“…Ionics has been traditionally used for long-standing energy applications, 1,2 i.e., ion batteries which rely on the ionic motion of either Li or Na; [3][4][5][6][7][8][9][10] solid oxide fuel cells based on the ionic motion of either oxygen or hydrogen; [11][12][13][14] and catalysts which use oxidation and reduction processes of O 2 or CO 2 , [15][16][17] and so on. In these applications, compared with electronic motion, ionic motion is essentially very slow, 18 resulting in many unsolved challenges.…”

This review provides the design principles to develop new nanoionic applications using vertically aligned nanostructured (VAN) thin films, incorporating two phases which self-assemble in one film. Tunable nanoionics has attracted great attention for energy and device applications, such as ion batteries, solid oxide fuel cells, catalysts, memories, and neuromorphic devices. Among many proposed device architectures, VAN films have strong potential for nanoionic applications since they show enhanced ionic conductivity and tunability. Here, we will review the recent progress on state-of-the-art nanoionic applications, which have been realized by using VAN films. In many VAN systems made by the inclusion of an oxygen ionic insulator, it is found that ions flow through the vertical heterointerfaces. The observation is consistent with structural incompatibility at the vertical heteroepitaxial interfaces resulting in oxygen deficiency in one of the phases and hence to oxygen ion conducting pathways. In other VAN systems where one of the phases is an ionic conductor, ions flow much faster within the ionic conducting phase than within the corresponding plain film. The improved ionic conduction coincides with much improved crystallinity in the ionically conducting nanocolumnar phase, induced by use of the VAN structure. Furthermore, for both cases Joule heating effects induced by localized ionic current flow also play a role for enhanced ionic conductivity. Nanocolumn stoichiometry and strain are other important parameters for tuning ionic conductivity in VAN films. Finally, double-layered VAN film architectures are discussed from the perspective of stabilizing VAN structures which would be less stable and hence less perfect when grown on standard substrates.

“…In other words for each battery to be included in simulations using the proposed model, two or more measurements on that battery have to be done to determine the value of α. It should also be noted that the value of α is likely to be dependent on the degradation (or ageing) of the battery, because the over-all performance of the battery decreases over time [10]. However, the influence of the battery degradation on the value of α has not been investigated.…”

Abstract-In this paper the relatively simple model for State of Charge prediction, based on energy conservation, introduced in [1] is improved and verified. The model as introduced in [1] is verified for Pb-acid, Li-ion and Seasalt batteries. The model is further improved to accommodate the rate capacity effect and the capacity recovery effect, the improvements are verified with lead-acid batteries. For further verification the model is applied on a realistic situation and compared to measurements on the behavior of a real battery in that situation. Furthermore the results are compared to results of the well-established KiBaM model. Predictions on the SoC over time done using the proposed model closely follow the SoC over time calculated from measured data. The resulting improved model is both simple and effective, making it specially useful as part of smart control, and energy usage simulations.

“…With the use of these novel SSEs, the developed Li-S batteries can operate at higher current densities with improved cycle life at room temperature. On the other hand, it should be pointed out that these developed sulfide electrolytes are not chemically and electrochemically stable, triggering serious side reactions and increased resistance at the interfaces of cathode and anode materials [375]. To overcome the challenges of the interface between electrolyte and electrode materials, many novel nanostructured materials have been utilized.…”

Lithium-sulfur (Li-S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li-S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li-S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li-S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li-S publications to find the shortcomings of Li-S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li-S batteries are discussed.
