case of the growth in a pure melt, steady solutions for needle crystals are found only if surface tension is anisotropic.

Velocity selection in dendritic growth

Physical Review B, 1986
We show that the velocity and shape of two-dimensional dendritic crystals can be determined by solving the steady-state evolution equation at finite surface tension. We find that in the zero undercooling limit, crystal anisotropy is necessary to obtain finite velocities. Furthermore, the "solvability" condition at zero anisotropy and small undercooling

Dendritic Growth Velocities in Microgravity

Physical Review Letters, 1994
We measured dendritic tip velocities in pure succinonitrile (SCN) in microgravity, using a sequence of telemetered binary images sent to Earth from the space shuttle Columbia (STS-62). Growth velocities were measured as a function of the supercooling over the range 0.05-1.5 K.

Dendritic growth of ZnS crystals

Acta Physica Academiae Scientiarum Hungaricae, 1965
The dendritic growth of ZnS crystals in the form of long ribbons, plates and needles was observed when ZnS crystallized from liquid Ga. The cubic ribbons and plates propagated in the directions, the needles were hexagonal and their main propagation was parallel to the c-axis.
