EPD of thick films for their application in lithium batteries

Electrophoretic deposition (EPD) is an appropriate tool to prepare thick film electrodes of lithium batteries, once optimized the different factors that affect to this coating method. Compared with other deposition methods, EPD has the ability to allow the simultaneous deposition of the active material, an additive conductor such as carbon black (CB) and a binder to improve the plastic properties of the deposit. However, for obtaining an appropriate electrochemical response they need so far to be compressed. With this simple process, the electrode performance is excellent in terms of the delivered capacity by the cell and the capacity retention on cycling.
