TECHNOLOGY FOCUS - POLYMERS - Preferred Components: (2) comprises an active electrochemical particulate material and an ionomeric polymer (preferably lithium salt). (3) comprises a polymer and a polar aprotic liquid. The polymer comprises monomer units of vinylidene fluoride and per fluoroalkenyl monomer (2 - 50 mol.%). The monomer has a pendant group comprising a radical of formula -(OCF2CFR)aOCF2(CFR')bSO2X-(M+)(YZc)d.R and R' = F, Cl or 1-10C perfluoroalkyl optionally substituted by at least one ether oxygen;a = 0, 1 or 2;b = 0 - 6;M+ = H+ or a univalent metal cation;X = O, C or N;R3 = 1-6C alkyl optionally substituted with at least one ether oxygen or an optionally substituted aryl;Rf = 1-10C perfluoroalkyl optionally substituted by at least one ether oxygen;R'f = -(RfSO2N-(M+)SO2)mR'f optionally substituted with at least one ether oxygen;m = 0 or 1;Rf = -CnF2n-;R' = -CnF2n+1;n = 1 - 10.Provided that d is 0 when X is O and d is 1, or c is 1, when X is C and c is 0 when X is N. When c is 1, Y and Z are CN, SO2Rf, SO2R3, P(O)(OR3)2, CO2R3, P(O)R32, C(O)Rf, C(O)R3 or Y and Z together form cycloalkenyl groups. When c is 0, Y is -SO2R'f. (4) comprises an ionomeric polymer and at least one carbon having a surface area of at least 200 m2/g.Preferred Process: (12) is made by (i) combining (2) and (3) to form a combined mass having a fusing temperature at which the mass fuses to form a plastically formable mass; (ii) mixing the combination at a temperature below the fusing temperature, and to allow the combined mass to densify to a density of at least 50% lower than the weighted average density of all the components. (30) comprises a first slot and a second slot. The simultaneous forcing step involves forcing (13) into first slot and (23) into the second slot on to (40).Preferred Mass: (12) has a bulk density of at least 50% lower than the weighted average density of all the components. (12) is fused by the application of heat or pressure to form plastically formable mass. EXAMPLE - A cathode layer contained the following composition (wt.%): Kynar Powerflex (RTM; poly(vinylidene fluoride)(9.6), LiCoO2 (62.7), Ensaco 350 (carbon black)(6.3), ethylene carbonate (10.7), propylene carbonate (10.7). The above blend was added to the hopper of an extruder. The feed barrel of the hopper was held at 100degreesC while the other two barrel where held at 115degreesC and 130degreesC. The mass had a residence time of 30 seconds. The melt was passed through a transfer line at 130degreesC, before extruding through a single slot die, gapped at 15 mils, at 130degreesC onto a polyester support. A comparative cathode composition was prepared similarly using a conventional extrusion process. The electrical conductivity of the film thus formed was measured for the test/ comparative and was found to be 195 s/cm/40 s/cm. Thus the results showed the improved electrical conductivity for the test film.
