“…Figure 4 displays the CV curves during various cycles. Apparently, the overlapping of the two characteristic peaks associated with Li ion insertion/extraction is related to limited lithium-ion diffusion at elevated scan rates [46]. Among the samples tested, TiN-LAMO_50_D showed the highest electrochemical surface area, as obtained from the various peaks.…”

“…LiAl 0.1 Mn 1.9 O 4 spinel oxide was synthesized via the combustion method described previously [46] where lithium nitrate anhydrous (LiNO 3 , 99%, Alfa Aesar, Kandel, Germany), manganese nitrate hydrate (Mn(NO 3 ) 2 •H 2 O, x~4-6, 98%, Aldrich, LSC, Athens, Greece) and aluminum nitrate (Al(NO 3 ) 3 •9H 2 O, 98-102%, Alfa Aesar, Kandel, Germany) served as oxidizer and urea (CO(NH 2 ) 2 , 99%, Aldrich, LSC, Athens, Greece) as fuel. The precursors were dissolved in deionized water and stirred at 200 • C, before being transferred in a muffle furnace preheated to 500 • C. The reaction took place immediately, yielding a foamy and voluminous powder.…”

“…Experimental methods for the physicochemical characterization of the synthesized materials and surfaces are described in detail in our previous works [14,46]. Powder X-ray diffraction (XRD; Bruker D8 Advance, Bruker, Birmingham, UK; Cu Ka radiation at 40 kV and 40 mA) was employed to identify the crystal structure of the electrodes.…”

“…Conventional experimental procedures were applied as described previously [19,46] to evaluate the electrochemical behavior of the as-prepared electrodes at ambient conditions. Briefly, two-electrode Swagelok-type cells were assembled in an argon-filled glove box with a water concentration lower than 1 ppm, using lithium metal foil as a reference and counter electrodes and a porous inert polymer membrane (SCIMAT MG 38111; Scimt Ltd., Swindon, United Kingdom) as the separator.…”

“…Both of these achievements resulted from the TiN coating layer. To obtain more insight into the active electrochemical surface area of the bare and surface-coated LiAl0.1Mn1.9O4 electrodes, cyclic voltammograms were collected in the potential range of 3.0-4.8 V. Generally, LiMn2O4 spinel materials show double oxidation and reduction peaks, which reflect the stepwise process of lithium ion insertion/extraction into the spinel structure [19,46,62]. Figure 4 displays the CV curves during various cycles.…”

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.

vehicles (HEVs), because of their high energy density and long lifetime. [1][2][3] In recent years, the ever-growing demand on electric vehicles contributes to the continuous growth of the battery market, and the energy storage devices of EVs/HEVs raise stern demands on higher energy density (>300 Wh kg −1 ) and lower cost (500 Wh kg −1 ), and the standard parameters for different electrode systems toward this high energy density goal are well summarized in the previous works. [7][8][9] In particular, the innovative battery chemistries (i.e., Li-metal battery and all-solid-state lithium battery) using Li metal as anode, exhibit much higher energy density than current lithium-ion batteries, whereas some technological issues are needed to be addressed first, such as dendrite formation suppression, industrial battery Current lithium-ion battery technology is approaching the theoretical energy density limitation, which is challenged by the increasing requirements of ever-growing energy storage market of electric vehicles, hybrid electric vehicles, and portable electronic devices. Although great progresses are made on tailoring the electrode materials from methodology to mechanism to meet the practical demands, sluggish mass transport, and charge transfer dynamics are the main bottlenecks when increasing the areal/volumetric loading multiple times to commercial level. Thus, this review presents the state-of-the-art developments on rational design of the commercialization-driven electrodes for lithium batteries. First, the basic guidance and challenges (such as electrode mechanical instability, sluggish charge diffusion, deteriorated performance, and safety concerns) on constructing the industry-required high mass loading electrodes toward commercialization are discussed. Second, the corresponding design strategies on cathode/anode electrode materials with high mass loading are proposed to overcome these challenges without compromising energy density and cycling durability, including electrode architecture, integrated configuration, interface engineering, mechanical compression, and Li metal protection. Finally, the future trends and perspectives on commercializationdriven electrodes are offered. These design principles and potential strategies are also promising to be applied in other...
