a Detailed FTIR spectra of CCM, PVDF, and CCM-LFP at 1650–460 cm−1 region. b XRD and c DSC spectra of PVDF, CCM and CCM-PVDF. d Cycling performance of CCM-LFP | |Li (mass loading of 1.5 mg·cm−2) and Al-LFP | |Li (mass loading of 0.97 mg·cm−2) at 3 C. e Capacity fade versus current rate for various LFP-based cathodes42,43,44,45,46,47,48. f AC impedance spectra of CCM-LFP | |Li and Al-LFP | |Li. g Photographs exhibit the disassembled cells after the 500 charge-discharge cycles at 3 C. Photos of CCM-LFP and Al-LFP before (h) and after (i) 10 s of sonication.
