Abstract:
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.
