Abstract
A reference electrode assembly includes a porous separator and a continuous electroactive material layer disposed on a surface of the porous separator. The electroactive material layer includes between about 20 wt. % and about 80 wt. % of an electroactive material and between about 20 wt. % and about 80 wt. % of an electrically conductive material. A loading density of the electroactive material is greater than or equal to about 0.01 mAh/cmto less than or equal to about 0.1 mAh/cm. The electroactive material can be selected from the group consisting of: LiFePO(LFP), lithium-aluminum alloys, lithium-tin alloys, and combinations thereof; and the electrically conductive material can be selected from the group consisting of: carbon black, carbon nanotubes, graphite, metal nano-micro particles, and combinations thereof. The continuous electroactive material layer is disposed on the surface of the separator using a one-step process selected from spin-coating electrode casting, ink-jet printing, and spray-coating.
