Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to this Special Issue on “Recent Progress in Advanced Materials for Solid-State Lithium Batteries”. This Special Issue aims to give an overview of recent developments on electrode and electrolyte materials and composites for application in solid-state lithium-ion batteries (SSLIB). In recent years, SSLIB have emerged as one of the most promising technologies for replacing conventional lithium-ion batteries since they can offer simpler battery design with improved safety and durability. However, the mechanical and (electro)chemical instability of solid electrolytes, high interfacial resistance and insufficient interfacial contact between electrode and electrolyte remain challenging issues that limits their practical application. Alongside technological developments, the need for sustainable battery development is considered essential to achieve carbon neutrality. Therefore, this Special Issue aims to provide fundamental understanding to overcome these challenges and make substantial contributions to the development of safer, clean and sustainable SSLiB.

Potential topics include but are not limited to:

  • Solid electrolytes design and formulation;
  • Synthesis, characterization and properties of the electrode materials;
  • Electrochemical performance and stability;
  • Interfacial phenomena and charge transfer resistances;
  • Thin film batteries.

Authors are welcome to submit their latest research in the form of original full articles, communications, or reviews on this topic.

At present, LiNi1/3Co1/3Mn1/3O2 (NCM) is a widely used material in the commercial market due to the easy control of the preparation process and usage environment. However, its capacity keeps fading when the cut-off voltage increases. In this research, an Li1.3Al0.3Ti1.7(PO4)3 (LATP) coating method is proposed to improve the cycle performance of LiNi1/3Co1/3Mn1/3O2 at a high cut-off voltage of 4.6 V. The battery prepared with LATP-modified NCM exhibits an increased discharge capacity retention of 92.37% after 100 cycles at 0.2C (1C = 200 mA g−1), while the bare NCM only presents 64.28%. Our results indicate that LATP-surface coating might be a useful method to increase the cycle stability of NCM and other high-capacity cathode materials. Full article

Cation-disordered rock-salt cathode material is a promising material for next-generation lithium-ion batteries due to their extra-high capacities. However, the drawbacks of large first-cycle irreversible capacity loss, severe capacity decay, and lower discharge voltage have undoubtedly hindered their application in commercial systems. In this study, cation doping (Mo4+) and atomic layer deposition (ALD) techniques were used to synthetically modify the Li1.2Ti0.4Mn0.4O2 (LTMO) material to improve the cycling stability. First, the optimal Mo-doped sample (Mo01) with the best electrochemical performance among the different doping amounts was selected for further study. Second, the selected sample was subsequently coated with an Al2O3 layer by the ALD technique to further optimize its electrochemical performance. Results show that the LTMMO/24Al2O3 sample, under optimal conditions, could obtain a specific discharge capacity of up to 228.4 mAh g−1 after 30 cycles, which is much higher than that of the unmodified LTMO cathode material. Our work has provided a new possible solution to address some of the capacity fading issues related to the cation-disordered rock-salt cathode materials. Full article

The safety problem caused by lithium dendrite of lithium metal anode and the rapid capacity decay problem caused by the shuttle effect of polysulfide and polyselenide during the charge and discharge of selenium disulfide cathode limit the application of lithium selenium disulfide batteries significantly. Here, a fibrous ATFG-COF, containing rich carbonyl and amino functional groups, was applied as the separator coating layer. Density Functional Theory (DFT) theoretical calculations and experimental results showed that the abundant carbonyl group in ATFG-COF had a positive effect on lithium ions, and the amino group formed hydrogen bonds with bis ((trifluoromethyl) sulfonyl) azanide anionics (TFSI), which fixed TFSI in the channel, so as to improve the transfer number of lithium ions and narrow the channels. Therefore, ATFG-COF fiber coating can not only form a rapid and uniform lithium-ion flow on the lithium anode to inhibit the growth of lithium dendrites, but also effectively screen polysulfide and polyselenide ions to suppress the shuttle effect. The Li-SeS2 cell with ATFG-COF/polypropylene (ATFG-COF/PP) separator exhibited good cycle stability at 0.5 C and maintained a specific capacity of 509 mAh/g after 200 cycles. Our work provides insights into the design of dual-function separators with high-performance batteries. Full article
