Abstract
An electrode assembly includes an electrode saturated with electrolyte, and one or more ionically conductive and electronically insulating cellulose acetate coatings forming a continuous and conformal film adhered to and encapsulating the electrode.
Claims10
An electrode assembly comprising:
- a zinc electrode including active material particles held together via a binder or plasticizer to form a porous structure defining void spaces;
- an alkaline electrolyte occupying the void spaces;
- and
- one or more ionically conductive and electronically insulating cellulose acetate coatings forming a continuous and conformal film adhered to and encapsulating the zinc electrode and alkaline electrolyte, wherein the one or more coatings define pores having diameters less than 50 nanometers configured to block soluble zincate ions formed during charge and discharge of the zinc electrode from travelling through the one or more coatings and to discourage dendritic piercing of the one or more coatings.

An electrode assembly comprising:
- a zinc electrode including active material particles held together via a binder or plasticizer to form a porous structure defining void spaces;
- an alkaline electrolyte occupying the void spaces;
- and
- one or more ionically conductive and electronically insulating cellulose acetate sheets encompassing the zinc electrode and alkaline electrolyte, wherein the one or more sheets define pores having diameters less than 50 nanometers configured to block soluble zincate ions formed during charge and discharge of the zinc electrode from travelling through the one or more sheets and to discourage dendritic piercing of the one or more sheets.
