“…Due to oxygen’s high potential property, oxygen from cathode is highly oxidative and the reduction of oxygen forms a free oxygen radical in the electrolyte as shown in Figure . , These oxygen radicals yield a byproduct such as H 2 O and CO 2 . The existence of H 2 O can lead to the production of impurities of Li 2 O or by diffusion of Li and O from the cathode and affects electrochemical performances by producing LiF. , In terms of CO 2 , it reacts with Li 2 O to form Li 2 CO 3 . And Li 2 CO 3 along with LiF can form a SEI layer coated on the surface on the particle, which decreases the conductivity …”

High voltage spinel LiMn1.5Ni0.5O4 (LMNO) is a promising energy storage material for the next generation lithium batteries with high energy densities. However, due to the major controversies in synthesis, structure, and interfacial properties of LMNO, its unsatisfactory performance is still a challenge hindering the technology’s practical applications. Herein, this paper provides general characteristics of LiMn1.5Ni0.5O4 such as spinel structure, electrochemical properties, and phase transition. In addition, factors such as electrolyte decomposition and morphology of LMNO that influence the electrochemical performances of LMNO are introduced. The strategies that enhance the electrochemical performances including coating, doping, electrolytes, and oxygen deficiency are comprehensively discussed. Through the discussion of the present research status and presentation of our perspectives on future development, we provide the rational design of LMNO in realizing lithium-ion batteries with improved electrochemical performances.

“…The Author(s). Published by CBIORE However, LNMO has many challenges, particularly for applications with high-power requirements, such as low cycle performance when applying high current rates (Fakhrudin et al, 2021;Sudaryanto et al, 2021). The primary issue with LNMO is the occurrence of degradation reactions in high-voltage operation that potentially cause corrosion reactions in the interface region between the cathode and electrolyte, resulting in low rate stability, especially at high temperatures (Ghosh et al, 2021;Yi et al, 2016).…”

In order to fulfill the demand for high energy and capacity, an electrode with high-voltage capability, namely LiNi0.5Mn1.5O4 (LNMO) that has an operating potential of up to 4.7 V vs Li/Li+, is currently becoming popular in Li-ion battery chemistries. This research produced LNMO by using a solid-state method with only one-step synthesis route to compare its electrochemical performance with different lithium sources, including hydroxide (LNMO-LiOH), acetate (LNMO-LiAce), and carbonate (LNMO-LiCar) precursors. TGA/DSC was first performed for all three sample precursors to ensure the optimal calcination temperature, while XRD and SEM characterized the physical properties. The electrochemical measurements, including cyclic voltammetry and charge-discharge, were conducted in the half-cell configurations of LNMO//Li-metal using a standard 1 M LiPF6 electrolyte. LNMO-LiOH samples exhibited the highest purity and the smallest particle size, with values of 93.3% and 418 nm, respectively. In contrast, samples with higher impurities, such as LNMO-LiCar, mainly in the form of LixNi1-xO (LiNiO), displayed the largest particle size. The highest working voltage possessed by LNMO-LiOH samples was 4.735 V vs Li/Li+. The results showed that LNMO samples with LiNiO impurities would affect the reaction behavior that occurs at the cathode-electrolyte interface during the release of lithium-ions, resulting in high resistance at the battery operations and decreasing the specific capacity of the LNMO during discharging. The highest value, shown by LNMO-LiOH, was up to 92.75 mAh/g. On the other side, LNMO-LiCar only possessed a specific capacity of 44.57 mAh/g, indicating a significant impact of different lithium sources in the overall performances of LNMO cathode.
