Topic Information

Dear Colleagues,

As the world faces the daunting combination of surging energy demands, rising greenhouse gas emissions and tightening energy resources, renewable power is growing impressively to fulfil the ever-increasing power demands of newly emerging applications. However, the utilization of energy in the form of electricity generated from renewable resources to satisfy a strong rebound in global electricity demand can only be addressed by a step change in energy storage. This signifies that energy storage is more important now than ever, and the continuously developing demands of contemporary applications necessitate the design of adaptable energy storage/conversion and power supply systems offering wide ranges of energy and power densities. Since no single energy storage technology can address such energy/power requirements simultaneously, various combinations of storage technologies and systems can be developed. In this regard, batteries, electrochemical capacitors (ECs) and fuel cells, three crucially important electrochemical energy storage/conversion devices, will play a vital role in producing sufficient renewable energy to meet our future energy demands. Yet, the inherent intermittency of supply from renewable energy resources can only be addressed by a step change in the energy storage/conversion capability of these devices to ensure security and continuity of energy supply from a more distributed and intermittent supply base. This Special Issue seeks to contribute to an agenda encompassing all aspects of energy storage/conversion in batteries, electrochemical capacitors (ECs) and fuel cells and their combinations through enhanced scientific and multi-disciplinary works, aiming to improve the current knowledge and performance of energy storage/conversion systems and their combinations for a wide range of energy and power supplies.

We are particularly interested in articles and reviews that explore all features of batteries, electrochemical capacitors (ECs) and fuel cells, their energy storage/conversion mechanisms and electric components. We also encourage papers presenting processes and implementations in this field while addressing the currently existing challenges associated with their electrode and electolyte materials, structural design and optimization, application of novel materials, current trends and future developments, including both electrochemical as well as electrical engineering aspects and fabrication of their components and production of the device. Moreover, their performance analysis, operational management and integration to improve the overall performance of energy /power supply systems with their associated advances and challenges are also of special interest.

Topics of interest for publication include, but are not limited to, the following:

  • Technologies, processes and materials.
  • Synthesis, characterization and properties of the electrode materials.
  • Novel and benign electrolytes for batteries and electrochemical capacitors and the type of electrolytes used in fuel cells.
  • Understanding of their underlying mechanisms of energy storage/conversion.
  • Structural design and optimization, and application of novel materials.
  • Experimental techniques for testing, characterization, monitoring and diagnosis.
  • Modeling and experimental validation of the device.
  • Reliability and safety.
  • Sizing and optimization algorithms.
  • Performance analysis and operational management of the device under different conditions.
  • Their technoeconomic analysis and market analyses. 
  • Their integration with other storage technologies to improve the overall performance of energy systems.

Coffee, as one of the most traded resources, generates a vast amount of biogenic by-products. Coffee silver skins (CSS), a side stream from the roasting process, account for about 4 wt.%. Despite the abundancy of CSS, possible routes to generate added value for broad applications are limited. Herein, we present an approach to use CSS as a precursor material for supercapacitor electrodes. KOH activated carbon (AC) was produced from CSS. The resulting AC—CSS was characterized by X-ray diffraction, gas sorption analysis, scanning electron microscopy, and Raman spectroscopy. The highly porous AC—CSS exposes a specific surface area of more than 2500 m2 g−1. Electrodes formed with AC—CSS were electrochemically characterized by performing cyclic voltammetry and galvanostatic cycling. The electrodes were further assembled into a supercapacitor device and operated using 1 M sulfuric acid as electrolyte. In addition, various quinones were added to the electrolyte and their impact on the capacitance of AC—CSS electrodes was analyzed. In this work, we were able to show that CSS are a valuable source for supercapacitor applications and that coffee-waste-derived quinones can act as capacitance enhancers. Thus, the findings of this research show a valuable path towards sustainable and green energy storage solutions. Full article

This paper focuses on the development of a model-based train performance simulation with the practical train operation data using MATLAB Simulink. The developed program uses input operation data of a DC 1500 V metro line. And the simultaneous and multi-rate simulation for DC metro was performed to interface train schedule data with actual railway electrification system and vehicle. In the simulation, the voltage and power measured at each substation are provided during the traction, coasting and breaking mode. From this study, railroad vehicle load can be virtually modeled in the system internally and contribute to verifying new parts of the overall railway electrification systems. Full article

An accurate prediction of the remaining useful life (RUL) of a proton exchange membrane fuel cell (PEMFC) is of great significance for its large-scale commercialization and life extension. This paper aims to develop a PEMFC degradation prediction method that incorporates short-term and long-term predictions. In the short-term prediction, a long short-term memory (LSTM) neural network is combined with a Gaussian process regression (GPR) probabilistic model to form a hybrid LSTM-GPR model with a deep structure. The model not only can accurately forecast the nonlinear details of PEMFC degradation but also provide a reliable confidence interval for the prediction results. The results showed that the proposed LSTM-GPR model outperforms the single models in both prediction accuracy and confidence interval. For the long-term prediction, a novel RUL prediction model based on an extended Kalman filter (EKF) and GPR is proposed. The GPR model is used to solve the problem that the EKF cannot update the model parameters in the prediction stage. The results showed that the proposed EKF-GPR model can achieve better RUL prediction than the model-based approach and the data-driven approach. Full article

Electrochemical energy storage plays a vital role in combating global climate change. Nowadays lithium-ion battery technology remains the most prominent technology for rechargeable batteries. A key performance-limiting factor of lithium-ion batteries is the active material of the positive electrode (cathode). Lithium- and manganese-rich nickel manganese cobalt oxide (LMR-NMC) cathode materials for Li-ion batteries are extensively investigated due to their high specific discharge capacities (>280 mAh/g). However, these materials are prone to severe capacity and voltage fade, which deteriorates the electrochemical performance. Capacity and voltage fade are strongly correlated with the particle morphology and nano- and microstructure of LMR-NMCs. By selecting an adequate synthesis strategy, the particle morphology and structure can be controlled, as such steering the electrochemical properties. In this manuscript we comparatively assessed the morphology and nanostructure of LMR-NMC (Li1.2Ni0.13Mn0.54Co0.13O2) prepared via an environmentally friendly aqueous solution-gel and co-precipitation route, respectively. The solution-gel (SG) synthesized material shows a Ni-enriched spinel-type surface layer at the {200} facets, which, based on our post-mortem high-angle annual dark-field scanning transmission electron microscopy and selected-area electron diffraction analysis, could partly explain the retarded voltage fade compared to the co-precipitation (CP) synthesized material. In addition, deviations in voltage fade and capacity fade (the latter being larger for the SG material) could also be correlated with the different particle morphology obtained for both materials.

Solvent-free (SF) anodes with different carbon materials (graphite, hard carbon, and soft carbon) were fabricated to investigate the stability of different anodes with polytetrafluorethylene (PTFE) degradation. The graphite anode with large volume variation during the charge/discharge process showed poor cycle life performance, while hard carbon and soft carbon with low-volume expansion showed good cycle life. The SF hard carbon electrodes with a high loading of 10.7 mg/cm2 revealed good long-term cycling performance similar to conventional slurry-casting (CSC) electrodes. It demonstrated nearly 90% capacity retention after 120 cycles under a current of 1/3 C with LiNi0.5Co0.2Mn0.3O2 (NCM523) as cathode in coin cell. The rate capability of the high-loading SF electrodes also is comparable to the CSC electrodes. The high stability of SF hard carbon and soft carbon anodes was attributed to its low-volume variation, which could maintain their integrity even though PTFE was defluorinated to amorphous carbon irreversibly. However, the reduced amorphous carbon cannot tolerate huge volume variation of graphite during cycling, resulting in poor stability. Full article

We explore a phase engineering strategy to improve the electrochemical performance of transition metal sulfides (TMSs) in anode materials for lithium-ion batteries (LIBs). A one-pot hydrothermal approach has been employed to synthesize MoS2 nanostructures. MoS2 and MoO3 phases can be readily controlled by straightforward calcination in the (200–300) °C temperature range. An optimized temperature of 250 °C yields a phase-engineered MoO3@MoS2 hybrid, while 200 and 300 °C produce single MoS2 and MoO3 phases. When tested in LIBs anode, the optimized MoO3@MoS2 hybrid outperforms the pristine MoS2 and MoO3 counterparts. With above 99% Coulombic efficiency (CE), the hybrid anode retains its capacity of 564 mAh g−1 after 100 cycles, and maintains a capacity of 278 mAh g−1 at 700 mA g−1 current density. These favorable characteristics are attributed to the formation of MoO3 passivation surface layer on MoS2 and reactive interfaces between the two phases, which facilitate the Li-ion insertion/extraction, successively improving MoO3@MoS2 anode performance.
