Such electrodes enable direct translation of computational designs into 3D printable electrodes, including lithium ion microbatteries, and candidate designs in which the removal of certain features may actually increase voltage efficiency at a given current density. Despite the power of additive manufacturing, most printable inks and photocurable resins are poorly conducting. Efforts to enhance their conductivity have focused largely on incorporating a percolated network of metallic nanoparticles within polymer matrices to achieve electrical resistivities of ~10 -5 Ω cm. Alternately, van der Heijden et al. used stereolithography followed by pyrolysis to fabricate conductive carbon electrodes. While electroless metal plating has been employed in post-print processing for other applications, it has not previously been reported for 3D-printed porous electrodes.
