“…For example, an unannealed nano-crystalline Li x Mn 2−y O 4 (n-LMO) cathode film could have a capacity comparable to a c-LMO film between 4.5 and 2.5 V and a long cycle life in spite of its limited rate capability due to its low electrical conductivity and large interface resistance.

As the world steps into the era of Internet of Things (IoT), numerous miniaturized electronic devices requiring autonomous micropower sources will be connected to the internet. All‐solid‐state thin‐film lithium/lithium‐ion microbatteries (TFBs) combining solid‐state battery architecture and thin‐film manufacturing are regarded as ideal on‐chip power sources for IoT‐enabled microelectronic devices. However, unlike commercialized lithium‐ion batteries, TFBs are still in the immature state, and new advances in materials, manufacturing, and structure are required to improve their performance. In this review, the current status and existing challenges of TFBs for practical application in internet‐connected devices for the IoT are discussed. Recent progress in thin‐film deposition, electrode and electrolyte materials, interface modification, and 3D architecture design is comprehensively summarized and discussed, with emphasis on state‐of‐the‐art strategies to improve the areal capacity and cycling stability of TFBs. Moreover, to be suitable power sources for IoT devices, the design of next‐generation TFBs should consider multiple functionalities, including wide working temperature range, good flexibility, high transparency, and integration with energy‐harvesting systems. Perspectives on designing practically accessible TFBs are provided, which may guide the future development of reliable power sources for IoT devices.

“…Also, imposing t r could contribute to a higher crystallinity and lower residual stress of the synthesized Li x MnO 2 through triggering the recrystallization of electrodeposit as a result of Ostwald ripening. , Moreover, imposing t c immediately after t r could make a predominant difference in the electrodeposition mechanism through interfering with the growth mechanism of Li x MnO 2 crystallites and grain boundaries, which may lead to the exclusive and unique morphologies. Thereof, a partial stripping of the deposit during t c provides the possibility of constructing exclusive morphologies of Li x MnO 2 with controlled porosity by modulating the values of t c imposed on the anode. ,, Hypothetically, exerting a given value of t c on the anode would stimulate the migration of lithium ions toward the working electrode with negative polarization, leading to higher Li + contents in Li x MnO 2 samples. , Comparison of the Li + contents of LMO-R samples (summarized in Table ) to those of LMO samples synthesized using pulse current electrodeposition reported in our previous work has definitely evidenced this assumption. The mechanism of Li x MnO 2 electrodeposition using PRED is schematically illustrated in Scheme .…”

“…24 Lee et al obtained fine nanorod morphology of Mn 2 O 3 with a high electrical conductivity via the PRED synthesis technique from manganese acetate precursor, which renders the excellent capacity of 448 F g −1 at 10 mV s −1 . 15 Herein, pursuing our previous work, 25,26 we have demonstrated how pulse reverse current could be navigated to achieve hierarchical and mesoporous α/γ-LiMnO 2 nano/microstructures with tuned chemical composition and superior electrochemical performance as a cathode material of Li-ion battery. To the best of our knowledge, although previous works have proved PRED as a highly susceptible method to obtain functional nanostructures with unique properties, there is no research work investigating this method to achieve engineered active materials of Li-ion batteries with a great potential of controlling the electrochemical properties through controlled modulation of PRED parameters.…”

Given the ever-growing demand of electric vehicles and renewable energies, addressing the poor cyclic stability of lithium manganese dioxide is an urgent challenge. In this study, pulse reverse current as the driving force of a one-pot anodic electrodeposition was exploited to design the physicochemical and electrochemical characteristics of lithium manganese dioxides as cathode materials of Li-ion battery. The pulse reverse parameters, including the span of anodic and cathodic current application (t a and t c) and frequency (f′), were systematically modulated to determine the optimized values through monitoring the physicochemical properties using X-ray diffraction, thermogravimetric analysis/differential scanning calorimetry, field emission scanning electron microscopy, transmission electron microscopy, energy-dispersive spectrometry, Raman spectroscopy, N2 adsorption–desorption isotherms, and inductively coupled plasma-optical emission spectroscopy, as well as the electrochemical properties using cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic charge–discharge at different currents. Based on the results, Li0.65MnO2 synthesized using t a = 95 ms, t c = 5 ms, and f′ = 8.33 Hz at the constant magnitude of anodic peak current density of 1 mA dm–2 was determined as the optimized sample. The optimized lithium manganese dioxide rendered superior electrochemical performance with the initial discharge capacity of 283 mAh g–1, which accounts for 96.4% of the theoretical discharge capacity, preserving 88.3% of this capacity after 300 cycles at 0.1 C and, in the meantime, was able to release a discharge capacity of 115 mAh g–1 even after cycling at a higher current of 10 C. The superior electrochemical behavior of Li0.65MnO2 was attributed to the exclusive hierarchical urchin-like morphology as well as mesoporous nano/microstructures having a notably high Brunauer–Emmett–Teller surface area of 320.12 m2 g–1 alongside mixed-phase α/γ structure owing to the larger 2 × 2 tunnels, which offer more facile Li+ diffusion.

Lithium manganese oxides are considered as promising cathodes for lithium‐ion batteries due to their low cost and available resources. Layered LiMnO2 with orthorhombic or monoclinic structure has attracted tremendous interest thanks to its ultrahigh theoretical capacity (285 mAh g−1) that almost doubles that of commercialized spinel LiMn2O4 (148 mAh g−1). However, LiMnO2 undergoes phase transition to spinel upon cycling cause by the Jahn‐Teller effect of the high‐spin Mn3+. In addition, soluble Mn2+ generates from the disproportionation of Mn3+ and oxygen release during electrochemical processes may cause poor cycle performance. To address the critical issues, tremendous efforts have been made. This paper provides a general review of layered LiMnO2 materials including their crystal structures, synthesis methods, structural/elemental modifications, and electrochemical performance. In brief, first the crystal structures of LiMnO2 and synthetic methods have been summarized. Subsequently, modification strategies for improving electrochemical performance are comprehensively reviewed, including element doping to suppress its phase transition, surface coating to resist manganese dissolution into the electrolyte and impede surface reactions, designing LiMnO2 composites to improve electronic conductivity and Li+ diffusion, and finding compatible electrolytes to enhance safety. At last, future efforts on the research frontier and practical application of LiMnO2 have been discussed.
