“…For instance, the ultrafast transport of Li + occurs in the 2D channel with a confined distance of 2l D for Li + during the charge-discharge process of a Li-battery. 58 In this review, we have systematically reviewed bioinspired 2D membranes for advanced energy devices. First, the classification and properties of 2D membranes are presented to justify their application in nanofluidic ion transport.…”

“…Thermal runaway can be triggered by mechanical abuse (e.g., crushing or penetration), chemical abuse (e.g., over-charging or short-circuiting), or thermal abuse (e.g., excessive external temperatures) [41], [42]. Ongoing research is trying to understand the mechanisms behind thermal runaway in order to propose suited solutions [43]. Feng et al (2018) discussed some of the thermal runaway mechanisms and proposed a protection concept for thermal runaway [44].…”

The purpose of this study is to look at both the potential and the limitations of first-generation electric aviation technology while emphasizing Norway's geographical opportunities and unique regional network. Electric flight distances up to 400 km would cover around 77 % of all flights within Norway. Currently, there is limited research into the suitability of battery-powered all-electric aviation in such scenarios, where Norway is an ideal case study location. In this work, the key factors, including battery technologies, propulsion systems, aircraft designs, and important aspects of the flight profile, are investigated to determine the suitability of specific routes in terms of the required power, energy, and battery size. A case study of five different flight distances in Norway (77 −392 km) and two different aircraft bodies (one retrofitted with an electric powertrain and one completely designed around the electric drivetrain) are presented. While the completely redesigned aircraft is observed to fulfill the power requirements of the routes, the results suggest that modest energy density improvements in batteries would facilitate retrofitting pre-existing aircraft. Finally, the study shows that it will be feasible to operate small (9 −39 passenger) electric aircraft on short-haul flights in Norway through either new aircraft designs or retrofitting shortly.

“…Nevertheless, the RSEI and Rct demonstrate a more considerable disparity between the two SOCs (0% SOC and 100% SOC). During the cycling test, the side-reaction both in graphite and SiO particles interface leads to the ever thickening-SEI film, especially in the cell with SiO/Gr anodes [25]. Thus, the ever-growing RSEI of the cell 20 wt.% SiO always shows a significantly smaller value at 0% SOC than it Similarly to the previous EIS test and analysis process, for the cell 20 wt.% SiO, the impedance spectra and model fitting data at the 1st, 100th, 200th, and 300th cycles are also tested and parametrically analyzed in detail.…”

Impedance Investigation of Silicon/Graphite Anode during Cycling

Silicon/graphite material is one of the most promising anodes for high-performance lithium-ion batteries. However, the considerable deformation occurring during the charge/discharge process leading to its degradation hinders its application. Research on the electrochemical performance of silicon/graphite anode have mainly focused on its cyclic performance and microscopic mechanism, whilst the correlation between electrochemical performance and the mechanical deformation of batteries at the cell level is in few numbers. In this study, the electrochemical performance and cycling performance of the cells in Ah-level silicon/graphite anode pouch cells with different SiO weight ratios (5 wt.%, 10 wt.%, and 20 wt.%) in the anode, and LiNi0.8Co0.1Mn0.1 as the cathode are investigated by quantitative analysis. It is found that cells with different SiO weight ratios in anodes under a different state of charge (SOC) and state of health (SOH) demonstrate remarkable differences in electrochemical impedance characteristics. The results show that SOC, SOH and the weight ratios of SiO are the main factors affecting the impedance characteristics for batteries with silicon/graphite anode, which is deeply related to the change in the thickness of the electrode during lithiation/delithiation. This research facilitates the application of EIS in battery management and the design of silicon/graphite anode lithium-ion batteries.
