Special Issue Information

Dear Colleagues,

Environmentally friendly power generation technologies play an essential role in future energy supply due to the increased need for less dependence on fossil fuels for primary energy harvesting. The intermittent nature of many renewable energy sources, such as solar or wind power, makes the development and deployment of energy storage systems paramount. In this respect, Lithium-ion batteries dominate the market since their launch by Sony in 1991. However, the rareness and cost of Lithium quests for sustainable and abundant alternatives, like Sodium, Potassium, Magnesium etc. These new “post-lithium” technologies require the discovery and study of new electrode materials, electrolytes and cell components as well as a fundamental understanding of the phenomena occurring during the cell operation.

We invite authors to contribute with original research articles (short communications and full papers) or comprehensive review articles covering the most recent progress and new developments in the design, synthesis, study of materials for lithium and post-lithium systems, such as Sodium, Potassium, Magnesium, Zinc, Calcium, Aluminium etc. as well as those used for high power devices (e.g. in M-ion capacitors).

Potential topics include, but are not limited to, the following:

  • Synthesis of novel positive/negative electrode materials for lithium and post-lithium systems
  • Development of novel electrolytes
  • Metal anodes
  • Design/modeling
  • Hybrid Metal-ion capacitors
  • In operando studies
  • Electrodes engineering/design
  • New electrochemical techniques for battery cells analysis
  • Processes for electrode preparation

Binder-Free Electrode Based on ZnO Nanorods Directly Grown on Aluminum Substrate for High Performance Supercapacitors

Herein, for the first time, the growth of ZnO nanorods directly on aluminum (Al) substrate via a low temperature (80 °C) wet chemical method, and used as binder-free electrode for supercapacitors were reported. XRD pattern and HRTEM images showed that high crystalline nanorods grown on Al substrate with c-axis orientation. Morphological studies revealed that the nanorods possessed well defined hexagon phase with length and diameter of ~2 µm and 100–180 nm, respectively. Raman spectrum of ZnO nanorods showed that the characteristic E2H mode corresponds to the vibration associated with the oxygen atoms of ZnO. The optical properties of ZnO nanorods studied using Room-temperature PL spectra revealed a near-band-edge (NBE) peak at ~388 nm emission and deep level (DLE) at ~507 nm. Electrochemical measurements showed that ZnO nanorods on Al substrate exhibited remarkably enhanced performance as electrode for supercapacitors with a value of specific capacitance of 394 F g−1 measured with scan rate of 20 mV s−1. This unique nanorods structures also exhibited excellent stability of >98% capacitance retention for 1000 cycles that were measured at 1A g−1. The presented easy and cost-effective method might open up the possibility for the mass production of binder-free electrodes for efficient electrochemical energy storage devices. Full article

Recent critical issues regarding next-generation energy storage systems concern the cost-effective production of lightweight, safe and flexible supercapacitors yielding high performances, such as high energy and power densities as well as a long cycle life. Thus, current research efforts are concentrated on the development of high-performance advance electrode materials with high capacitance and excellent stability and solid electrolytes that confer flexibility and safety features. In this work, emphasis is placed on the binder-free, needle-like nanostructured Mn/MnOx layers grown onto graphite-foil deposited by reactive sputtering technique and to the polymer gel embedded ionic electrolytes, which are to be employed as new flexible pseudocapacitive supercapacitor components. Microstructural, morphological and compositional analysis of the layers has been investigated by X-ray diffractometer (XRD), Field Emission Scanning Electron Microscope (FE–SEM) and X-ray photoelectron spectroscopy (XPS). A flexible lightweight symmetric pouch-cell solid-state supercapacitor device is fabricated by sandwiching a PPC-embedded ionic liquid ethyl-methylimidazolium bis (trifluoromethylsulfonyl) imide (EMIM)(TFSI) polymer gel electrolyte (PGE) between two Mn/MnOx@Graphite-foil electrodes and tested to exhibit promising supercapacitive behaviour with a wide stable electrochemical potential window (up to 2.2 V) and long-cycle stability. This pouch-cell supercapacitor device offers a maximum areal capacitance of 11.71 mF/cm2@ 0.03 mA/cm2 with maximum areal energy density (Ea) of 7.87 mWh/cm2 and areal power density (Pa) of 1099.64 mW/cm2, as well as low resistance, flexibility and good cycling stability. This supercapacitor device is also environmentally safe and could be operated under a relatively wide potential window without significant degradation of capacitance performance compared to other reported values. Overall, these rationally designed flexible symmetric all-solid-state supercapacitors signify a new promising and emerging candidate for component integrated storage of renewable energy harvested current.
