A solid electrolyte for a negative electrode of a secondary battery includes a first porous solid electrolyte having a first surface; a first coating on the first surface of the first porous solid electrolyte; an adhesive electrolyte layer on the first porous solid electrolyte; and a second porous solid electrolyte on the adhesive electrolyte layer, the second porous solid electrolyte having a second surface; wherein the first porous solid electrolyte and the second porous solid electrolyte each have an ionic conductivity effective for a deposition metal; and wherein a surface of the first coating is less favorable for deposition of the deposition metal than the second surface of the second solid electrolyte. An electrode assembly and an electrochemical cell including the solid electrolyte and method for the manufacture thereof are also described.

Solid electrolyte for a negative electrode of a secondary battery and methods for the manufacture of an electrochemical cell

A heterogeneous electrical energy storage system (HESS) is managed by determining a power demand of a dynamic electrical power load in a system having multiple rechargeable energy storage components, each of the energy storage components having a respective capacity, energy delivery rate, energy density, specific energy, and cycle characteristic. In response to determining the power demand of the electrical power load, one or more of the energy storage components are discharged to supply power to the electrical power load in accordance with at least one of: a respective remaining capacity measured for at least some of the energy storage components, and the power demand of the electrical power load relative to one or more respective rate limits currently applied to the energy storage components.
