Quasi-solid-state electrolytes promise the safety of ceramics, the flexibility of polymers, and the conductivity of liquids—yet the “how” behind their superior ion transport has remained murky. Now, a joint team from Fudan University and the National Institute for Cryogenic & Isotopic Technologies (Romania), led by Professors Aishui Yu and Tao Huang, delivers a decisive answer in Nano-Micro Letters. Their review, “Enhancement of Li⁺ Transport Through Intermediate Phase in High-Content Inorganic Composite Electrolytes,” decodes the hidden chemistry that lets lithium sprint across solid/liquid boundaries.
