Electrode materials with a deformation capability are vital to the development of flexible supercapacitors. However, preparation porous carbons deformability remains challenging. Herein, compressible carbon foam has been successfully prepared using polydopamine/melamine sponge (PDA/MS) as precursor material. The structure was controlled by cetyltrimethylammonium bromide and K2CO3 template activating agent, respectively. resultant PDA/MS-derived (KDMC) three-dimensional network architecture exhibits excellent compressibility. specific surface area reaches ∼2890.0 m2 g–1. Furthermore, KDMC demonstrates outstanding capacitive performance, including capacitance (365.6 F g–1, 0.5 A g–1), good rate (86.6% retention from 10 cycling stability (only 1.9% loss after 10,000 cycles). To further demonstrate practical application potential KDMC, symmetric supercapacitor (KDMC//KDMC) assembled PVA/KOH gel electrolyte. device achieved an energy density 10.44 W h kg–1. This work presents robust method prepare electrode for high-performance

Porous carbons are ideal contenders for supercapacitor electrodes; however, challenges in creating a high surface area conjunction with controlled functionalization still exist. Herein, low cost and green route the synthesis of nitrogen sulfur codoped nanoporous biocarbons using casein dithiooxamide specific areas is reported. The textural properties tuned by varying temperature, wherein nitrogen‐doped porous carbon (N‐PC) shows (2132 m 2 g −1 ) ample microporosity (>90%). N S considerable (2068–1944 ). N‐PC displays capacitance 149 F at current density 0.5 A three‐electrode system. Interestingly, material N,S‐PC 500 an uplift ≈20% (178 capacitance. synergetic effect heteroatoms enhances due to provision additional electrochemical active sites conductivity. also reveals capacity retention 93.2% after 3000 cycles 5 . Overall, codoping prove be facile ploy enhance materials.
