Compliant Seal Structures For Protected Active Metal Anodes

View page
US Patent:
7824806, Nov 2, 2010
Filed:
Aug 8, 2006
Appl. No.:
11/501676
Inventors:
Steven J. Visco - Berkeley CA, US
Yevgeniy S. Nimon - Danville CA, US
Lutgard C. De Jonghe - Lafayette CA, US
Bruce D. Katz - Emeryville CA, US
Alexei Petrov - Walnut Creek CA, US
Assignee:
PolyPlus Battery Company - Berkeley CA
International Classification:
H01M 4/40
H01M 4/76
H01M 2/08
US Classification:
4292319, 429247, 429304, 429322
Abstract:
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.

Polymer Adhesive Seals For Protected Anode Architectures

US Patent:
8129052, Mar 6, 2012
Filed:
Sep 1, 2006
Appl. No.:
11/514678
Inventors:
Steven J. Visco - Berkeley CA, US
Yevgeniy S. Nimon - Danville CA, US
Lutgard C. De Jonghe - Lafayette CA, US
Bruce D. Katz - Emeryville CA, US
Alexei Petrov - Walnut Creek CA, US
Assignee:
PolyPlus Battery Company - Berkeley CA
International Classification:
H01M 4/40
H01M 4/76
H01M 2/08
US Classification:
4292319, 429246, 429304, 429322
Abstract:
Protected anode architectures for active metal anodes have a polymer adhesive seal that provides an hermetic enclosure for the active metal of the protected anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping. The architecture is formed by joining the protected anode to an anode container. The polymer adhesive seals provide an hermetic seal at the joint between a surface of the protected anode and the container.

US Patent:
8323820, Dec 4, 2012
Filed:
Jun 12, 2009
Appl. No.:
12/484063
Inventors:
Steven J. Visco - Berkeley CA, US

H01M 6/18
US Classification:
429126, 429142, 429304, 429322, 429323
Abstract:
Li/air battery cells are configurable to achieve very high energy density. The cells include a protected a lithium metal or alloy anode and an aqueous catholyte in a cathode compartment. In addition to the aqueous catholyte, components of the cathode compartment include an air cathode (e. g. , oxygen electrode) and a variety of other possible elements.
