Special Issue Information

Dear Colleagues,

Long-duration storage will play a key role in decarbonizing the electricity supply and electrifying the energy economy. Therefore, low-carbon technologies, such as all-solid-state batteries (ASSBs), are being considered one of the solutions to achieve a more sustainable energy future for mobile and stationary applications. Even though significant advances in materials synthesis and properties have been attained over the past decade, novel processing approaches, advanced characterizations, and developments in large-area cells are needed to realize the potential benefits of ASSBs.

To shed light on pathways to enable practical solid-state batteries, this Special Issue calls for advances in basic research and technological development of high energy, high power, and practical ASSBs. We aim to provide a platform for stakeholders, scientists, and engineers to share their research and exchange their ideas. Original research papers, reviews, perspectives, and communications are all welcomed.

Topics of interest in this Special Issue include but are not limited to:

  • Evolution of anode–solid-state electrolyte interfaces (plating vs. stripping);
  • Evolution of cathode–solid-state electrolyte interfaces;
  • Mechanics of cathode materials and interfaces upon charging and discharging;
  • Performance of ASSBs below room temperature;
  • Rational design of solid electrolyte interphases (SEI) / cathode electrolyte interphases (CEI);
  • Manufacturability of ASSBs;
  • Sustainable processing methods of ASSBs.

Garnet-type Ta-doped Li7La3Zr2O12 (LLZO) ceramic solid electrolytes with Ga2O3 additive were synthesized using a conventional solid-state reaction process. When the amounts of Ga2O3 additive were below 2 mol %, the sintered sample has a dense structure composed of grains with an average size of 5 to 10 μm, whereas 3 mol % or more Ga2O3 addition causes a significant increase in grain size above several 10 to 100 μm, due to high-temperature sintering with a large amount of liquid Li-Ga-O phase. At room temperature, the highest total (bulk + grain-boundary) ionic conductivity of 1.1 mS cm−1 was obtained in the sample with 5 mol % Ga2O3 addition. However, this sample was shorted by Li dendrite growth into solid electrolyte at a current density below 0.2 mA cm−2 in galvanostatic testing of the symmetric cell with Li metal electrodes. The tolerance for Li dendrite growth is maximized in the sample sintered with 2 mol % Ga2O3 addition, which was shorted at 0.8 mA cm−2 in the symmetric cell. Since the interfacial resistance between Li metal and solid electrolyte was nearly identical among all samples, the difference in tolerance for Li dendrite growth is primarily attributed to the difference in microstructure of sintered samples depending on the amounts of Ga2O3.

All-solid-state batteries (ASSBs) are among the remarkable next-generation energy storage technologies for a broad range of applications, including (implantable) medical devices, portable electronic devices, (hybrid) electric vehicles, and even large-scale grid storage. All-solid-state thin film Li-ion batteries (TFLIBs) with an extended cycle life, broad temperature operation range, and minimal self-discharge rate are superior to bulk-type ASSBs and have attracted considerable attention. Compared with conventional batteries, stacking dense thin films reduces the Li-ion diffusion length, thereby improving the rate capability. It is vital to develop TFLIBs with higher energy density and stability. However, multiple challenges, such as interfacial instability, low volumetric energy density, and high manufacturing cost, still hinder the widespread application of TFLIBs. At present, many approaches, such as materials optimization and novel architecture design, have been explored to enhance the stability and energy density of TFLIBs. An overview of these discoveries and developments in TFLIBs is presented in this review, together with new insights into the intrinsic mechanisms of operation; this is of great value to the batteries research community and facilitates further improvements in batteries in the near future.
