Abstract
A novel pair of lead acid battery electrodes are proposed, which are bagged in terelyne cloth bag without having used any pasting to avoid paste mixer, pasting machine and oven etc. By increasing active material ratio to structural material, higher energy density is achieved. Uses of bag system for both negative and positive plate protect the plates from shredding of active materials on use of battery with lesser chance of failure.

A pair of bag-plate electrodes comprising, Pb—Ca structure grid and dry active lead oxide powder, the Pb—CA grid and dry active lead oxide power are added into and bagged in a terelyene cloth bag, sealed by Low Density Polythene glue.
A method of manufacturing bag-plate electrodes by inserting Pb—Ca structural grid in a terelyene cloth bag, adding dry active lead oxide powder into the bag and sealing the mouth of the bag by LDP glue.
A pair of bag-plate electrodes comprising:
- Pb—Ca structure grid and dry active lead oxide powder, the Pb—CA grid and dry active lead oxide power are added into and bagged in a terelyene cloth bag, sealed by Low Density Polythene glue;
- and
- the active powder for a positive plate is Pb3O4+PbO+Pb;
- and
- the active powder for a negative plate is PbO+Pb along with BaSO4 expander, Lignin and Carbon Black.
