The invention relates to an article comprising: a) one or more stacks of battery plates comprising one or more bipolar plates; b) located between each plate is a separator and a liquid electrolyte; further comprising one of more of the features: 1) c) the one or more stacks of battery plates having a plurality of channels passing transversely though the portion of the plates having the cathode and/or the anode deposited thereon; and d) i) one or more seals about the periphery of the channels which prevent the leakage of the liquid electrolyte into the channels, and/or posts located in one or more of the channels having on each end an overlapping portion that covers the channel and sealing surface on the outside of the monopolar plates adjacent to the holes for the transverse channels and applies pressure on the sealing surface of the monopolar plates wherein the pressure is sufficient to withstand pressures created during assembly and operation of electrochemical cells created by the stacks of battery plates; 2) c) a membrane comprising a thermoplastic polymer is disposed about the entire periphery of the edges of the stack of plates; 3) wherein the separator is in the form of a sheet having adhered to its periphery a frame; and 4) c) an integrated valve and integrated channel communicating with the valve.
(canceled)
An article according to claim 22 wherein the substrates of the monopolar and bipolar plates comprise sheets of thermoplastic polymer.
3-6. (canceled)
An article according to claim 22 wherein the bipolar plates comprise polymeric substrates having a plurality of openings passing through the substrates in communication with both faces of the substrates wherein one or more of the openings are filled with a conductive material which is in contact with both faces of the substrates.
An article according to claim 22 wherein the article further comprises one or more a valves adapted to release pressure in the sealed stacks of bipolar plates when the pressure reaches a predetermined pressure level which is below a pressure at which damage to the article could occur.
(canceled)
An article according to claim 22 wherein the substrates comprise one or more thermoset polymers with one or more thermoplastic polymers attached about the periphery of the thermoset polymers.
(canceled)
An article according to claim 22 further comprising the one or more stacks of battery plates having a plurality of channels passing transversely though the portion of the plates having the cathode and/or the anode deposited thereon and posts located in one or more of the channels having on each end an overlapping portion that covers the channel or a membrane comprising a thermoplastic polymer is disposed about the entire periphery of the edges of the stack of plates so as to form a seal about the periphery of the edge of the plates which seal prevents the electrolyte from flowing outside of the stack of plates wherein the membrane, posts, or both, are formed by molding.
14-16. (canceled)
An article according to claim 22 wherein a valve is connected to the integrated channel.
18-21. (canceled)
An article comprising:
