A method of producing a powder mass for a lithium battery, the method comprising: (a) providing a solution containing a sulfonated elastomer dissolved in a solvent or a precursor in a liquid form or dissolved in a solvent; (b) dispersing a plurality of particles of a cathode active material in the solution to form a slurry; and (c) dispensing the slurry and removing the solvent and/or polymerizing/curing the precursor to form the powder mass, wherein the powder mass comprises multiple particulates and at least a particulate comprises one or a plurality of particles of a cathode active material being encapsulated by a thin layer of sulfonated elastomer having a thickness from 1 nm to 10 μm, a fully recoverable tensile strain from 2% to 800%, and a lithium ion conductivity from 10.sup.−7 S/cm to 5×10.sup.−2 S/cm at room temperature.

Cationic polymers are provided that comprise monomeric units of Formula (V). (V) Each asterisk (*) indicates an attachment position to another monomeric unit; R is hydrogen or methyl; each R.sup.2 is each independently an alkyl, aryl, or a combination thereof; L is a linking group comprising an alkylene group; and +R.sup.3 is a cationic nitrogen-containing group free of any N—H bonds. Membranes formed from said cationic polymers, devices including such membranes, and methods of making such cationic polymers are also provided.

Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.
