Abstract The present invention provides a primary battery for high current loads. In order to fulfill the electrochemical parameters for giving high current discharge, it is necessary that the electrode area be increased extensively. Provision is thus made for compensating for gas evolution within the battery by including a pressure gradient device within said battery. This device is incorporated within a large void space within the battery and comprises an electrolyte dispenser in combination with a flexible, unperforated tube having a sealed end and an open end. The open end is closed by means of an electrolyte dispenser comprising a tight-fitting plastic cap having an aperture therethrough. This pressure gradient device is disposed concentrically within the cell, generally within one of the inner conductors of the cell, such as the anode conductor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
162 words
An alkaline primary battery comprising: a plurality of concentrically arranged interfitting individual cells, each of said cells comprising respectively an anode, a depolarizer cathode, and an activating electrolyte therebetween, each anode of said individual cells being electrically interconnected and each cathode of said individual cells being electrically interconnected to afford extensive surface areas to be acted upon by said electrolyte whereby a high current output is obtained from the battery; gas control means for controlling the internal gas pressure of said ceLls comprising a flexible, electrically non-conductive plastic tube having an open end and a closed end, said tube acting as an electrolyte displacer and as a reservoir of compressible gas, said gas being solely confined within said battery; an electrolyte dispenser closing said open end of said plastic tube, said dispenser comprising a tight-fitting plastic cap having a small bore therethrough to allow pressure equalization within said tube as said tube becomes compressed upon the generation of gas within said battery.
Claim 2
Dependent Claim
