“…Thanks to the unique properties of Sn as a metal related to its high electrical conductivity, low electrochemical migration behavior, excellent solderability and low material cost, Sn in the form of powder found wide application in many industries [1]. The most important industries using Sn powder are: powder metallurgy, lithium-ion battery production, electronic industry and manufacture of tin solder paste [2]. Sn powders are also widely used in optoelectronics, production of specialized alloys with copper (bronze), niobium (Nb 3 Sn) and zirconium, in production of food packaging for distilled water, beer and carbonated drinks, storage tanks for pharmaceutical chemical solutions, in capacitors electrodes, fuse-wires, ammunitions, tinned iron sheets to protect victuals, sweets, or tobacco, etc.…”

The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolyte has been investigated. Morphology and structure of Sn dendrites produced applying both potentiostatic and galvanostatic regimes of the electrolysis are characterized by SEM and XRD, respectively. Depending on the applied cathodic potentials, three types of Sn dendrites were obtained: (a) needle-like and spear-like, (b) fern-like, and (c) stem-like dendrites. The very branchy dendrites with branches of the prismatic shape obtained by the galvanostatic regime of electrolysis represented a novel type of Sn dendrites, not previously reported in the literature. To explain the formation of various dendritic forms, correlation with the polarization characteristics for this electrodeposition system is considered. The needle-like and the spear-like dendrites represented monocrystals of (200),(400) preferred orientation, the fern-like dendrites exhibited the predominant (220),(440) preferred orientation, while in the stem-like particles Sn crystallites were oriented to a greater extent in the (440) crystal plane than in other planes. The galvanostatically synthesized Sn particles possessed the strong (200),(400) preferred orientation. The strong influence of parameters and regimes of electrodeposition on structural characteristics of Sn dendrites is explained by the fundamental laws of electrocrystallization taking into consideration the concept of slow-growing and fast-growing crystal planes.

“…Aside from the 3D dendrites, the mixture of the needle-like and the 2D dendrites was also formed at the high current density. Simultaneously, the calculated TC(hkl) coefficients showed that this change of the particle morphology was accompanied by the change of the preferred orientation of the particles from (200) to (101) [61]. With an increase in the concentration of Sn(II) ions, the morphology of the powders changed from the needle-like and the 3D dendrites with well-defined stalk and branches to the particles with pyramid chain structure, the needle-like and the 3D dendrites, and those like coarse pyramids.…”

At the high Sn(II) concentration, the strong (200) preferred orientation is observed, whereas at the low Sn(II) concentration, Sn crystallites were dominantly oriented in the (211) plane [61]. Temperature also had a strong effect on the shape of Sn powder particles electrolytically obtained in ChCl-EG DES.…”

“…All mechanisms explaining the formation of Pb powder particles from the aqueous solutions are also valid for the formation of Pb powders from this electrolyte type. Tin (Sn) powder particles with pyramid chain and dendritic structures were dominantly obtained by electrolysis in choline chloride-ethylene glycol deep eutectic solvent (ChCl-EG DES) [61,62]. The morphology of the particles changed from irregular particles to both long straight pyramid chains and 3D dendrites with increasing current density.…”

In this review paper, morphologies of metal powders produced by the constant (potentiostatic and galvanostatic) regimes of electrolysis from aqueous electrolytes are correlated with their crystal structure at the semiquantitative level. The main parameters affecting the shape of powder particles are the exchange current density (rate of electrochemical process) and overpotential for hydrogen evolution reaction. Depending on them, various shapes of dendrites (the needles, the two-dimensional (2D) fern-like, and the three-dimensional (3D) pine-like dendrites), and the particles formed under vigorous hydrogen evolution (cauliflower-like and spongy-like particles) are produced by these regimes of electrolysis. By decreasing the exchange current density value, the crystal structure of the powder particles is changed from the strong (111) preferred orientation obtained for the needle-like (silver) and the 2D (lead) dendrites to the randomly orientated crystallites in particles with the spherical morphology (the 3D dendrites and the cauliflower-like and the spongy-like particles). The formation of metal powders by molten salt electrolysis and by electrolysis in deep eutectic solvents (DESs) and the crystallographic aspects of dendritic growth are also mentioned in this review.

Exploiting the ability to directly deposit larger‐sized, flexible, alloying‐type sodium‐ion battery electrodes without the need of additional inactive components and processing steps is a strategic way to achieve higher gravimetric capacities which will be suitable for commercial‐level sodium‐ion (SIB) pouch cell manufacturing. In this regard, a simple, template‐free electroplating protocol is reported for designing phase‐pure tin antimonide (TA)‐based negatrode. An optimum control over the potentiostatic electroplating parameters allows the preferential formation of dendritic nanostructures over an electroplated foam‐based current collector. The prepared negatrode and Mn‐based Prussian blue analog positrode in full coin cell format deliver an average nominal working voltage of 3.0 V with a discharge energy density of 342 Wh kg−1. In single‐layer full pouch cell format, an 8.01 mAh capacity (89.89 mAh g−1, 593.3 µAh cm−2) is achieved at an undeformed state and 97.12% capacity is retained at 180° bend condition. In multi‐layer full pouch cell format, a 35.86 mAh capacity (80.58 mAh g−1, 531.2 µAh cm−2) is achieved with 62.77% capacity retention after 200 cycles (0.125 C). The results of this work showcase how a simple, template free, aqueous electrolyte based electroplating protocol can be developed for the direct fabrication of large‐sized, flexible, alloying‐type negatrodes for commercial SIB pouch cells.
