N2  - Background: Innovations in the synthesis of hybrid materials have led to technology advancement of the microsupercapacitor. Delaminated layered double hydroxide (LDH) reduces self-agglomeration and increases energy density in graphene-based supercapacitors. The incorporation of delaminated LDH with oil palm lignin derived laser scribed graphene in neutral PAAS/K2SO4 gel electrolyte for flexible microsupercapacitor applications was investigated. Method: Various concentrations of positively charged sucrose-delaminated Mg-Al LDH nanosheets produced through the coprecipitation method were hybridised with negatively charged oil palm lignin-derived laser scribed graphene (L-LSG) through electrostatic interaction. Significant Findings: Hybrid laser scribed graphene developed from delaminated Mg-Al LDH at a concentration of 10 gLâ??1 (L-LSG/D-MgAl-10) had the largest surface area of 49.335 m2gâ??1. The incorporation of Mg-Al LDH nanosheets on l-LSG were further validated by FESEM, TEM, XRD, Zeta potential and other characterizations. It also had the highest areal capacitance and energy density, measuring 40 mFcmâ??2 and 0.00296 mWhcmâ??2, respectively, at a current density of 0.08 mAcmâ??2. The fabricated microsupercapacitor has exceptional bending capabilities and capacitance retention of 89.2 after 5000 cycles. In summary, by inducing additional pseudocapacitance, delaminated Mg-Al LDH improved the overall effectiveness of the oil palm lignin derived graphene electrode compared to pristine graphene. © 2023 Taiwan Institute of Chemical Engineers
