Online ahead of print.ABSTRACTThe growing demand for renewable energy storage has driven the rapid development of supercapacitors. However, the low energy density of supercapacitors has severely limited their application in systems requiring both high power and energy. This study addresses this limitation through a nanoarchitectonics-driven strategy that integrates biodeterioration, chemical activation, and air oxidation to hierarchically construct bamboo-derived porous carbon electrodes for zinc-ion hybrid supercapacitors (ZIHCs). Biodeterioration facilitated the pre-degradation of lignocellulose, enhancing subsequent ZnCl2 activation to yield a specific surface area of 902.66 m2·g-1 and a specific capacitance of 310.91F·g-1 at 1 A·g-1 in three-electrode tests. The assembled symmetric supercapacitors achieved energy densities of 12.63 Wh·kg-1 at 225.41 kW·kg-1. In ZIHCs, PAC-Zn achieved a remarkable energy density of 87.12 and 39.16 Wh·kg-1 at power densities of 417.15 and 33.85 kW·kg-1, respectively, and could retain 87.19% capacitance after 5,000 cycles at 10 A·g-1. Mechanistic analysis confirmed that biodeterioration enhances surface heterogeneity and reduces crystallinity, creating nucleation sites for ZnCl2 to etch interconnected pores. Molecular dynamics confirmed the preferential Zn2+ occupancy within mesopores (93.27%), directly linking the hierarchical pore engineering to ion accessibility and electrochemical performance.PMID:42735852 | DOI:10.1016/j.biortech.2026.135860
