Hydrated lithiumnido-boranes for solid–liquid hybrid batteries

Hydrated and anhydrous LiB 11 H 14 salts are prepared through a facile approach. Liquid-like Li + conductivity (10 −2 S cm −1 ) is observed for a-LiB 11 H 14 ·(H 2 O) n at 60 °C. LiB 11 H 14 ·2H 2 O is classified as a new class of ionic liquid as it melts near 70 °C.
