2022年8月1日 · This work provides an effective strategy to introduce reversible Mn 2+ /Mn 4+ double redox couple into Mn-based layered oxides to effectively address the J-T effect, which provides an alternative avenue to design high-performance Mn-based cathode materials for SIBs.

5 天之前 · Inspired by these advancements, in this work, a manganese-doped Ni 7 P 3 catalyst (denoted as Mn-Ni 7 P 3 /NF-1) supported on nickel foam was synthesized through hydrothermal and phosphorization methods [35], [36].The resulting Mn-Ni 7 P 3 /NF-1 catalyst displays a porous nanosheet morphology, which facilitates greater exposure of active sites and the formation of NiOOH in the electrolyte.

2024年9月1日 · Algae can promote biogenic oxidation of Mn (II) by accelerated O2− production. The inhibited Fe-S cluster activity of QJX-1 by algae can induce electron leakage. Decomposition of H 2 O 2 can benefit the transformation of intermediate Mn (III) ions. The phenomenon can be found with many prevalent algae species in algae blooms.

2022年11月25日 · During the discharge process, the signal of Mn─O/Mn─Mn increases after discharge to 3.0 V, suggesting the high reversibility of the local structure of S-LRMO. However, the intensity of Mn─O/Mn─Mn decreases significantly when delithiated to 2.0 V, which derives from the following reduction process of Mn ions.

2018年7月30日 · Here we conduct both in situ and ex situ studies on a typical LMR material (Li 1.2 Ni 0.15 Co 0.1 Mn 0.55 O 2) during charge–discharge cycling, using multi-length-scale X-ray spectroscopic and...
