Abstract
A method for the manufacture of a paste composition suitable for the production of an electrode for lead-acid battery, including mixing a carbon nanofiller/lead oxide composite of a first particulate size with sulphuric acid, water and further lead oxide of a second particulate size. Also, the paste thus obtained, the composite used in its manufacture, and the electrode and lead-acid battery obtained from this paste.
Claims20
Method for preparing a paste composition suitable for the production 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.
Composite material comprising raw or oxidized carbon-based nanofillers, and lead oxide of a first particulate size, in a weight ratio of carbon-based nanofillers relative to lead oxide ranging from 5:95 to 20:80.
