Abstract
A battery unit cell with improved conductive sealing by shielding the positive tablet electrode with a conductive polymeric sheet such as a thermo-plastic rubber sheet dispersed with acetylene black. This improved sealing alleviates the adverse loss of moisture from the battery unit cell and enhances the shelf- or storage-life of batteries with cells with such improved sealing means or methods.
Claims11
An improved battery cell including a first electrode having a top surface and a bottom surface, a second electrode having a top surface and a bottom surface, an insulating separator separating said first electrode and said second electrode, an electrolyte supporting ion conductivity between said first and said second electrodes, said first electrode and said second electrode being stacked together so that the bottom surface of said first electrode is stacked adjacent to the top surface of said second electrode;
- said first electrode, said second electrode, said separator and an electrolyte being held together by a receptacle, said top surface of said first electrode being substantially covered by a conductive and non-porous layer made of a material which is generally corrosion resistant to the electrolyte.
