Special Issue Information

Dear Colleagues,

Batteries and supercapacitors are essential electrochemical energy storage systems (ESSs) in a wide range of fields, such as portable electronic devices, electric vehicles, smart grids, and aerospace. Electrolyte is a key part of batteries and supercapacitors, which has a significant impact on the electrochemical properties of the devices. Understanding the relationship of the electrochemical performance of devices and the electrolyte properties is of great significance due to its importance in creating higher-performance batteries and supercapacitors. Using novel electrolytes, batteries are expected to have the capability to support higher voltage, fast charging, and charging/discharging over a wide temperature range and non-flammability; and supercapacitors are expected to further improve energy density by increasing the cell voltage.

In this Special issue, we are looking for contributions helping to introduce recent advances and breakthroughs in electrolyte design for batteries and supercapacitors, addressing the correlation between battery performance, solvation structure, and solid-electrolyte-interphase chemistry, as well as novel electrolytes for batteries and supercapacitors to enable the enlargement of the electrochemical window, increase the ion conductivities and safety, improve the environmental friendliness, and reduce the cost.

Topics of interest include but are not limited to:

  • Organic liquid electrolytes;
  • Inorganic solid electrolytes;
  • Ionic liquid electrolytes;
  • Polymer-based electrolytes;
  • Aqueous electrolytes;
  • Hybrid electrolytes;
  • Water-in-salt electrolytes;
  • Eutectic solvent-based electrolytes;
  • High-concentration ether-based electrolytes;
  • Electrolyte additives.

The combination of Li-metal anode and high-voltage cathode is regarded as a solution for the next-generation high-energy-density secondary batteries. However, a traditional electrolyte is either incompatible with the Li-metal anode or vulnerable to high voltage. This work reports a 1 M dual-salts Localized-High-Concentration-Electrolyte with Fluoroethylene carbonate (FEC) additive. It enables stable cycling of Li||LiNi0.8Co0.1Mn0.1O2 (NMC811) battery, which shows 81.5% capacity retention after 300 cycles with a charge/discharge current density of 1 C and a voltage range of 2.7–4.4 V. Scanning electron microscopy (SEM) images show that this electrolyte not only largely reduced Li dendrites and ‘dead’ Li on anode surface but also well protected the microstructure of NMC811 cathode. Possible components of both solid-electrolyte interlayer (SEI) and cathode-electrolyte interlayer (CEI) were characterized by energy-dispersive X-ray spectroscopy (EDX). The result illustrates that FEC protected Li salts from decomposition on the anode side and suppressed the decomposition of solvents on the cathode side. Full article
