Electrophoretic deposition as a fabrication method for Li-ion battery electrodes and separators - A review

Electrophoretic Deposition (EPD) is one of the alternative methods to fabricate and enhance the performance of Li-ion batteries. It enables the fabrication of electrodes with outstanding qualities and different electrochemical properties by the great domination over various parameters. EPD facilitates the processing of electrodes by binder-free grafting of nanomaterials, such as graphene derivatives, carbon nanotube, and nanoparticles, into the battery electrodes. It also enables the assembly of the free-standing electrodes with 3D structure and provides possibilities, such as the fabrication of the electrodes with an oriented microstructure, even on 3D substrates to improve the energy or power density. In this review, after an introduction to EPD, the effect of EPD parameters on the properties of the prepared electrodes is reviewed. Then, EPD is compared with tape cast, and its advantages over the conventional method are evaluated. Also, employing the EPD method as an intermediate process is discussed. Finally, the application of EPD in the fabrication of separators is assessed, and the prospects for the future are described.

Automated summary

Electrophoretic Deposition (EPD) is an alternative method for manufacturing and improving the performance of Li-ion batteries. It allows the fabrication of electrodes with excellent quality and different electrochemical properties, as well as the incorporation of nanomaterials into the battery electrodes without binders. EPD also enables the assembly of freestanding electrodes with a 3D structure and the creation of electrodes with oriented microstructures on 3D substrates. This article provides an introduction to EPD, reviews the effects of EPD parameters on electrode properties, compares EPD with tape casting, discusses its advantages over conventional methods, and evaluates its application in separator fabrication.
