“…01-071-4919) were indexed and quantified by XRD and TIMA spectra (as illustrated in Figure A,B). These spinel-type manganese ferrite minerals are stable even in acid solution (pH < 3.5) and thus can prevent Fe and Mn ions from leaching during Ce recovery process.…”

“…Therefore, researchers try to achieve the conductive functionalization of polar materials or select polar adsorption materials with excellent conductivity to modify the separator to improve the comprehensive performance of lithium–sulfur batteries. For example, Yang Wang et al( Figure 3 A,B) [ 45 ] successfully modified the polypropylene (PP) separator for the first time by using the binary transition metal oxide MnFe 2 O 4 prepared by co-precipitation. The bifunctional modified separator decorated with MnFe 2 O 4 and conductive acetylene black (AB) effectively hinders the diffusion of polysulfide compounds due to the synergy of chemical adsorption and physical limits.…”

“…The result indicates that 10%CG-AB-modified separators significantly inhibits the self-discharge phenomenon of the Li-S battery. [39] For understanding the impact of 10%CG-AB-modified separator on battery performance, the EIS of PP, AB/PP, and 10%CG-AB/PP separators is recorded in Figure 3a. For fresh batteries, it can be seen that the Nyquist diagrams of all uncycled cells generally are made up of a semicircle in the high-frequency region and an inclined line in the low-frequency region, representing the charge-transfer resistance (R ct ) and Warburg impedance (Z w ), respectively.…”
