“…20-0781). 26 No impurity phases are found in XRD patterns, indicating the substitution of Co by Mn could not change NiCo 2 O 4 spinel structure. Besides the diffraction peaks of NiCoMnO 4 , two additional small and broad diffraction peak around at 25° can be assigned to the disorderedly stacked graphene sheets.…”

“…These phenomena usually occur in transition metal oxide anode materials (Zhang et al, 2015 ; Guan et al, 2016 ), which can be attributed to the reversible growth of a polymeric gel-like film origination from kinetic activation process, and this can promote interfacial lithium storage. Therefore, the capacities gradually increase with extended cycling (Liu et al, 2018 ). It can be seen that LFM-650 can deliver a high discharge specific capacity of 925 mAh g −1 and own higher retention rate (88%, calculated based on the theoretical capacity of 1,050 mAh g −1 ) even at a current rate of 1 C after 500 cycles, which is far beyond LFM-600 (325 mAh g −1 ), LFM-680 (343 mAh g −1 ), and LFM-700 (337 mAh g −1 ), respectively.…”

A facile sol-gel process was used for synthesis of LiFe(MoO4)2 microcrystals. The effects of sintering temperature on the microstructures and electrochemical performances of the as-synthesized samples were systematically investigated through XRD, SEM and electrochemical performance characterization. When sintered at 650°C, the obtained LiFe(MoO4)2 microcrystals show regular shape and uniform size distribution with mean size of 1–2 μm. At the lower temperature (600°C), the obtained LiFe(MoO4)2 microcrystals possess relative inferior crystallinity, irregular morphology and vague grain boundary. At the higher temperatures (680 and 700°C), the obtained LiFe(MoO4)2 microcrystals are larger and thicker particles. The electrochemical results demonstrate that the optimized LiFe(MoO4)2 microcrystals (650°C) can deliver a high discharge specific capacity of 925 mAh g−1 even at a current rate of 1 C (1,050 mA g−1) after 500 cycles. Our work can provide a good guidance for the controllable synthesis of other transition metal NASICON-type electrode materials.

“…In the first cathodic scan, a relatively strong reduction peak can be observed at around 0.46 V, which can be ascribed to the reduction reaction from nickel cobalt manganese corresponding metal oxide to their metal element along with the generation of Li 2 O during the discharge process. 43,44 And this reduction peak becomes wider in the subsequent cycle, which is a result of reduction reaction between Li and nickel cobalt manganese corresponding metal oxide. 45 In addition, a weak reduction peak is observed during the third cathodic scan because of the formation of the irreversible solid electrolyte interface (SEI film), and the corresponding potential is 0.15 V. [46][47][48] In the first anodic scan, an oxidation peak can be observed at around 2.0 V, which can be corresponded to the oxidation reaction of the elemental metals.…”

LiNi 1-x-y Co x Mn y O 2 lithium-ion battery, as the most installed battery of new energy vehicles, is facing the problem of large-scale scrap. In this paper, (Ni 0.1 Co 0.3 Mn 0.6 ) 3 O 4 anode material with a microsphere structure was successfully synthesized by carbonate coprecipitation method, which was obtained by recycling spent LiNi 0.6 Co 0.2 Mn 0.2 O 2 lithium-ion batteries through hydrometallurgy technology. This method eliminates the cumbersome separation steps, reduces the process cost, and realizes efficient recovery of valuable metals. The (Ni 0.1 Co 0.3 Mn 0.6 ) 3 O 4 anode material was characterized by inductively coupled plasma, X-ray photoelectron spectroscopy, X-ray diffraction analysis, scanning electron microscopy, and electrochemical measurements. The results show that (Ni 0.1 Co 0.3 Mn 0.6 ) 3 O 4 anode material has a microsphere structure with high crystallinity and exhibits a high discharge capacity (1575 mAhÁg −1 at 100 mAÁg −1 ) and a good cycling performance (659 mAhÁg −1 at 100 mAÁg −1 after 50 cycles). This work provides a new idea for the recycling of spent LiNi 1-x-y Co x Mn y O 2 batteries.
