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.

Claim (Index 15):
An electrode comprising:\n a current collector substrate; and an active material composite layered onto the substrate, wherein the active material composite comprises:\n a first layer adjacent the current collector substrate and including a plurality of first active material particles comprising silicon and configured to have a first solid state diffusivity and a first energy to lithiate per mole; and \n a second layer adjacent the first layer and including a plurality of second active material particles configured to have a second solid state diffusivity and a second energy to lithiate per mole; \n wherein the first solid state diffusivity is greater than the second solid state diffusivity, and the first energy to lithiate per mole is less than the second energy to lithiate per mole.
