Summary: This study reports the utilization of TiO2 nanotube layers decorated with TiO2 nanoparticles as anodes in Li-ion microbatteries for the first time. The capacity of the TiO2 NPs decorated TNT layer anodes increases with the amount of NPs decoration due to the enhancement of the capacitive effect. Conversely, excessive NP loading of the TNT layers leads to reduced areal capacity.

Summary: Gel polymer electrolytes (GPEs) are used as alternatives to liquid electrolytes in lithium-metal batteries (LMBs). Adding diluent 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) to regulate the electrolyte structure improves the electrochemical stability and ion transport properties of GPEs. The addition of TTE enhances ion association and forms a robust and low-impedance solid electrolyte interface (SEI) on the anode surface. This study provides an effective approach for controlling solvation structures in GPEs, which can advance the design of GPE-based LMBs in the future.

Summary: Single-ion conducting polymer electrolytes (SIPEs) eliminate the severe concentration polarization effect by anchoring charge delocalized anions on the side chains of a crosslinked polymer matrix, while plasticized SIPEs usually face a trade-off between conductivity and mechanical strength. A mechanically reinforced SIPE was developed by crosslinking monomer and crosslinker with plasticizer on electrospun nanofibers. This SIPE showed remarkable ionic conductivity, excellent cycling stability, and has great potential in the development of advanced all-solid-state Li-metal batteries.

Summary: In this research, the combination of nitrogen-doped carbon quantum dots (N-CQD), a hydroxide-ion conducting ionomer based on polysulfone (PSU) and polyaniline (PANI) was studied for high-performance nanostructured electrodes in the oxygen reduction reaction (ORR) in alkaline solution. The results showed that N-CQD improved the reduction currents of the electrodes, and PSU-TMA + PANI + GAH-Oct fibers exhibited the best electrocatalytic activity with the lowest slope and most positive half-wave potential. Long-term cycling tests indicated the evolution of the microstructure of the nanocomposite ORR electrode in the mass transport limited region.

Summary: The demand for higher energy density and safety has led to the replacement of conventional Li+ batteries with all-solid-state lithium-ion batteries (ASSLIB). Sulfide solid-state electrolytes (SSEs) with high Li+ conductivity have demonstrated potential for commercialization of ASSLIBs. However, issues such as SSE decomposition at electrodes/electrolyte interfaces and Li-dendrite growth at anodes hinder the commercialization of ASSLIBs.

Summary: The protection of zinc anodes in zinc-air batteries using PVBTMA thin films was found to reduce corrosion, zinc dendrite formation, and improve cyclability and battery efficiency. The PVBTMA layer exhibited selective anion transport, high interface quality, and high ionomer stiffness. The coated batteries showed stable open-circuit voltage and discharge capacity, although degradation was observed in the miniaturized batteries due to air cathode clogging and electrolyte drying or carbonation.
