%X 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 gL�1 (L-LSG/D-MgAl-10) had the largest surface area of 49.335 m2g�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 mFcm�2 and 0.00296 mWhcm�2, respectively, at a current density of 0.08 mAcm�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
