Diffraction peaks at 18.5, 35, 43.5, 57, and 63.3° correspond to the (111), (311), (400), (333), and (440) reflections of the LTO phase, respectively . The XRD patterns of the LNSB_H3 and LNSB_L3 samples showed similar peak intensities because the same amounts of lithium and titanium precursors were used.…”

Nowadays, thickness optimization of an electrode is considered an effective approach to achieve a high energy density or high areal capacity of Li-ion batteries. In this paper, we report a simple electrospinning technique to develop free-standing sheet bundles of lithium titanium oxide (LTO) nanowires with a readily controlled thickness of electrodes. The LTO nanowire sheet bundles (LNSBs) can show a very high areal capacity as an anode due to its microscale layer-by-layer configuration in which the nanoscale LTO nanowires are networked in each microscale layer. Such unique structures with interspaces formed between the multiple stacked sheet layers should promote electrolytes to efficiently penetrate through the thick electrode layer. Nanoscale wire assemblies can also increase the transfer rates of ions and electrons during the lithiation/delithiation processes. Consequently, the fabricated LNSB electrode delivers an ultrahigh areal capacity of up to ca. 14.2 mA h cm–2 for the first cycle and ca. 6.5 mA h cm–2 for the 500th cycle at 0.2C rate current density, which is a much larger areal capacity than the commercial graphite anode (ca. 3.5 mA h cm–2). Such a high areal discharge capacity on a novel free-standing electrode design could provide an idea for advanced energy storage applications.

“…LTO is well-known for its low reactivity with common electrolytes, intense volume changes, and high voltage plateau of 1.55 V (vs Li/Li + ). [141][142][143] The effect of calendering on the LTO anode has been investigated. For example, Acharya et al [144] investigated the influence of calendering on the charging rate of LTO electrode anodes.…”

As the demand for lithium‐ion batteries (LIBs) continuously grows, the necessity to improve their efficiency/performance also grows. For this reason, optimization of the individual production steps is critical. Calendering is a crucial production step whereby electrode coatings are compacted to targeted densities. This process affects the porosity, adhesion, thickness, wettability, and charge transport properties of the electrodes, as well as the homogeneity of the coatings. Optimal calendered electrodes improve volumetric energy density, cyclic stability, and rate capability of the cells and also enhance the structural stability of the active material, which affects electrode safety and polarization. This article outlines the fundamental processes and mechanisms, as well as how modeling, simulation, and tomography can be used to optimize these processes. Additionally, the influence of calendering on a wide range of anode and cathode active materials is discussed. This review serves to give a deeper understanding into the calendering process‐structure‐performance relationships, and how they can be optimized to improve the performance of LIBs.

“…Today, the anode materials for lithium-ion batteries usually use embedded electrodes and alloy electrodes [8][9][10][11][12]. As a typical embedded electrode material, carbon has the advantages of low cost and wide source, but during the charging and discharging process, carbon materials are prone to structural collapse, resulting in reduced capacity and shortened service life [12][13][14][15][16] . In contrast, alloy-type electrodes, represented by silicon, tin and titanium, achieve energy storage through alloying reactions with lithium ions [11,12,[17][18][19][20].…”

In recent years, the development and use of new energy sources has become a popular attraction. However, environmentally friendly energy sources such as wind, solar and tidal energy cannot meet the need for a stable energy supply. Therefore, reliable and efficient energy storage systems have received wide attention. Lithium-ion batteries store significant energy per unit volume through electrochemical reactions. Supercapacitors achieve a rapid storage and release of energy by a double electric layer. As a combination of lithium-ion battery and supercapacitor, lithium-ion capacitor has the characteristics of both high specific power and high specific energy, which can complete energy storage and release energy stably with high efficiency. This article introduces the structure of lithium-ion capacitors, including electrode materials, electrolyte and separator. In addition, the common types of electrode materials and the latest research progress are highlighted.
