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.
Bibliographical noteFunding Information:
Cathodic EPD was initially commercialized by PPG, which became an industrially relevant process for the corrosion protection of vehicle panels. Of late, PPG acquired financial support of $2.2‐million from the US Department of Energy (DOE) for investigating the comparative application of EPD against standard slot‐die casting for the preparation of LiB electrodes. PPG's process concentrates on tackling engineering approaches of EPD to prepare sophisticated LiB materials and devices in collaboration with Oak Ridge National Laboratory in Tennessee. 280
