1. A system for creating a cell for a monopole or bipole lead acid battery, comprising:
a first carrier structure to receive a wet paste from a paster;
a second carrier structure to receive an electrode substrate;
a combining station at which to combine the first carrier structure and corresponding wet paste and the second carrier structure and corresponding electrode substrate into an assembly;
an ultrasonic welding system to receive the assembly and provide mechanical pressure and ultrasonic energy to the assembly; and
a removal station to remove at least one of the first and second carrier structures to create a modified assembly.
