Abstract

Provided is a terminal assembly for an electrochemical battery comprising a terminal connector; a conductive flat-plate with an electrically conducting perimeter; an electrically insulating tape member; and a terminal bipolar electrode plate. The electrically insulating tape member is in between the conductive flat-plate and the terminal bipolar electrode plate such that the electrically insulating tape member does not cover the entire surface area of the conductive flat-plate. The electrically conducting perimeter enables bi-directional uniform current flow through the conductive flat-plate between the terminal connector and the terminal bipolar electrode plate. Also provided is a battery frame member for a static rechargeable battery comprising a liquid diversion system; a gutter; a sealing member; a gas channel; and a ventilation hole. Also provided is a static rechargeable electrochemical battery comprising a pair of terminal assemblies, at least one bipolar electrode interposed between the pair of terminal assemblies, and a battery frame member.

Claims (19)

1 . A battery frame member for a static rechargeable battery comprising:

a liquid diversion system;

a gutter;

a sealing member;

a gas channel; and

a ventilation hole,

wherein the gutter is in a bottom portion of the battery frame member above a bottom portion of the sealing member and the gutter comprises a gutter shelf and a void underneath the gutter shelf, and

wherein the gas channel is in a top portion of the battery frame member directly above the ventilation hole.

2 . The battery frame member of claim 1 , wherein the liquid diversion system is in the top portion of the battery frame member directly below the ventilation hole.

3 . The battery frame member of claim 2 , wherein the liquid diversion system comprises a primary diverter and secondary blocking walls.

4 . The battery frame member of claim 3 , wherein the secondary blocking walls alternate top down and bottom up relative to the battery frame member.

5 . The battery frame member of claim 1 , wherein the sealing member extends around an inner periphery edge of the battery frame member.

6 . The battery frame member of claim 5 , wherein the sealing member either does not extend around a top portion of the inner periphery edge of the battery frame member or the sealing member extends around the inner periphery edge of the entire battery frame member.

7 . The battery frame member of claim 1 , wherein the gas channel is enclosed.

8 . The battery frame member of claim 7 , wherein the gas channel is covered by a lid that is attached to the battery frame member by means of welding, gluing, screwing, or snapping the lid to the battery frame member.

9 . The battery frame member of claim 1 , wherein the gas channel is integrated in the battery frame member.

10 . The battery frame member of claim 9 , wherein the gas channel is sealed from external environment with a plug.

11 . The battery frame member of claim 1 , wherein the battery frame member is substantially rectangular.

12 . The battery frame member of claim 1 , wherein a cathode carbon material rests on the gutter shelf.
