“…22 The deposition process occurred at a very high potential of up to 50 V. Moyer et al (2019) used EPD to deposit LFP on the 3D structures and exploited additional components such as Super C45 powder and a xanthan gum binder. 23 Yet, the resulting electrodes demonstrated sudden capacity fading. Sanchez et al 24 presented an electrophoretic coating of LFP/graphene oxide on carbon fibers.…”

Lithium iron phosphate (LiFePO4, LFP) is one of the most advanced commercial cathode materials for Li-ion batteries and is widely applied as battery cells for electric vehicles. In this work, a thin and uniform LFP cathode film on a conductive carbon-coated aluminum foil was besieged by the electrophoretic deposition (EPD) technique. Along with the LFP deposition conditions, the impact of two types of binders, poly(vinylidene fluoride) (PVdF) and poly(vinylpyrrolidone) (PVP), on the film quality and electrochemical results has been studied. The results revealed that the LFP_PVP composite cathode had a highly stable electrochemical performance compared with the LFP_PVdF counterpart due to the negligible influence of the PVP on the pore volume and size and retaining high surface area of LFP. The LFP_PVP composite cathode film unveiled a high discharge capacity of 145 mAh g–1 at 0.1C and performed over 100 cycles with capacity retention and Coulombic efficiency of 95 and 99%, respectively. The C-rate capability test also revealed a more stable performance of LFP_PVP compared to LFP_PVdF.

“…[88][89][90]98] But it still requires binders to make slurries, which may increase the portion of inactive components and also block electron conduction in electrodes. Directly growing or depositing active materials within the network [87,[93][94][95] is an alternative approach. For example, by growing FeS 2 nanowires within carbon nanotube sponges via a solvothermal method, our group fabricated a reticulate FeS 2 /CNT dual-nanowire aerogel as a free-standing LIB anode, which yielded a high areal capacity of 10.0 mAh cm −2 at a mass loading of 14.4 mg cm −2 after 100 cycles.…”

In recent decades, extensive nanomaterials and related techniques have been proposed to achieve high capacities surpassing conventional battery electrodes. Nevertheless, most of them show low mass loadings and areal capacities, which deteriorates the cell‐level energy densities and increases cost after the consideration of inactive components in batteries. Achieving high‐areal‐capacity is essential for those advanced materials to move out of laboratories and into practical applications, yet remains challenging due to the decreased mechanical properties and sluggish electrochemical kinetics at elevated mass loadings. In this paper, the previously reported strategies for promoting areal lithium storage performance, including material‐level designs, electrode‐level architecture optimization, and novel manufacturing techniques are reviewed. Sodium‐ion battery electrodes are discussed subsequently, emphatically on its difference with those for lithium storage. Pouch‐cell‐level energy densities based on high‐areal‐capacity electrodes with different thicknesses are also estimated. For each category of these strategies, working principles, advantages, and possible problems are analyzed, with typical examples presented in detail and a summary table comparing the structures and achieved performance. Finally, the features of the high‐areal‐capacity electrodes demonstrated in this review are concluded, and overlooked issues and potential research directions in this field are summarized.

“…Similarly, some researchers utilised EPD to fabricate a high-quality, conformal nanostructured carbon film, which was then loaded with sulphur through vapourphase sulfurization. 139,156 When tested as cathodes in Li-S batteries, these electrodes exhibited high capacities in excess of 1200 mAh/g À1 .…”

The applications of electrophoretic deposition (EPD) to the development of electrochemical energy storage (EES) devices such as batteries and supercapacitors are reviewed. A discussion on the selection of parameters for optimizing EPD electrode performance, such as light-directed EPD, co-deposition of active materials such as metal oxides and materials manufactured with high porosity and fibrous properties is highlighted. Additionally, means for overcoming obstacles in the improvement of the mechanical properties, conductivity and surface area of EES materials are discussed. The exceptional benefits of EPD such as low cost, small processing time, simple apparatus requirements, homogeneous coatings, binder-free deposits and selective modification associated with thickness and mass loadings leading to effective EES electrode materials are highlighted. Finally, EPD processes have evolved as modern manufacturing tools to produce technologically improved solid electrolytes and separators for lithium-ion and/or sodium-ion batteries, and further research and development programmes are encouraged towards industrialisation.
