Lithium metal battery (LMB) possessing a high theoretical capacity is promising candidate of advanced energy storage devices. However, its safety and stability are challenged by lithium dendrites the leakage liquid electrolyte. Here, self-enhancing gel polymer electrolyte (GPE) created in situ polymerizing 1,3-dioxolane (DOL) nanofibrous skeleton for enabling safe LMB.

Perovskite solar cells in which 2D perovskites are incorporated within a 3D perovskite network exhibit improved stability with respect to purely systems, but lower record power conversion efficiencies (PCEs). Here, breakthrough is reported achieving enhanced PCEs, increased stability, and suppressed photocurrent hysteresis by incorporating n-type, low-optical-gap conjugated organic molecules into 2D:3D mixed composites. The resulting ternary perovskite-organic composites display extended...
