From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Cold‐Sublimating Quasi‐Solid Additive Enables High Efficiency and Long Operational Stability Binary Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Cold‐sublimating quasi‐solid mDF acts as an in situ‐removable transient structuring agent that broadens solvent‐removal, accelerates intermediate crystallization, and tightens π–π stacking in PM6:L8‐BO OSCs. Offering residue‐free morphology control, mDF‐treated OSCs enable high efficiency and a markedly extended operational lifetime (T80 = 477 h ...
