Confining surface oxygen redox in double perovskites for enhanced oxygen evolution reaction activity

Nickel-based double perovskites AA’BB’O6 are an underexplored class of oxygen evolution reaction (OER) catalysts. In particular, BaSrNiWO6 exhibits high oxygen evolution activity, attributed to the evolution of a highly OER active surface phase. The redox transformation of Ni2+(3d8) to Ni3+(3d7) combined with partial W dissolution into the electrolyte drives an in-situ reconstruction of the surface to an amorphized, NiO-like layer, promoting oxygen redox in the OER mechanism.

Decentralized hydrogen-based stationary energy storage systems complemented by smart control can provide increased operational flexibility in the energy system

While the electrification of the energy system implies a reduction of greenhouse gas emissions greatly beneficial to society, it can also pose technical challenges. The most notable among these are that the capacity of the local electric grid may be exceeded, along with the occurrence of imbalances between decentralized renewable energy production and final consumption. Hydrogen-based energy storage systems (HESS) are regarded as promising solutions to address these challenges. However, the feasibility has not been demonstrated and the involved processes are not well characterized on a technical relevant power level, so far.

Understanding the Interplay between Artificial SEI and Electrolyte Additives in Enhancing Silicon Electrode Performance for Li-Ion Batteries

Maintaining a stable solid electrolyte interphase (SEI) is crucial for Li-ion battery safety, especially with high-capacity anode containing silicon. Therefore, our study explored long-term cycling of Si electrodes with artificial alucone-based SEI, deposited by molecular layer deposition (MLD) in combination with a fluoroethylene carbonate (FEC) electrolyte additive. MLD of flexible Li-ion permeable artificial SEI coatings onto electrode resulted in improved capacity, enhanced Si electrode cycle life and capacity retention.
