Method for preparing a paste composition suitable for the production of an electrode of an electrode for lead-acid battery, comprising:
- (a) providing a composite material comprising carbon-based nanofillers and lead oxide of a first particulate size, and
- (b) mixing said composite material with sulphuric acid, water, lead oxide of a second particulate size and, optionally, at least one reinforcing filler, to thereby obtain the paste composition,
- wherein the first particulate size is a different average size than the second particulate size,
- wherein the composite material is obtained by grinding the carbon-based nanofillers and lead oxide to a first particulate size.
