1. A system for continuous roll-to-roll electrode processing with multiple lanes, the system comprising:
a heat treatment oven configured for applying pyrolysis concurrently to a plurality of carrier films, to convert a corresponding precursor composite film on each carrier film to a pyrolyzed composite film; and
a plurality of press rollers arranged in pairs, each pair of rollers configured for pressing a corresponding pair of first and second pyrolyzed composite films of the pyrolyzed composite films onto a corresponding current collector film of a plurality of current collector films, wherein:
each pair of press rollers is configured to press the corresponding first and second pyrolyzed composite films onto corresponding first and second sides of the corresponding current collector film from the plurality of current collector films,
the corresponding first and second pyrolyzed composite films are applied from two different carrier films from the plurality of carrier films, and
the two different carrier films of the plurality of carrier films are separated after the pressing.
