Nitrogen and boron co-doped densified laser-induced graphene for supercapacitor applications

This study demonstrates a facile and versatile approach to the fabrication of N and B co-doped and simultaneously densified laser-induced graphene (NB-dLIG) based on a duplicate laser pyrolysis method for supercapacitor applications. The LIG obtained after the first laser pyrolysis is coated with an additional thin layer of polyamic acid /H3BO3 and additionally irradiated with a laser, resulting in the simultaneous densification and...
