Abstract
The invention provides a slurry, such as a lead-acid battery slurry, comprising a polyelectrolyte comb copolymer and lead oxide. Use of polyelectrolyte comb copolymers results in a slurry with low viscosity. In addition, the use of polyelectrolyte comb copolymers controls the growth (e.g., size, morphology and location) of the inactive species, and thus, improves battery cycle life.
