Summary: This study proposes a method using titanium (IV) isopropoxide as a coupling agent to enhance the thermotolerant and mechanical properties of nanofibers, leading to the preparation of a porous Sb2S3/TiO2/C nanofiber membrane with good flexibility. Without the need for slurry coating processes, the porous Sb2S3/TiO2/C nanofiber membranes can be cut into electrodes and directly assembled into lithium-ion half-cells or full-cells.

Summary: The rapid development of electric vehicles has created a need for high energy density lithium-ion batteries. Increasing the thickness of electrodes is an effective way to enhance the energy density, but the traditional wet process has limitations. In this study, we introduce a dry, solvent-free process using a phenoxy resin binder, which produces homogeneous thick electrodes with improved electrochemical stability.

Summary: The rapid growth of electric vehicles and electronic devices has led to a significant increase in the number of spent batteries that have reached the end of their life. It is crucial to find a sustainable and efficient approach to battery recycling. A type of MXene material, AD-Ti(3)C(2)Tz electrode, has been developed and directly used as free-standing anodes for lithium-ion and sodium-ion batteries without the need for binder or carbon additives. The AD-Ti(3)C(2)Tz electrode exhibits excellent electrochemical performance and can be easily recycled, further converted into TiO2/C hybrids with adjustable carbon content, enabling its second life in various applications.

Summary: Silicon-coated molybdenum sulfide nanosheets (Si-MoS2 TFs) were prepared using metal organic chemical vapor deposition (MOCVD) and radio frequency (RF) sputtering. Si-MoS2 TFs showed excellent reversibility and high capacity in thin-film Li-ion batteries, addressing the issues of polysulfide dissolution and shuttling effect. The synergistic effect of MoS2 and Si enhanced the ability to store Li ions and complemented each other in repeated conversion and alloying reactions.

Summary: This article reviews the technological trends and applications of lithium-phosphorous-oxynitride (LiPON) films in thin-film batteries. LiPON films are actively used in lithium anode thin-film batteries due to their excellent contact stability with lithium and advantages in thin-film formation. Furthermore, LiPON films are explored as protective layers to prevent surface deterioration of electrode materials. Multiple studies have been conducted to improve the performance degradation of rechargeable lithium batteries by utilizing LiPON films. Finally, the technical tasks required for enhancing the utilization of LiPON films in the field of thin-film batteries or electrode surface modification are summarized.

Summary: Silicon thin-film is a promising anode material for lithium-ion batteries due to its high cycle stability and initial coulombic efficiency. However, the low areal capacity and tendency for layer misalignment and separation limit its practicality. By studying silicon films with a thickness of 700 nm, researchers found that the volume of silicon does not recover after delithiation, causing significant swelling. The non-uniform film substrate helps to maintain a relatively stable structure. Despite these challenges, the specific capacity retention of the silicon film electrode after 100 cycles is 64.35%.
