Patent number: 8404388Abstract: Protected anode architectures have ionically conductive protective membrane architectures that, in conjunction with compliant seal structures and anode backplanes, effectively enclose an active metal anode inside the interior of an anode compartment. This enclosure prevents the active metal from deleterious reaction with the environment external to the anode compartment, which may include aqueous, ambient moisture, and/or other materials corrosive to the active metal. The compliant seal structures are substantially impervious to anolytes, catholyes, dissolved species in electrolytes, and moisture and compliant to changes in anode volume such that physical continuity between the anode protective architecture and backplane are maintained. The protected anode architectures can be used in arrays of protected anode architectures and battery cells of various configurations incorporating the protected anode architectures or arrays.Type: GrantFiled: October 28, 2009Date of Patent: March 26, 2013Assignee: PolyPlus Battery CompanyInventors: Steven J. Visco, Yevgeniy S. Nimon, Lutgard De Jonghe, Bruce D. Katz, Alexei Petrov
