“…4AB, distinct CV plots revealed that biogenic Mn 2 O 3 with higher current was more active and had stronger EET ability than the purchased one. And the potential difference between the redox peaks is about 0.5 V, which belongs to the potential difference between Mn(II) and Mn(III)/Mn(IV) interconversion reaction (Guo et al 2015). Figure 4C shows the galvanostatic charge-discharge of Mn 2 O 3 .…”

While the peroxymonosulfate (PMS) advanced oxidation was regarded as an emerging method to degraded recalcitrant pollutant in soil, the design and synthesis of activator for PMS was still challenging. Here, by using Shewanella oneidensis MR-1, a representative model strain of dissimilatory metal reducing bacteria in soil and sediment, biogenic Mn2O3 nanoparticles was synthesized by the oxidizing of 5 mM Mn(II), to activate the PMS for phenanthrene degrading in soil. It was observed that 77.4% of phenanthrene was removed in soil with biogenic Mn2O3 whereas 55.7% was achieved with chemical synthesized Mn2O3, which was associated with their characterizations: biogenic Mn2O3 presenting faster electron transfer rate and owing to the higher ratio of Mn(III) to donate electrons to PMS. Moreover, the feasibility of this PMS advanced oxidation to soil remediation was further evaluated by the analysis of microbial community diversity. Considering that Mn is abundant in natural soil and groundwater system, biogenic Mn2O3 synthesized in-situ would be a new strategy for soil remediation.

“…LMO has a three dimensional spinel structure which improves the diffusion of lithium ions [12][13][14]. The electrochemical reactions are associated with the insertion and extraction of lithium ions between the cathode (LiM n 2 O 4 ) and the anode (lithium) [15][16][17]. NMC battery is one of the most successful lithium-ion batteries which balances the specific features of Lithium Cobalt Oxide (LCO) battery and LMO battery.…”

The Lithium-ion battery is one of the most common batteries used in Electric Vehicles (EVs) due to the specific features of high energy density, power density, long life span and environment friendly. With the development of lithium-ion battery technology, different materials have been adopted in the design of the cathodes and anodes in order to gain a better performance. LiM n2O4, LiN iM nCoO2, LiN iCoAlO2, LiF eP O4 and Li4T i5O12 are five common lithium-ion batteries adopted in commercial EVs nowadays. The characteristics of these five lithiumion batteries are reviewed and compared in the aspects of electrochemical performance and their practical applications.

“…Xie and co-workers 46 applied a templating method to synthesize a single-crystalline spinel LiMn 2 O 4 nanorod structure that exhibited a superior long cycle life, retaining 95.6% of the initial capacity aer 1000 cycles at a 3C rate, with no deterioration of the morphology. Compared with the one-dimensional structure, spherical or anomalous nano/ microscale pieces [49][50][51][52][53][54][55][56] are more prone to degradation and have bulk-like electrochemical performance due to their crystalline structure and size effectiveness. It should be noted that a porous cube structure as shown in Fig.…”

Spinel LiMn2O4 (LMO)-based composites, due to their combination of low toxicity, abundant natural resources, and excellent electrochemical performance, are regarded as promising candidate cathode materials for lithium ion batteries. Current energy storage demands are not being met with existing materials, however, because of their defects, such as fast capacity fading, low rate capability, and low specific capacity in practical applications. Manganese dissolution during electrochemical processes bears the major responsibility for capacity loss, apart from the electrolyte factor. Low electrical conductivity, low ionic diffusion efficiency, and large structural variation have adverse effects on the electrochemical performance of materials. With respect to these drawbacks, significant progress has been made recently on optimizing the performance of LMO-based cathode materials. In this work, we review recent progress in 1 structural design, designing composites with graphene/carbon nanotubes, crystalline doping, and coatings for improving the electrochemical performance of these cathode materials.
