“…LNMO has some similarities with LMO in structure and performance, such as the capacity attenuation. The main reasons for the capacity degradation of LMO and LNMO are oxygen defects, [32] electrolyte decomposition caused by high pressure, [33] dissolution of Mn [14,34] and the Jahn‐Teller effect of Mn 3+ [35] …”

“…For LMO, the structure changes due to the Jahn‐Teller effect of Mn 3+ during the cycle, which changes the crystal structure from a cubic phase to a tetragonal phase [13a] . In addition, part of the phase transition caused by the Jahn‐Teller effect is irreversible, and the volume effect aroused by the phase transition even cracks the cathode particles during cycling, and further lead to the dissolution of Mn, which leads to the deterioration of cycle performance [14] . Jahn‐Teller distortion can increase the reactivity of LIBs with acids and the dissolution of TM ions in two ways: first, it puts an electron into the dz 21 orbital, and the electron is delocalized on the TM and O atoms; second, compared with the equivalence oxygen, the Lewis base strength of the axial oxygen is improved [35] .…”

Lithium‐ion batteries (LIBs) are currently widely applied in many aspects of life, but with the development, the capacity of lithium‐ion batteries can no longer meet the needs. One of the dominant factors to restricting the capacity of LIBs is the cathode materials. Among the derivatives of spinel cathode LiMn2O4 (LMO), LiNi0.5Mn1.5O4 (LNMO) has become one of the research promising cathode materials in the current LIBs due to its high working voltage (4.7 V) and large theoretical specific capacity (147 mAh g−1). However, the short cycle life of LNMO during the electrochemical process limits its large‐scale commercial applications. Thus, it is necessary to summarize and discuss the recent development of LNMO. Through comparison with LiMn2O4, the structure, electrochemical properties of LNMO, influence of Mn on the performance of LNMO, and the capacity fading mechanism are analyzed and discussed in detail. We also summarize the modification methods of LNMO and the influence of preparation methods on the structure and performance of LNMO. Finally, some prospects of LNMO cathode are put forward. This Review article can provide helpful references for future design and construction of LNMO.

“…In order to suppress the Jahn-Teller distortion and ensure the structural integrity of the electrode, many researchers have proposed replacing the small amount of trivalent manganese ions in the octahedral sites with several metal cations [11][12][13]. Following the same strategy, we recently studied combustion-synthesized Li x Mn 2 O 4 nanostructures effectively doped with aluminium ions that minimized capacity fading and resulted in enhanced electrochemical performance, especially in comparison with undoped samples [14].…”

“…Based on previous work where the successful Al doping of spinel LiMn 2 O 4 minimized capacity fading [14], we take a step forward in this study to report on the modification of the cathode surface LiAl 0.1 Mn 1.9 O 4 with a titanium nitride (TiN) coating layer via magnetron sputtering. Magnetron sputtering is a functional technique in which thin films can easily be obtained by carefully controlling the desired porosity and thickness.…”

The present work addresses the issues related to the capacity fading of spinel LiMn2O4, such as Mn leaching and Jahn–Teller distortion and suggests an advanced TiN-coated LiAl0.1Mn1.9O4 (LAMO) cathode material as an electrode for lithium-ion batteries. TiN coating layers with the same thickness but a different porosity cover the LiAl0.1Mn1.9O4 electrode via reactive magnetron sputtering, and present promising electrochemical behavior. In contrast with the pristine LiAl0.1Mn1.9O4, the dense TiN-coated LiAl0.1Mn1.9O4 electrode demonstrates a remarkable long-term cycling by reducing the contact area of the electrode/electrolyte interface, resulting in structure stabilization.

Spinel LiMn2O4 is one of the most important cathode materials but it still suffers from rapid capacity degradation during electrochemical cycling. Beside surface coating to improve the electrochemical performances, controlling the bulk morphology of LiMn2O4 (LMO) is another effective strategy. In this work, porous LiMn2O4 microspheres composed of numerous primary nanoparticles are synthesized by micro‐emulsion and co‐precipitation methods. The porous structure and the primary nanoparticles size of LiMn2O4 are effected by the concentration of micro‐emulsion and the precursor of Mn2+. The well‐established porous LiMn2O4 microspheres with abundant ionic channels and good contact with electrolyte endow the spinel a remarkable electrochemical performance. After 300 cycles, 0.50 M‐LMO sample presents excellent reversible capacity of 112.8 mAh g−1 at 0.5 C rate. After 1000 cycles, 0.50 M‐LMO sample presents the highest capacity of 97.9 mAh g−1 and remains 54.2 mAh g−1 at the current rate of 10 C. The porous spherical structure of cathode materials is essential to improve the rate performance due to the good contact between the active material and electrolyte.
