Efficient Non‐Invasive Rejuvenation of Spent Lithium Iron Phosphate Batteries Through Controlled Overdischarge

Advanced Materials, EarlyView.
This strategy rejuvenates spent lithium iron phosphate battery by non‐invasively targeting Li+ trapped within the solid‐electrolyte interphase (SEI). This method mitigates copper dissolution and reduces Li/Fe antisite defects, achieving 9.56% capacity recovery and 214 cycles lifespan extension. The process requires only 3 MJ kg−1 of energy and emitting

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

Advanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Gels as battery separators for soluble electrode cells [PDF]

, 1977
Gels are formed from silica powders and hydrochloric acid. The gels are then impregnated into a polymeric foam and the resultant sheet material is then used in applications where the transport of chloride ions is desired.

Optimal Flow Factor Determination in Vanadium Redox Flow Battery Control

IEEE Access
The optimization of vanadium redox flow batteries (VRFBs) is closely related to the flow rate control: a proper regulation of the electrolyte flow rate reduces losses and prolongs battery lifetime. To this end, a flow factor control strategy in VRFBs was
