“…The direct-support workflow established in this work enables a high-throughput process for high-resolution single-particle analysis that can be used to obtain statistically relevant data from a number of single particles. In addition, these procedures can assist in the development of a variety of microparticles, including those used in LIBs, zinc-based batteries, 90 and other industrial applications. Future studies will be used to prepare thin cross sections of microscale particles of a variety of compositions; of particular interest is the use of coatings on cathode materials for enhanced durability.…”

The cathode materials in lithium-ion batteries (LIBs) require improvements to address issues such as surface degradation, short-circuiting, and the formation of dendrites. One such method for addressing these issues is using surface coatings. Coatings can be sought to improve the durability of cathode materials, but the characterization of the uniformity and stability of the coating is important to assess the performance and lifetime of these materials. For microscale particles, there are, however, challenges associated with characterizing their surface modifications by transmission electron microscopy (TEM) techniques due to the size of these particles. Often, techniques such as focused ion beam (FIB)-assisted lift-out can be used to prepare thin cross sections to enable TEM analysis, but these techniques are very time-consuming and have a relatively low throughput. The work outlined herein demonstrates a FIB technique with direct support of microscale cathode materials on a TEM grid that increases sample throughput and reduces the processing time by 60–80% (i.e., from >5 to ∼1.5 h). The demonstrated workflow incorporates an air–liquid particle assembly followed by direct particle transfer to a TEM grid, FIB milling, and subsequent TEM analysis, which was illustrated with lithium nickel cobalt aluminum oxide particles and lithium manganese nickel oxide particles. These TEM analyses included mapping the elemental composition of cross sections of the microscale particles using energy-dispersive X-ray spectroscopy. The methods developed in this study can be extended to high-throughput characterization of additional LIB cathode materials (e.g., new compositions, coating, end-of-life studies), as well as to other microparticles and their coatings as prepared for a variety of applications.

“…Graphene materials have good conductivity and are the lowest class of conductive materials among known materials at present. 62 When combined with other materials, it can greatly improve their conductivity. In addition, because Graphene is a single-layer carbon atomic structure, the specific surface area of Graphene is very large, reaching 2600 m 2 g −1 .…”

Zinc ion batteries (ZIBs), as an emerging low-cost and high-safety energy storge option, have the advantages of high energy and low reduction potential. With the development of high-performance cathode materials and electrolyte systems, as well as the deepening of mechanism research, the electrochemical performance of ZIBs has been greatly improved. However, the shortcomings of various materials have hindered the development of zinc ion batteries. With the deepening of research and the deepening of understanding of various materials, a brief outlook was given on the future development of electrode materials in aqueous zinc ion batteries.

“…However, due to the inherent disadvantages of iodine monomers (poor electrical conductivity and thermal stability, high activation energy of iodine conversion), the high solubility of polyiodides in aqueous solution, the dendrite growth of zinc anodes, and the occurrence of side reactions resulting in aqueous zinc-iodide batteries still face many problems, such as the shuttle effect of polyiodide, slow redox kinetics and low energy density. which have impeded their further development [28,29]. Among them, the shuttle effect will not only cause the active material in the cathode to gradually decrease, but also the polyiodide will corrode the anode after reaching the anode, thereby increasing the self-discharge effect inside the battery, reducing the cycle life and Coulombic efficiency, resulting in battery performance deterioration [30,31].…”

Aqueous zinc–iodine batteries are considered to be one of the most promising devices for future electrical energy storage due to their low cost, high safety, high theoretical specific capacity, and multivalent properties. However, the shuttle effect currently faced by zinc–iodine batteries causes the loss of cathode active material and corrosion of the zinc anodes, limiting the large-scale application of zinc–iodine batteries. In this paper, the electrochemical processes of iodine conversion and the zinc anode, as well as the induced mechanism of the shuttle effect, are introduced from the basic configuration of the aqueous zinc–iodine battery. Then, the inhibition strategy of the shuttle effect is summarized from four aspects: the design of cathode materials, electrolyte regulation, the modification of the separator, and anode protection. Finally, the current status of aqueous zinc–iodine batteries is analyzed and recommendations and perspectives are presented. This review is expected to deepen the understanding of aqueous zinc–iodide batteries and is expected to guide the design of high-performance aqueous zinc–iodide batteries.
