Abstract
The development of efficient and stable cathode materials is a critical challenge in advancing lithium-ion battery (LIB) technology. This study proposes commercial LiFePO4 (LFP) coated with metal-azolate framework-5 (MAF-5). In this study, MAF-5 was carbonized (CMAF-5) and coated using in situ growth. X-ray diffraction patterns and infrared spectra show that LFP/CMAF-5 was successfully synthesized without disrupting the crystal structure of LFP. Electron microscopy confirmed CMAF-5coated onto LFP with a thickness of 1–5 nm. Electrochemical performance tests of LFP/CMAF-5 showed a specific charge–discharge capacity of 160 mAh/g at 0.1 C and a stable capacity retention of ∼110 mAh/g at 5 C, with excellent recovery after high-rate cycling. The low polarization resistance (Rp = 453.0 Ω) and high Coulombic efficiency (∼99 %) further confirm the suitability of the material for fast charge–discharge applications. This study provides a novel and scalable approach to improve LIB cathode materials using MAF-5 which offers promising potential for commercial energy storage applications.
