Abstract
Abstract An electrochemical battery including a plurality of modules interconnected electrically in series. Each module comprises a plurality of cells connected electrically in parallel. Each cell includes positive and negative electrodes. An electrolyte supply channel is individually connected to electrolyte spaces in each cell to supply electrolyte thereto. The cells of each module are fluidly interconnected at their lower ends in parallel by means of cross-channels. Optionally, these cells may also be fluidly interconnected at their upper ends in parallel by additional cross-channels.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
An electrochemical battery comprising: frame means; at least two modules mounted in said frame means and electrically interconnected in series, each module containing at least two cells electrically connected in parallel, each cell comprising: at least one positive electrode, a negative electrode, and an electrolyte space therebetween; and an electrolyte supply bi-channel connected to each electrolyte space independently of an adjacent space to supply each electrolyte space individually with electrolyte from a source of electrolyte, the electrolyte spaces of each module being interconnected fluidly in parallel at their lower ends by cross-channels to enable electrolyte to be transferred between said spaces.
Claim 2
Dependent Claim
101 words
An electrochemical battery comprising: frame means; at least two modules mounted in said frame means and electrically interconnected in series, each module containing at least two cells electrically connected in parallel, each cell comprising: at least one positive electrode, a negative electrode, and an electrolyte space therebetween; and an electrolyte supply bi-channel connected to each electrolyte space independently of an adjacent space to supply each electrolyte space individually with electrolyte from a source of electrolyte, the electrolyte spaces of each module being interconnected fluidly in parallel at their lower ends by cross-channels to enable electrolyte to be transferred between said spaces.
Claim 3
Dependent Claim
23 words
A battery according to claim 1 wherein said electrolyte spaces are further interconnected fluidly in parallel at their upper ends by additional cross-channels.
Claim 4
Dependent Claim
52 words
A battery according to claim 1 wherein said electrolyte supply bi-channels include inlet portions leading into respective ones of said electrolyte spaces, said cross-channels being larger in cross-sectional dimension that said supply bi-channel inlet portions to present sufficiently less resistance to liquid flow than that presented by said supply bi-channel inlet portions.
