Claim 2:
3. An electrochemical cell which comprises: an anode; a cathode; and interposed therebetween is a solid-electrolyte which is a fire-resistant, non-flammable film which comprises:
a polymeric matrix;
a plasticizer;
a lithium salt; and
AlxLi7-xLa3Zr1.75Ta0.25O12 where x ranges from 0.01 to 0.2 (LLZO), wherein the LLZO are nanoparticles with diameters that range from 20 to 2000 nm wherein the polymer matrix comprises PEGDA which comprises 15 to 25 wt % of the film, the plasticizer comprises succinonitrile (SCN) which comprises 20 to 50 wt % of the film, the lithium salt comprises LiTFSI which comprises 30 to 40 wt % of the film, and the LLZO comprises 15 to 25 wt % of the film and wherein the film is free standing and has a thickness that ranges from 100 to 900 μm and the film is thermally stable up to 150° C.
