“…However, the resulting improvements are usually at the expense of capacity and thus far from satisfactory . A reduction of the size of LiNi 0.5 Mn 1.5 O 4 particles is an effective way to enhance the electron and Li‐ion transport . On one hand, nanoparticles can provide a shorter distance for electron exchange at the electrode–electrolyte interface and thus improve both the rate capability and the cycle stability.…”

Synthesis of Well‐Crystallized, High‐Performance LiNi_0.5Mn_1.5O₄ Octahedra as Lithium‐Ion‐Battery Electrode Promoted by Metal Manganese Powders

et al. 2016

Metal Mn powders instead of conventional Mn salts were used for the first time tried as a Mn source to synthesize high‐performance LiNi0.5Mn1.5O4 (M‐LNMO) using a sol–gel method. Mn powders promote the formation of well‐crystallized octahedra with the Fd3m spinel structure. M‐LNMO has a lower stress, a slightly smaller lattice constant, which arises from the lower amount of Mn3+ because of the lower oxygen deficiency, a higher cation ordering, and longer Li−O and shorter Mn (Ni)−O bonds than LiNi0.5Mn1.5O4 synthesized from manganese acetate (MA‐LNMO). The well‐crystallized octahedra, the low stress, the low amount of Mn3+, and the long Li−O and short Mn (Ni)−O bonds for M‐LNMO result in its excellent performance such as a discharge capacity of 68 mAh g−1 at 50 C and a capacity retention of 90 % after 600 cycles at 10 C. This study raises the possibility to promote the synthesis of high‐performance LiNi0.5Mn1.5O4 for mass production by using cheap and simple Mn sources such as Mn powders.

“…However, pure spinel phase LiNi 0.5 Mn 1.5 O 4 is difficult to synthesize because impurity such as Li x Ni 1x O usually forms due to oxygen loss reaction at high synthetic temperatures, resulting in capacity fade [265,266]. Jin and Duh [267] synthesized pure LiNi 0.5 Mn 1.5 O 4 with the help of polymer surfactant in a nonaqueous route.…”

Lithium ion batteries (LIBs) represent one of the most promising solutions for environmentally friendly transportation such as electric vehicles. The demand for high energy density, low cost and environmentally friendly batteries makes high-capacity cathode materials very attractive for future LIBs. Layered LiNi x Co y Mn z O 2 (x+y+z=1), Li-rich oxides and Li-V-O compounds have attracted much attention due to their high capacities in recent years. In this review, we focus on the state-of-the-art research activities related to LiNi x Co y Mn z O 2 , Li-rich oxides and Li-V-O compounds, including their structures, reaction mechanisms during cycling, challenges and strategies that have been studied to improve their electrochemical performances. layered LiNi x Co y Mn z O 2 , Li-rich layered oxide, Li-V-O compound, cathode material, Li-ion battery Citation: Zhang Y D, Li Y, Xia X H, et al.

“…Recently, natural biomaterials such as cotton, , bagasse, corn stalk, protein, yeast, , pollen, and legume each have been used as a biotemplate to synthesis of biomorphic functional materials. These natural species present highly optimized, unique material systems after stringent natural selection processes of billions of years. , By elaborately replicating these structural systems, we can obtain biomorphic functional materials with a subtle micronanostructure, which are barely attainable by traditional synthesized strategies. , With their unique structural advantages, these novel biomorphic materials are, therefore, expected to demonstrate amazing applicable properties. − To date, 1D micro-/nanostructured tubular ZnO, NiO, SiO 2 , and Al 2 O 3 have been successfully synthesized through the use of different biomaterials, and their performances have been quite intriguing in gas adsorption and energy storage/conversion applications.…”

ZnMn2O4 microtubules (ZMO-MTs) with a mesoporous structure are fabricated by a novel yet effective biomorphic approach employing cotton fiber as a biotemplate. The fabricated ZMO-MT has approximately an inner diameter of 8.5 μm and wall thickness of 1.5 μm. Further, the sample of ZMO-MT displays a large specific surface area of 48.5 m2 g–1. When evaluated as a negative material for Li-ion batteries, ZMO-MT demonstrates an improved cyclic performance with discharge capacities of 750.4 and 535.2 mA h g–1 after 300 cycles, under current densities of 200 and 500 mA g–1, respectively. Meanwhile, ZMO-MT exhibits superior rate performances with high reversible discharge capacities of 614.7 and 465.2 mA h g–1 under high rates of 1000 and 2000 mA g–1, respectively. In sodium ion batteries applications, ZMO-MT delivers excellent high discharge capacities of 102 and 71.4 mA h g–1 after 300 cycles under 100 and 200 mA g–1, respectively. An excellent rate capability of 58.2 mA h g–1 under the current density of 2000 mA g–1 can also be achieved. The promising cycling performance and rate capability could be benefited from the unique one-dimensional mesoporous microtubular architecture of ZMO-MT, which offers a large electrolyte/electrode accessible contact area and short diffusion distance for both of ions and electrons, buffering the volume variation originated from the repeated ion intercalation/deintercalation processes.
