Special Issue Information

Dear Colleagues,

This Special Issue on All-Solid-State Batteries is focused on new electrolytes, interfaces and manufacturing technologies. Solid-state batteries have high safety and high-energy density, making them suitable for next-generation energy storage devices. However, their energy density reaches a limitation due to the narrow electrochemical window of solid electrolytes. Few electrode materials are compatible with solid electrolytes, preventing their wide application. At the electrolyte/electrode interface, there are side reactions at the anode and cathode. New strategies are needed to reduce the side reactions, thereby improving the electrochemical performance of solid-state batteries. To understand the change in interface, advanced characterizations are necessary, which can offer scientific evidence to increase the interface stability in the future.

In this Special Issue, we are looking for contributions helping to:

  • Understand lithium dendrite formation mechanisms in a battery;
  • Understanding the capacity decay phenomenon in a solid-state battery;
  • Characterization of interface with an in-depth understanding;
  • Develop new in situ approaches to solidify electrolytes;
  • Develop new self-healing materials with ionic conductivity;
  • Determine the impact of the interface on the cycling of the SSB.

This study presents the electrical modeling and characteristic analyses of energy storage systems (ESSs) based on the internal impedance characteristics of batteries to improve ESS stability. Frequencies ranging from 1 kHz to 0.1 Hz were injected into lithium-ion batteries, and the variation of the internal impedance of the batteries was obtained based on the reflected wave to determine the ESS state of charge (SoC) and temperature. The changes in the basic electrochemical impedance spectroscopy characteristics of the ESSs were observed. Specifically, the voltage, temperature, and SoC of an ESS that could be employed as a renewable ESS were analyzed. The impedance characteristics of the ESS were investigated via experimentation and simulation. The ESS comprised an electrically equivalent circuit of a series inductor (LS), series resistor (RS), parallel resistor (RP), and parallel capacitor (CP), as well as a MATLAB program based on its transfer function to generate energy. Furthermore, a method was developed for analyzing the frequency response of ESSs. The feasibility of the proposed electrical modeling was examined for a 58.4 V, 75 Ah, 4.4 kWh ESS. Full article

The lithium-sulfur battery has garnered significant attention from both researchers and industry due to its exceptional energy density and capacity. However, the conventional liquid electrolyte poses safety concerns due to its low boiling point, hence, research on liquid electrolytes has gradually shifted towards solid electrolytes. The polymer electrolyte exhibits significant potential for packaging flexible batteries with high energy density owing to its exceptional flexibility and processability, but it also has inherent disadvantages such as poor ionic conductivity, high crystallinity, and lack of active groups. This article critically examines recent literature to explore two types of polymer electrolytes, namely gel polymer electrolyte and solid polymer electrolyte. It analyzes the impact of polymers on the formation of lithium dendrites, addresses the challenges posed by multiple interfaces, and investigates the underlying causes of capacity decay in polymer solid-state batteries. Clarifying the current progress and summarizing the specific challenges encountered by polymer-based electrolytes will significantly contribute to the development of polymer-based lithium-sulfur battery. Finally, the challenges and prospects of certain polymer solid electrolytes in lithium-sulfur battery are examined, thereby facilitating the commercialization of solid polymer electrolytes.
