Pure MOF materials have inherent defects of low conductivity and poor structural toughness, limiting their independent application in supercapacitor electrodes. MOF composite materials compounded with MXene, LDH and carbon materials perfectly make up for single-material shortcomings and become core electrode materials for high-performance supercapacitors. This article introduces their exclusive application advantages. For energy storage material matching, refer to Complementary Advantages of MOF, MXene and LDH in New Energy Storage Field.
1. Ultra-High Specific Capacity Brought by Porous Structure
MOF’s adjustable porous structure provides abundant ion transmission and storage space for supercapacitors. Composite structure avoids pore collapse caused by single MOF structural fragility, greatly improving electrode specific capacity. Compared with traditional carbon electrode materials, MOF composite electrodes increase supercapacitor energy density by 25%–50%.
2. Improved Conductivity & Fast Charge-Discharge Performance
Compound conductive MXene and carbon nanotube materials build high-speed electron transmission networks inside MOF electrodes, solving the poor conductivity defect of pure MOF. This composite structure realizes rapid ion migration and electron transfer, significantly improving the fast charge-discharge response speed of supercapacitors.
3. Enhanced Cycle Stability & Structural Toughness
Pure MOF electrodes are prone to structural damage and capacity attenuation during long-term charge-discharge cycles. LDH and carbon composite layers effectively buffer volume expansion and contraction, protecting MOF crystal structure. Qualified MOF composite supercapacitors maintain more than 90% capacity after 10,000 cycles.
