ABSTRACT:
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 blended polymer gel electrolyte system including a liquid electrolyte species which may be either aqueous or non-aqueous and a blended 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 and a second phase which is substantially inert and does not absorb the electrolyte active species. The second phase may be divided 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.
