“…Its thermal and electrochemical stability are low [13], and the costs of Ni, together with some geopolitical disagreements with one of its leading exporters (Indonesia) [14,15], make it recommendable to limit the content of Ni in the cathode material. On the other hand, spinel LiMn 2 O 4 (LMO) is a much cheaper material, based on an abundance of manganese, and it works at high voltage, which is positive for high-energy applications [16]. However, the main disadvantage of LMO is its low structural stability, which has its origin in the Jahn-Teller distortion [17] and manganese dissolution due to the 2Mn 3+ → Mn 4+ + Mn 2+ disproportionation reaction [16].…”

High-voltage spinel LiNi0.5Mn1.5O4 (LNMO) is a promising candidate as a lithium-ion battery cathode material to fulfill the high-energy density demands of the electric vehicle industry. In this work, the design of the experiment’s methodology has been used to analyze the influence of the ratio of the different components in the electrode preparation feasibility of laboratory-scale coatings and their electrochemical response. Different outputs were defined to evaluate the formulations studied, and Derringer–Suich’s methodology was applied to obtain an equation that is usable to predict the desirability of the electrodes depending on the selected formulation. Afterward, Solver’s method was used to figure out the formulation that provides the highest desirability. This formulation was validated at a laboratory scale and upscaled to a semi-industrial coating line. High-voltage 1 Ah lithium-ion pouch cells were assembled with LNMO cathodes and graphite-based anodes and subjected to rate-capability tests and galvanostatic cycling. 1 C was determined as the highest C-rate usable with these cells, and 321 and 181 cycles above 80% SOH were obtained in galvanostatic cycling tests performed at 0.5 C and 1 C, respectively. Furthermore, it was observed that the LNMO cathode required an activation period to become fully electrochemically active, which was shorter when cycled at a lower C-rate.

“…In addition, the preparation processes of morphology control strategies such as constructing nanostructures and designing specific exposed crystal facets are complex and have low repeatability, making it challenging to achieve large-scale production and commercialization. In contrast, element doping could suppress Jahn–Teller distortion and enhance the structural stability of spinel LiMn 2 O 4 , thereby improving the cycling performance. − For example, Goodenough et al proposed that Li + ions dope into the Mn octahedral 16 d sites of spinel LiMn 2 O 4 , efficiently suppressing the ordering of Li + ions and enhancing the stability of the spinel structure. Later, Liu et al fabricated Li + -doped spinel LiMn 2 O 4 to realize Li/Mn disorder and surface reconstruction, partly disrupting the symmetry of the spinel structure and enhancing the strength of Mn–O bonds.…”

Low-cost and e cient electrode materials play a key role in improving the performance of Lithium Ion Battery. In this paper, the single-crystalline LiMn 2 O 4 nanoparticles were synthesized through the gelcombustion method assisted by microwave followed by calcination treatment. High-quality singlecrystallinity characteristics of the LiMn 2 O 4 precursors powder could be well retained after a hightemperature (990℃) solid-state reaction. When valued as the working electrode materials for Lithium Ion Battery, they presented the exceptional electrochemical performances including the high speci c capacity for initial discharge of 120.53mAh/g, the good rate capability with the retention of 65.52% at 5C of the capacity at 0.2C, and better cyclic performance with a capacity retention ratio of 90.01% after 300 cycles.The outstanding electrochemical performance of our prepared single-crystalline LiMn 2 O 4 nanoparticles was perceived as the hopeful electrode materials for high-power Lithium Ion Battery.
