Ion‐Selective Microporous Membranes via One‐Step Copolymerization Enable High‐Performance Redox Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step copolymerization strategy is developed to produce low‐cost microporous ion exchange membranes that boost both the efficiency and lifespan of flow batteries. When combined with organic electrolytes in aqueous systems, these membranes enable safe and cheap flow battery energy storage, supporting the widespread integration of renewable

Design of Terpene‐Based Eco‐Friendly Solution Process for High‐Performance Organic Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
High‐performance, terpene‐processed organic solar cells (OSCs) by designing a new green co‐solvent system consisting of eucalyptol (Eu) and 2‐methyltetrahydrofuran (MeTHF) are developed. The OSCs processed from the optimal ratio of Eu and MeTHF achieve the highest power conversion efficiency (PCE) value of 17.3% reported to date for terpene‐processed ...
