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: Bi2S3 nanorods encapsulated into carbon nanotubes (CNTs) were prepared as an anode for lithium-ion batteries (LIBs), with the CNTs acting as a physical barrier to segregate Bi2S3 nanorods and accommodate volume variation. The electrode showed high capacity and stability in LIBs. Additionally, as a sulfur host, the electrode exhibited advanced performance in lithium-sulfur batteries (LSBs) due to enhanced conductivity and curbed lithium polysulfide diffusion.

Summary: This study reveals that the conventional PVDF binder used in Li-ion batteries is electrochemically unstable at relatively low potentials, degrading and forming a LiF layer during charge and discharge cycles. The degradation continues over subsequent cycles, especially under increased cycling temperatures. This has implications for interpreting electrochemical data and understanding the stability of PVDF-based electrodes, particularly in high-voltage battery cells with extreme cycling conditions.

Summary: This study evaluates the economic benefits of deploying rechargeable batteries for demand peak shaving and price arbitrage. A novel modeling approach is proposed for selecting battery technology and size, optimizing charge and discharge scheduling. Simulation results from a Swiss electricity service provider show that economically viable battery deployment requires careful selection of energy capacity and power units. Additionally, findings suggest that the cycle lifetime of a battery has minimal impact on achievable revenues, making second-use batteries a potentially attractive option for stationary energy storage.

Summary: A suite of analytical techniques were applied to investigate the limitations of fast cycling in composite graphite electrodes in all-solid-state cells with sulfide electrolytes, identifying cracks in the electrodes, poor percolation of conducting particles, and the formation of compounds increasing the interfacial resistance. Despite kinetic limitations, excellent long-term cycling performance was demonstrated at specific rates, suggesting slow self-passivation processes at the interface.
