A novel approach was developed to locally fabricate planar lithium-ion batteries using composite electrode materials. The method involved electrophoretic deposition to create a composite cathode material comprising NCA and Super C45, while the anode was formed through localized electrochemical deposition of germanium nanofibers. This technique successfully formed planar batteries with heterogeneous composite electrodes on a single plane, offering advantages such as efficient ion transport, minimized electrode polarization, and enhanced electrochemical performance. The integration of electrochemical and electrophoretic deposition methods allowed for precise control of layer composition and deposition parameters, optimizing the properties of planar batteries in terms of specific capacitance and electrical conductivity. The study also focused on laser engraving topology and optimized modes for planar battery structures, enabling the integration of multiple processes in a single manufacturing cycle. Capacitive characteristics were assessed using specialized polypropylene tooling, and the planar battery prototypes demonstrated comparable capacity (4 µAh) to existing commercial alternatives.
