An electrode comprising a noble-metal free grid comprising lead, wherein the grid has an essentially PbO free PbO coating covering all, or essentially all of the surface of the grid. Also described is a method of forming an electrode, comprising applying an essentially PbO free PbO coating to a noble-metal free grid comprising lead, wherein the coating covers all, or essentially all of the surface of the grid.

Electrode

A plate making process for a lead acid battery which eliminates the need for steaming and curing steps to produce the active material. Mixing, reacting and crystallizing occur in a closed reactor under controlled temperature and mixing conditions to produce a paste having the desired crystal morphology. A polymer is then added to the paste to bind the crystals together and to produce desired rheological properties in the paste. The paste having the polymer addition is then pasted onto a grid where the paste is dried to form a battery plate of the lead acid battery. The process is applicable for both the positive and negative plates of a lead acid battery.

Plate making process for lead acid battery

A grid plate for high power lead acid battery having a plate ( ) covered with a conductive polymeric matrix ( ) of preferably polyaniline and its derivatives, which is then coated with nanoscale particles of active material ( ) such as lead sulfate and basic lead sulfate complexes.
