TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Process: The method (P1) further comprises mixing the powdered material (M2) with solution of the binder to form dispersion; milling the dispersion to form coatable mixture; coating the mixture onto the current collector; and drying the coated current collector.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The powdered material (M1) further comprises material selected from silver, tin, bismuth, carbon, lead, antimony, germanium, zinc, gold, platinum, palladium, arsenic, aluminum, gallium, indium, thallium, molybdenum, niobium, tungsten, tantalum, vanadium, chromium, zirconium, yttrium, lanthanide and/or actinide (preferably graphitic carbon). The powdered material (M1) comprises (mole%) silicon (65-85), iron (5-12), titanium (5-12), and carbon (5-12).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The lithium sulfonate is selected from polystyrenesulfonate and polysulfonate fluoropolymer. The lithium polysulfonate fluoropolymer is derived from polysulfonic acid fluoropolymer that comprises a substantially fluorinated backbone and pendant of formula HO3S-(CFRf)a(CFRf)b-Z1-(CFRf)c(CFRf)d-Z2-. The binder (B1) is selected from poly(ethylene-alt-maleic acid) Li salt, poly(acrylic acid-co-maleic acid) Li salt, poly(methyl vinyl ether-alt-maleic acid) Li salt, and poly(2-acrylamido-2-methyl-l-propanesulfonic acid) Li salt. The polyacrylate comprises at least lithium (50 mole%) with respect to the molar amount of acidic groups on the polyacrylate.a, b, c, and d=0-3;c+d= plus minus 1;Z1 and Z2=O or single bond;andRf=F or substantially fluorinated, branched or unbranched (1-15C) fluoroalkyl, fluoroalkoxyl and fluoroether each containing 0-4 oxygen atoms. EXAMPLE - An electrode composition (test) was prepared (wt.%) using KETJEN (RTM: black conductive carbon) (1.2), Si70Fe10Ti10C10 powder (60), MCMB-1028 (RTM: graphite) (32) and deionized water. A comparative electrode composition was prepared using graphite (1 g), Si70Fe10Ti10C10 (0.1 g), KYNAR 741 (RTM: polyvinylidene fluoride) and N-methyl pyrrolidine (2.5 g). The electrodes were used in a cell. The irreversible capacity loss was calculated for test/comparative electrodes and the result showed the capacity loss/cycle (%) was 0.026/0.157 respectively.
