A method for manufacturing a component comprising bombarding nanoparticles in a dispersion with a laser to transform the ligand and cause the nanoparticles to drop out of the dispersion and deposit onto a substrate; and bombarding additional nanoparticles in the dispersion with the laser to transform the ligand and cause the nanoparticles to drop out of the dispersion and deposit onto the nanoparticles previously deposited out of the dispersion.

A dry electrode manufacturing process employed for low cost battery through a dry mixing and formation process. A thermal activation renders the dry fabricated electrode comparable to conventional slurry casted electrodes. The dry electrode mixture results from a combination of a plurality of types of constituent particles, including at least an active charge material and a binder, and typically a conductive material such as carbon. The process heats the deposited mixture to a moderate temperature for activating the binder for adhering the mixture to the substrate; and compresses the deposited mixture to a thickness for achieving an electrical sufficiency of the compressed, deposited mixture as a charge material in a battery.
