20.500.12556/RUL-142004 Nanostructured poly(hydroquinonyl-benzoquinonyl sulfide)/multiwalled carbon nanotube composite cathodes improved synthesis and performance for rechargeable Li and Mg organic batteries Cost-effective, simple, and easily reproducible synthesis methods of polymers are of profound significance when it comes to extracting high battery performance metrics from polymeric redox-active materials. This work reports a procedure for the solvothermal synthesis of a poly(hydroquinonyl-benzoquinonyl sulfide) (PHBQS) polymer and the development of its nanostructured composites with multiwalled carbon nanotubes (MWCNTs). Polymers are tested as high-performance cathode materials for Li$^+$ and Mg$^{2+}$ batteries. In configurations, compared to neat PHBQS, the PHBQS@5%MWCNT cathode exhibits superior electrochemical performance with high active material utilization owing to improved ion/electron transport pathways. Galvanostatic characterization of the PHBQS@5%MWCNT cathode in lithium batteries exhibited peak capacity up to 358 mAh g$^{−1}$ at a current density of 50 mA g$^{−1}$ (C/8) and excellent rate performance with a discharge capacity of 236 mAh g$^{−1}$ maintained even at high current density of 10C. The galvanostatic characterization in Mg batteries reveals more sluggish kinetics with a stable capacity of 200 mAh g$^{−1}$ at 50 mA g$^{−1}$. batteries carbon nanotubes electrical conductivity electrodes polymers materiali polimeri sinteze magnezij baterije true false true Angleški jezik Slovenski jezik Članek v reviji 2022-10-14 12:28:48 2022-10-14 12:28:50 2022-11-09 03:54:42 0000-00-00 00:00:00 2022 0 0 Str. 6378−6388 iss. 14 Vol. 34 Jul. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1/.2 0897-4756 10.1021/acs.chemmater.2c00862 124763139 acs.chemmat.pdf acs.chemmat.pdf 1 45196F18EF08BDB40895E2A67F7D5D1B 5e0ef851e34233ea95ac280216a5e440aaa35e35409b2cc98676a1bb7a8255ae d2b687f9-5f3a-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163812 https://pubs.acs.org/doi/10.1021/acs.chemmater.2c00862 1 f2b71573-4baa-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=163242 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
