Summary: The study demonstrates the production of rechargeable Na/Cl-2 and Li/Cl-2 batteries with a microporous carbon positive electrode, aluminium chloride in thionyl chloride as the electrolyte, and either sodium or lithium as the negative electrode. The reversible Cl-2/NaCl or Cl-2/LiCl redox in the microporous carbon allows for rechargeability at the positive electrode side, while the thin alkali-fluoride-doped alkali-chloride solid electrolyte interface stabilizes the negative electrode, both of which are critical for secondary alkali-metal/Cl-2 batteries.

Summary: Layered oxide cathode active materials suffer from interfacial structural instability when coupled with sulfide solid-state electrolytes. Here, the authors propose a gradient coating with a lithium oxythiophosphate layer that can stabilize the cathode|solid-state electrolyte interface. This coating effectively hinders structural degradation and allows for a specific discharge capacity of 128mAh/g after almost 250 cycles.

Summary: This paper investigates the effect of Li-H exchange amount on the conductivity of Li2+xOH1-xBr samples. The results show that increasing the Li-H exchange amount can enhance the Li+ conductivity, while simultaneously reducing the crystallite size. The highest conductivity is achieved in the Li-excess Li2.2OH0.8Br composition.

Summary: This study proposes a modified poly(ethylene oxide) (PEO)-based solid polymer electrolyte (SPE) with graphene oxide nanosheets (GO-PSLi) to address the issues of insufficient Li-ion transporting channels and inhomogeneous Li deposition in lithium metal batteries (LMBs). The introduction of GO-PSLi enhances the dispersion of nanoparticles and provides fast Li-ion diffusion pathways. Additionally, PSLi chains reduce the crystallization of composite SPEs and accelerate Li-ion migration. The as-prepared composite SPEs exhibit improved ionic conductivity and lithium transference number, and show excellent lithium plating/stripping performances and cycling abilities in Li||Li and Li||LiFePO4 batteries. This study presents a facile and practical strategy for the development of advanced PEO-based SPEs for safe and dendrite-free solid-state LMBs.

Summary: This study demonstrates that an electronic conductor interlayer, such as aluminum or silver, can greatly enhance the interfacial stability between Li1.3Al0.3Ti1.7(PO4)(3) (LATP) solid-state electrolyte and lithium metal in lithium-ion batteries. By employing various techniques, the researchers unveil the mechanism behind the enhanced interfacial stability and discover that combining the electronic conductor interlayer with a solid polymer electrolyte (SPE) can effectively protect LATP and improve the cycling performance of the battery. This work provides an in-depth understanding of the mechanism and offers a universal interface architecture to enhance the cyclability of solid-state batteries.

Summary: Effective utilization of Li-metal electrodes is crucial for enhancing the specific energy of lithium-oxygen batteries. Through optimizing formulations based on solvent, salt, and ionic liquid, stable Li plating/stripping performances and improved performance in Li-O-2 full cells were achieved. Introducing non-volatile IL had negligible disrupting effects on critical stabilizing interactions between Li+ and DMSO.

Summary: This study develops an interpenetrating polymer network electrolyte (IPNE) comprising networked solid polymer electrolytes (SPEs) and lithium bis(fluorosulfonyl) imide (LiFSI) to address the challenges in all-solid-state batteries. The synergy between the two SPEs results in high ionic conductivity and a high Li-transference number. The exploitation of the synergy between polymer networks is a promising approach to further developing SPEs.
