Abstract
A battery includes a plurality of bipolar electrodes which include a wall, positive electrode material disposed on one side of the wall, and negative electrode material disposed on another side of the wall. Electrolyte chambers separate the electrodes. At the top of each electrolyte chamber a gas lock is provided. The gas locks are fluidly interconnected by fluid conduits. The conduits communicate with the gas locks at a level disposed below the top of the electrolyte chamber. Pressure build-ups in one electrolyte chamber can thus be distributed to the gas locks of other electrolyte chambers. Hydrophobic plugs can be disposed within the conduits which permit the passage of gas, but restrict the passage of electrolyte.

In a chemoelectric battery comprising a plurality of bipolar electrodes;
- each electrode including an electrically conductive separating wall which is impermeable to electrolyte, negative electrode material disposed on one side of said separating wall, and positive electrode material disposed on the other side of said separating wall, said electrodes being separated by an electrolyte-containing chamber, the improvement wherein each electrolyte chamber includes a gas lock, with the gas locks being fluidly interconnected by means of fluid conduits, said conduits communicating with said gas locks at a level disposed below the top of the electrolyte chamber.
A method for eliminating gas generated in a battery having a plurality of bipolar electrodes and electrolyte chambers therebetween comprising the steps of admitting such gases into a gas lock located at the top of each electrolyte chamber, and conducting such gases from one gas lock to another, so that gas generated in one gas lock can be distributed to a plurality of other gas locks.
