“…Many studies have reported successful use of HPH as a processing step to produce advanced materials such as graphene films and inks (Tölle et al, 2012), polymer composites incorporating nanomaterials for improved mechanical, thermal and electrical properties (Appel et al, 2012;Chatterjee et al, 2012;Clausi et al, 2020;Shayganpour et al, 2019;Wu et al, 2021;Xu et al, 2020), and nanofluids which will be discussed. One particularly noteworthy application which has gained significant industrial traction recently, but is comparatively less explored in the academic literature is the production of graphene / carbon nanotube slurries for electrode coatings in batteries (Park et al, 2022;Wen et al, 2023).…”

Despite being a technology of several decades, high pressure homogenization (HPH) remains widely used in food and pharmaceutical industries, often as an essential unit operation in liquid product processing. Continual advances in the technology are made on multiple fronts, on equipment innovations by the manufacturers, new applications by users, and advances in process understanding by multidisciplinary scientists alongside subject matter experts amongst industry practitioners. While HPH is comparatively simple conceptually, the homogenization process involves complex engineering physics which is influenced by the varied processing conditions and highly diverse inputs with each use-case requiring its own treatment. The successful application of a HPH process indubitably requires practitioners to draw upon insights from multiple domains and the optimization for each case. Thus, this timely review aims to outline the more recent trends and advancements in HPH process understanding and novel applications involving HPH from both academic and industrial perspectives.

“…Recently, owing to the demand for energy storage systems, including electric car batteries, the requirement for the production of secondary batteries, particularly, Li-ion batteries (LiB) is significantly high [ 1 , 2 , 3 , 4 , 5 , 6 ]. In addition to the advancements in the search for alternatives for energy storage systems, research has been devoted to developing high-performance LiBs with better safety and lifetime [ 7 , 8 , 9 , 10 , 11 , 12 ]. Simultaneously, there has been considerable attention on environmental issues potentially arising from the waste or manufacturing procedures of LiB [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

The increase in demand for energy storage devices, including portable electronic devices, electronic mobile devices, and energy storage systems, has led to substantial growth in the market for Li-ion batteries (LiB). However, the resulting environmental concerns from the waste of LiB and pollutants from the manufacturing process have attracted considerable attention. In particular, N-methylpyrrolidone, which is utilized during the manufacturing process for preparing cathode or anode slurries, is a toxic organic pollutant. Therefore, the dry-based process for electrodes is of special interest nowadays. Herein, we report the fabrication of a cathode by a mortar-based dry process using NCM811, a carbon conductor, and poly(tetrafluoroethylene)binder. The electrochemical performance of the cathode was compared in terms of the types of conductors: carbon nanotubes and carbon black. The electrodes with carbon nanotubes showed an ameliorated performance in terms of cycle testing, capacity retention, and mechanical properties.

“…[6][7][8] For manufacuring engineering, the battery and electrode fabrication technique also enhances the energy density. [9][10][11][12] It has been focused to advance manufacturing technologies, where the goal is to increase energy density by maximizing the amount of active material and minimizing the conductive material and binder. In battery electrode manufacturing process, a slurry type mixture is cast onto the current collector foil, and the electrode matrix held together by an adhesive binder.…”

“…Polymers such as PVDF, styrene butadiene rubber (SBR), and polytetrafluoroethylene (PTFE), are commonly used as binders in battery electrodes. [11,[13][14][15][16][17] An electrochemically and oxidatively stable polymer is required for the positive electrode. Additionally, the Li ions of of the cathode active materials can be dissolved in the aqueous binder solutions.…”

Booster Adhesion of Crystalline Poly(vinylidene fluoride) Binder by Heat Treatment for Ni‐rich Layered Oxide Cathode in Lithium‐ion Batteries

High energy density of lithium‐ion batteries is crucial for highly efficient battery systems. Ni‐rich layered oxide cathode materials with a high specific capacity have garnered considerable interest. Ni‐rich cathode materials exhibit rather large volume fluctuations during charging and discharging, unlike traditional cathode materials. This study investigated the electrochemical performance of a Ni‐rich cathode with a focus on controlling binder adhesion of poly(vinylidene fluoride) (PVDF), which is the most feasible cathode binder for battery manufacturing, to mitigate the failure mode of volume changes. A simple heat treatment of 200 °C over melting point is effective to enhance binding force by altering nanoscale alignment of PVDF. The study evaluates the electrochemical properties of the Ni‐rich cathode with different levels of binder adhesion to determine the optimal binder conditions for high performance.
