Is it possible that solder, being a tin / lead mix will have a lower melting point than pure lead?


Oh yes. You can solder lead easily.

IIRC batteries are 'burned' rather than soldered, using lead not solder.

Wiki fwiw:
'All intra-cell and inter-cell connections are of the same lead alloy as that used in the grids. This is necessary to prevent galvanic corrosion.'
