Challenges and opportunities in the wet processing of sulfide-based solid electrolytes for the cathode fabrication for solid-state lithium-ion batteries
Small-sized electrolyte particles are beneficial for the performance of solid-state batteries (SSBs), as they enhance the interconnection between the corresponding materials and thereby improve lithium-ion mobility, leading to reduced internal lithium-ion resistance. In this study, the comminution of commercial Li₆PS₅Cl argyrodite electrolyte was investigated under wet conditions in xylene using the dual centrifuge Delta Vita […]
Smart Organic Molecules for Sulfide Batteries: Trapping H₂S and Stabilizing High-Voltage Interfaces
Solid state batteries are widely regarded as a key technology for next generation energy storage, with sulfide based electrolytes offering high ionic conductivity and compatibility with lithium metal. However, their development is severely constrained by interfacial instabilities originating from the solid–solid nature of the system and the intrinsic chemical reactivity of sulfides. Loss of interfacial […]

Lithium plating in commercial lithium-ion cells: An extensive study combining electrical methods with post-mortem analysis
Lithium plating is a safety-critical phenomenon that occurs mainly during fast charging of lithium-ion batteries at cold temperatures. It is caused on the anode by the limited capability to absorb lithium ions at the desired rate. Reversible and irreversible Li plating can be accompanied by the formation of dendrites and lead to safety-critical short circuits. […]
Short-Term Trading for Grid-Scale Battery Energy Storage Systems
We extend a recent grid-scale battery high-frequency-intraday-trading dynamic programming formulation of the rolling intrinsic by integrating price forecast information.
