Abstract
Electrochemical cells of the present disclosure may include one or more multilayered electrodes. Each multilayered electrode may be configured such that active materials of the layer closest to the current collector have a lower energy to lithiate per mole, a higher energy to delithiate per mole, a different solid state diffusivity, and/or a different average particle size. This arrangement counteracts, for example, natural gradient fields and undesirable polarization found in standard lithium-ion batteries.
