Abstract
Aspects of the disclosure relate to electrode active materials for use in battery cells that include a lithium metal phosphate core having a more ionically conductive layer thereon. The layer of the ionic conducting material advantageously can increase lithium ion conduction of the active material by at least one order of magnitude relative to the core material alone. As such, electrodes may be fabricated with lower areal densities resulting in battery cells that have such electrodes with higher charge rates and potentially smaller physical dimensions.
