Abstract

A method for configuring a non-lithium-intercalation electrode includes intercalating an insertion species between multiple layers of a stacked or layered electrode material. The method forms an electrode architecture with increased interlayer spacing for non-lithium metal ion migration. A laminate electrode material is constructed such that pillaring agents are intercalated between multiple layers of the stacked electrode material and installed in a battery.
