Electrophoretic deposition (EPD) is a technique widely used for high throughput industrial processes. Here we show EPD as a route to manufacture low-cost, high areal capacity battery electrodes. Using non-toxic, quick-drying acetone as a solvent, we use EPD to fabricate lithium iron phosphate cathodes with high areal loadings of 50 mg/cm2. Higher electrode mass loadings substantially contribute to increasing the energy density while minimizing the overall cost of the battery materials by decreasing the ratio of inactive to active components. This work highlights the electrochemical performance of high areal loading EPD manufactured electrodes with capacities up to ~8 mAh/cm2. EPD is a promising technique to manufacture the next generation of nanoarchitecture electrodes with high energy density at reduced manufacturing costs.
