| Abstract | Different types of hybrid and gel polymer electrolytes (HPEs and GPEs) based on polymers and organic solvents combined with organic or inorganic gelation agents for Li/pyrite battery were studied. Ionic conductivity of 0.1-2.5mS/cm at room temperature (RT) was achieved for HPE and 5mS/cm for GPE. At 70°C tetraglyme (TG)-based HPE had conductivities of 1-4mS/cm, almost one order of magnitude higher than that of "dry" solid polymer electrolytes. An interfacial lithium/HPE resistance (RSEI) of 6-10Ωcm2 was stable for about 3000h. The specific capacity of the first discharge Li/pyrite cells with both HPEs and GPEs varied from 650 to 1000mAh/g. The reversible specific capacity at 70°C ranged from 250 to 600mAh/g; the maximal capacity is similar to that of solid-electrolyte Li/FeS2 batteries at 135°C. After the initial capacity loss, stable cycling behavior with 0.1% per cycle degradation rate was observed. © 2002 Elsevier Science B.V. All rights reserved. |
