Abstract
In a flexible non-aqueous electrochemical cell, the electrolyte resides substantially entirely within the porous anode, cathode, and separator. In manufacturing the flexible non-aqueous electrochemical cell, the volume within the cell available to receive the electrolyte is substantially limited to the pores of the anode, cathode, and separator.
Claims21
A non-aqueous electrochemical cell comprising:
- a negative electrode;
- a positive electrode;
- a porous separator positioned between said negative electrode and said positive electrode;
- an electrolyte solution comprising a liquid solvent and a conductive salt;
- and
- a flexible, fluid impermeable container containing said negative electrode, said positive electrode, said separator, and said electrolyte solution, wherein substantially all of said electrolyte solution fills the pores of both of said electrodes and said separator, and introduction of said electrolyte solution into the space between said electrodes and said flexible container is substantially prevented.
