Understanding the Hydration Process of Salts: The Impact of a Nucleation Barrier

The solid-state hydration of salts has gained particular interest within the frame of thermochemical energy storage. In this work, the water vapor pressure-temperature (p-T) phase diagram of the following thermochemical salts was constructed by combining equilibrium and nonequilibrium hydration experiments: CuCl 2 , K 2 CO 3 , MgCl 2 ·4H 2 O,...

Chlorine Doping of Amorphous TiO2 for Increased Capacity and Faster Li+-Ion Storage

Titania (TiO2) offers a high theoretical capacity of 336 mAh g-1 with the insertion of one Li per Ti unit. Unfortunately, the poor ionic and electronic conductivity of bulk TiO2 electrodes limits its practical implementation. Nanosizing titania below ∼20 nm has shown to increase the rate performance and accessible capacity but still not more...
