An electrochemical cell 10 includes first and second electrodes 12 and 14 with an electrolyte system 26 disposed therebetween. The electrolyte system includes at least a first and second layer 28 and 30, the second layer 30 being used to absorb an electrolyte active species and to adhere the adjacent layer of electrode material to the electrolyte 26. The electrolyte system further includes a process for packaging and curing the electrolyte after it has been incorporated into a discrete battery device.

Method of making a gel electrolyte bonded rechargeable electrochemical

An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive electrode (20) and a negative electrode (30) with the electrolyte system (40) disposed therebetween. The electrolyte system is a polymer gel electrolyte system including a liquid electrolyte species which may be either aqueous or non-aqueous and a polymer gel electrolyte support structure. The polymer gel electrolyte support structure includes at least an non woven first polymer and a second polymer which is adapted to absorb the electrolyte active species. The first polymer is a fibrous polymer to reduce swelling of the gel electrolyte in the presence of the electrolyte active species, and further to enhance mechanical integrity of the support structure.

Non woven gel electrolyte for electrochemical cells

An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive electrode (20) and a negative electrode (30) with the electrolyte system (40) disposed therebetween. The electrolyte system is a polymer gel electrolyte system including an electrolyte active species which may be either aqueous or non-aqueous and a polymer gel electrolyte support structure. The blended polymer gel electrolyte support structure includes at least a first phase adapted to absorb or otherwise engage the electrolyte active species disposed on and through the pores of a second phase which is substantially inert and does not absorb the electrolyte active species.
