Abstract
A storage battery plate has lead bars positioned within channels defined by a grid of plastic strips. These channels also contain the active mass. The channels are closed off by electrolyte permeable cover layers.
Claims12
A storage battery plate comprising:
- a grid formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass;
- a grid of lead bars recessed within said channels;
- active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed;
- and
- electrolyte permeable fibrous mats covering said grid on both sides
- said mats being firmly attached to said exposed edges of plastic strips and plastic cross-connections.
3 more elements
A storage battery plate assembly comprising:
- a plurality of grids formed of plastic strips and plastic cross-connections between said strips, said strips defining channels for containing the active mass;
- a plurality of grids of lead bars, each said grid being recessed within the channels defined by one of said plastic grids;
- active mass substantially filling said channels and surrounding said recessed lead bars, said active mass being positioned to leave edges of said plastic strips and cross-connections exposed;
- and
- electrolyte permeable fibrous mats covering each said grid on both sides and firmly attached to said exposed edges of plastic strips and plastic cross-connections, different ones of said grids being placed adjacent each other to form the plates of said assembly, without intervening separator.
