“…inverse structures) because inverse structures have larger pores, better pore interconnectivity, and improved mechanical stability. Using block copolymers to make mesoporous materials, 429,430 the surface area can be further increased. Charge transport generally occurs across 1-10 nm, so the structure on the 100-nm scale does not matter; however, ordered structures ensure that the pores are fully interconnected for ion diffusion.…”

“…One of the primary reasons hierarchical CBPM are used as electrodes is their high surface area, with a higher active area for a given volume of material. High surface area allows for easy access to active materials in batteries 75,421,423,426,[428][429][430][431] and fuel cells, 432,433 improving energy density. It also leads to higher dye loading, and thus increased light absorption and higher rates, in dye-sensitized solar cells.…”

“…341,458 Much like for catalysis, the macroporous structure of CBPM provides for easier diffusion to the active surface; in electrodes, fast ion diffusion means faster charging and reaction rates. 430 Ordered, inverse structures have been particularly well investigated as a means of controlling ion transport, for example in Li-ion batteries, 26,428,466 Li-air batteries, 431 dye-sensitized solar cells (DSSC), 450 and fuel cells. 432,433 These colloid-templated structures have also been used as separators in batteries 184 and fuel cells 434 due to their ability to control ion diffusion.…”

Nature evolved a variety of hierarchical structures that produce sophisticated functions. Inspired by these natural materials, colloidal self-assembly provides a convenient way to produce structures from simple building blocks with a variety of complex functions beyond those found in nature. In particular, colloid-based porous materials (CBPM) can be made from a wide variety of materials. The internal structure of CBPM also has several key attributes, namely porosity on a sub-micrometer length scale, interconnectivity of these pores, and a controllable degree of order. The combination of structure and composition allow CBPM to attain properties important for modern applications such as photonic inks, colorimetric sensors, self-cleaning surfaces, water purification systems, or batteries. This review summarizes recent developments in the field of CBPM, including principles for their design, fabrication, and applications, with a particular focus on structural features and materials' properties that enable these applications. We begin with a short introduction to the wide variety of patterns that can be generated by colloidal self-assembly and templating processes. We then discuss different applications of such structures, focusing on optics, wetting, sensing, catalysis, and electrodes. Different fields of applications require different properties, yet the modularity of the assembly process of CBPM provides a high degree of tunability and tailorability in composition and structure. We examine the significance of properties such as structure, composition, and degree of order on the materials' functions and use, as well as trends in and future directions for the development of CBPM.

“…The conventional structure of lithium ion battery mainly consists of cathode, electrolyte, separator, anode, gasket, gas release value, and sealing plate shown in Fig. 1 [8]. The cathode is the positive electrode of the battery, which means it is the source of positive ions (Li + ) and accepts negative ions (e − ).…”

“…The cathode is the positive electrode of the battery, which means it is the source of positive ions (Li + ) and accepts negative ions (e − ). In layered cathodes, the composition is denoted by LiMO 2 , where M corresponds to Co, Ni, Mn or V [8]. LiCoO 2 is currently the most popular option, despite the high cost of cobalt, as it is relatively easy to prepare an electrode with a layered structure of extremely high quality.…”

ODZYSK PROSZKU ELEKTRODOWEGO Z ZUŻYTYCH AKUMULATORÓW LITOWO-JONOWYCHThis study was focused on recycling process newly proposed to recover electrodic powder enriched in cobalt (Co) and lithium (Li) from spent lithium ion battery. In addition, this new process was designed to prevent explosion of batteries during thermal treatment under inert atmosphere. Spent lithium ion batteries (LIBs) were heated over the range of 300 • C to 600 • C for 2 hours and each component was completely separated inside reactor after experiment. Electrodic powder was successfully recovered from bulk components containing several pieces of metals through sieving operation. The electrodic powder obtained was examined by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), and atomic absorption spectroscopy (AA) and furthermore image of the powder was taken by scanning electron microscopy (SEM). It was finally found that cobalt and lithium were mainly recovered to about 49 wt.% and 4 wt.% in electrodic powder, respectively.
