Special Issue Information

Dear Colleagues,

As next-generation energy storage devices, solid state batteries offer great promise with higher energy density, reduced cost, wider operating temperature range and improved safety for the applications of electronic devices, electrical vehicles and smart grids. As the most critical component, electrolytes for solid state batteries including solid polymer electrolytes, inorganic solid electrolytes (such as oxides, sulfides, halides and so on) and their combinations are in development. Nevertheless, there are still significant challenges relevant to these solid electrolytes that discourage their practical applications, such as the limited types and low ionic conductivity of solid-state electrolytes, high charge-transfer impedance, interfacial issues and dendrite growth.

We are therefore organizing a Special Issue on “Electrolytes for Solid State Batteries” in Batteries (ISSN: 2313-0105). This Special Issue will present papers addressing the original and innovative papers as well as reviews and opinion pieces relevant to electrolyte and electrolyte surface for all kinds of solid-state batteries.

Potential topics include (but are not limited to):

  • Quasi/all-solid polymer electrolytes;
  • Inorganic solid electrolytes (such as oxides, sulfides, halides, etc.);
  • Hybrid solid electrolytes;
  • Eutectogel electrolytes;
  • In situ fabricated solid-state electrolytes;
  • Interfacial design and evolution;
  • Ion-conductive mechanisms;
  • Solid-state batteries (such as lithium, sodium, etc. );
  • Safety evaluation;
  • Characterization techniques and theoretical computations/simulations of electrolytes and batteries;
  • Materials Genome Initiative, artificial intelligence (AI) and machine learning (ML) of solid electrolytes and batteries.

In view of your international standing as a research scientist, we cordially invite you and your colleagues to contribute a manuscript. The deadline is set as 18 January 2023.

Li6PS5Cl possesses high ionic conductivity and excellent interfacial stability to electrodes and is known as a promising solid-state electrolyte material for all-solid-state batteries (ASSBs). However, the optimal annealing process of Li6PS5Cl has not been studied systematically. Here, a Box–Behnken design is used to investigate the interactions of the heating rate, annealing temperature, and duration of annealing process for Li6PS5Cl to optimize the ionic conductivity. The response surface methodology with regression analysis is employed for simulating the data obtained, and the optimized parameters are verified in practice. As a consequence, Li6PS5Cl delivers a rather high conductivity of 4.45 mS/cm at 25 °C, and ASSB consisting of a LiNi0.6Co0.2Mn0.2O2 cathode and lithium anode shows a high initial discharge capacity of 151.7 mAh/g as well as excellent cycling performances for more than 350 cycles, highlighting the importance of the design of experiments.

With the merits of having excellent safety, being low cost and being environmentally friendly, zinc-ion hybrid supercapacitors (ZHSCs) are expected to be widely used in large-scale energy storage and flexible wearable devices. However, limited by their sluggish kinetic process, ZHSCs suffer from low-specific capacity and poor cycling stability at high cathode mass loading. Herein, a novel designed oxygen-rich hierarchical porous carbon (HPOC) is obtained by a one-step strategy of synchronous activation and templated for high-performance ZHSCs. The fabricated ZHSCs with HPOCs show significant improvement in Zn-ion storage capability, with a capacity of 209.4 mAh g−1 at 0.1 A g−1 and 108.3 mAh g−1 at 10 A g−1. Additionally, the cycling stability is excellent, with 92.3% retention after 4000 cycles. Furthermore, an impressive areal capacity of 1.7 mAh cm−2 is achieved, even with a high mass loading of 12.5 mg cm−2. More importantly, the flexible quasi-solid state ZHSCs also show a considerable capability (183.5 mAh g−1 at 0.1 A g−1) and a high energy density of 178.0 Wh kg−1. This promising result suggests a valuable route to produce functional nanocarbon materials for zinc storage applications. Full article

All-solid-state lithium batteries are a promising alternative to commercially available lithium-ion batteries due to their ability to achieve high energy density, safety, and compactness. Electrolytes are key components of all-solid-state batteries, as they are crucial in determining the batteries’ efficiency. Herein, the structure of LiM2(PO4)3 (M = Ti, Ge, Zr) and lithium-ion migration mechanisms are introduced as well as different synthetic routes and doping (co-doping), and their influence on conductivity is discussed. The effective methods of reducing electrolyte/electrode interface resistance and improving ion-conducting properties are summarized. In addition, different polymer/NASICON composites are considered. The challenges and prospects of practical applications of NASICON-type lithium phosphates as electrolytes for all-solid-state batteries are discussed. Full article

In this paper, the methods used to enhance the conductivity of LiBH4, a potential electrolyte for the construction of solid-state batteries, are summarized. Since this electrolyte becomes conductive at temperatures above 380 K due to a phase change, numerous studies have been conducted to lower the temperature at which the hydride becomes conductive. An increase in conductivity at lower temperatures has generally been obtained by adding a second component that can increase the mobility of the lithium ion. In some cases, conductivities at room temperature, such as those exhibited by the liquid electrolytes used in current lithium-ion batteries, have been achieved. With these modified electrolytes, both lithium metal and lithium-ion cells have also been constructed, the performances of which are reported in the paper. In some cases, cells characterized by a high capacity and rate capability have been developed. Although it is still necessary to confirm the stability of the devices, especially in terms of cyclability, LiBH4-based doped electrolytes could be employed to produce solid-state lithium or lithium-ion batteries susceptible to industrial development.

Metal–sulfur batteries, especially lithium/sodium–sulfur (Li/Na-S) batteries, have attracted widespread attention for large-scale energy application due to their superior theoretical energy density, low cost of sulfur compared to conventional lithium-ion battery (LIBs) cathodes and environmental sustainability. Despite these advantages, metal–sulfur batteries face many fundamental challenges which have put them on the back foot. The use of ether-based liquid electrolyte has brought metal–sulfur batteries to a critical stage by causing intermediate polysulfide dissolution which results in poor cycling life and safety concerns. Replacement of the ether-based liquid electrolyte by a solid electrolyte (SEs) has overcome these challenges to a large extent. This review describes the recent development and progress of solid electrolytes for all-solid-state Li/Na-S batteries. This article begins with a basic introduction to metal–sulfur batteries and explains their challenges. We will discuss the drawbacks of the using liquid organic electrolytes and the advantages of replacing liquid electrolytes with solid electrolytes. This article will also explain the fundamental requirements of solid electrolytes in meeting the practical applications of all solid-state metal–sulfur batteries, as well as the electrode–electrolyte interfaces of all solid-state Li/Na-S batteries.
