Developing of high-energy, high-power-density energy storage devices is challenging. Despite being promising electrode materials for these devices, metal–organic frameworks (MOFs) have poor electrical conductivity and weak ligand–metal coordination. Here, the highly conductive MOF, Ni3(HITP)2, which comprises radially oriented microspheres, adopted as anode Li-ion capacitors (LICs). The half-cell demonstrates high reversible capacity (834 mAh g−1) at 50 mA g−1 with minimal reduction, attributable to participation C N functional groups ligand Ni2+ in redox reactions during charge/discharge. Especially, density theory calculations show that, apart from inner rings, outer rings Ni3(HITP)2 responsible Li + capacity. An LIC a commercial activated-carbon cathode specific (120.7 Wh kg−1) 89.2 W kg−1, nearly twice that graphite-based LICs, maintains 25.8 kg−1 even power (7.16 kW kg−1), over range 1–4.4 V, along cycling stability (76% retention 10000 cycles). proposed microspheres potential application high-performance devices.

Current research is focused on developing active materials through surface functionalization, porosity, composites, and doping for ultrafast electric double layer capacitors (EDLCs). In this study, deviating from existing strategies materials, we designed tunable 3D microgrid-patterned (MP) morphologies Ni foams used as current collectors using SUS meshes rigid stamps during roll pressing. The geometries of the MP-Ni were controlled to standard mesh scales 24, 40, 60 (denoted 24MP-Ni, 40MP-Ni, 60MP-Ni, respectively). three samples with different microgrid sizes presented geometries, such root-mean-square roughness (Rrms), skewness (Rsk), width/depth patterns. Consequently, 40MP-Ni demonstrated an optimized geometry high Rrms (35.4 μm) Rsk (−0.19) values, which facilitated deep slurry infiltration increased its contact area material. Surface optimization enabled reversible charge transport kinetics owing relaxed electron transfer resistance robust adhesion material compared bare foam. EDLC electrodes achieved ultrafast-rate capability (96.0 F/g at 20 A/g) longevity (101.9% capacity retention after 5000 cycles 5 without specific modification
