“…Therefore, ARLBs have received wide interest especially in recent years [15 -26]. However, the traditional micrometer-sized materials do not show good electrochemical performance in an aqueous electrolyte [18]. where x is 0, 0.05 and 0.10, respectively, were dissolved in distilled water and mixed with an aqueous solution of citric acid.…”

Ni-doped spinel LiNixMn2-xO4 (x = 0, 0.05, 0.10) samples were prepared by a sol-gel method. Structure and morphology of the samples were characterized by X-ray diffraction, scanning electron microscopy, BrunnauerEmmet-Teller method and inductively coupled plasma atomic absorption spectrometry. The electrochemical behavior as a cathode material (positive mass) for aqueous rechargeable lithium batteries (ARLBs) was investigated by cyclic voltammetry, electrochemical impedance spectroscopy, capacity measurements and cycling tests. The results show that the LiNi 0.1Mn1.9O4 electrode presents the best rate and cycling performance but low reversible capacity. In contrast, the LiNi 0.05Mn1.95O4 electrode shows a higher reversible capacity and relatively good cycling behavior. At a current density of 150 mA g-1, LiNi0.05Mn1.95O4 delivers a reversible capacity of 102 mA h g-1. At the relative high current densities of 1500 and 3000 mA g-1, the LiNi 0.05Mn1.95O4 electrode still delivers reversible capacities of 95.0 and 88.7 mA h g-1, respectively. The Ni-doped samples show excellent cycling life in 0.5 mol L-1 Li 2SO4 aqueous solution. The capacity retention ratios for LiNi0.05Mn1.95O4 and LiNi0.10Mn 1.90O4 after 800 cycles at a current density of 1500 mA g-1 are 79.4% and 91.1%, respectively, much higher than that for the undoped LiMn2O4 at only 37.8%. 2013 Elsevier Ltd. 2013 Elsevier Ltd.

“…Some [78][79][80] first synthesized a precursor, then reacted it with other raw materials to obtain the target product. Some [62,81] mixed all the raw materials at once and then reacted them together. The differences of the process may influence the morphology, particle size, and therefore the electrochemical performance to a great extent [80].…”

“…Solid state reactions [60][61][62][63] dope the atom in the lattice of the main structure, but all the products remain in the standard spinel structure. The products, for example, the reported Li(Mn 2−x Co x )O 4 (0 ≤ x ≤ 0.5) [64] [66] just had small cell parameter changes in the lattice, and these were good for the stability of the structure and the improvement of the cycle life.…”

Spinel LiMn 2 O 4 is an appealing candidate cathode material for Li-ion rechargeable batteries, but it suffers from severe capacity fading, especially at higher temperature (55 °C) during discharging/charging. In recent years, many attempts have been made to synthesize modified LiMn 2 O 4 . This paper reviews the recent research on the preparation and doping modes of doped LiMn 2 O 4 for modifying the LiMn 2 O 4. We firstly compared preparation methods for doped spinel LiMn 2 O 4 , such as solid state reactions and solution synthetic methods. Then we mainly discuss doping modes reported in recent years, such as bulk doping, surface doping and combined doping. A comparison of different doping modes is also provided. The research shows that the multiple-ion doping and combined doping modes of LiMn 2 O 4 used in Li-ion battery are excellent for improving different aspects of the electrochemical performance which holds great promise in the future. From this paper, we also can see that spinel LiMnO 4 as an attractive candidate cathode material for Li-ion batteries.

“…Yuan et al [154] synthesized a series of Al-doped LiAlxMn2−xO4 materials by solid-phase grinding reaction at room temperature and calcining at different temperatures for different durations subsequently. Electrochemical experiments demonstrated that the cyclability of the LiMn2O4 (LMO) spinel doping with an appropriate amount of Al was better than the pristine LMO in an aqueous media.…”

There has been increasing interest in developing micro/nanostructured aluminum-based materials for sustainable, dependable and high-efficiency electrochemical energy storage. This review chiefly discusses the aluminum-based electrode materials mainly including Al2O3, AlF3, AlPO4, Al(OH)3, as well as the composites (carbons, silicons, metals and transition metal oxides) for lithium-ion batteries, the development of aluminum-ion batteries, and nickel-metal hydride alkaline secondary batteries, which summarizes the methodologies, related charge-storage mechanisms, the relationship between nanostructures and electrochemical properties found in recent years, latest research achievements and their potential applications. In addition, we raise the relevant challenges in recently developed electrode materials and put forward new ideas for further development of micro/nanostructured aluminum-based materials in advanced battery systems.
