Description
  • Byl připraven mesoporézní anatas stabilizovaný aluminou pro použití v lithiových bateriích. Adsorpční měření prokázala monotónní nárůst plochy povrchu a objemu pórů se vzrůstající koncentrací Al. Elektrody připravené z tenkých vrstev tohoto materiálu byly charakterizovány cyklickou voltametrií inserce Li, která prokázala velké rozdíly mezi chováním stabilizovaného materiálu a materiálu neobsahujícího Al.

  • A mesoporous electrode material whose structure is composed of anatase nanocrystals stabilized by alumina is reported. Powder X-ray diffraction shows the anatase phase only, but micro-Raman spectroscopy shows that the materials have a core-shell morphology with grains of bulk anatase covered by a thin rutile layer on the surface. This structure is unique when compared to analogous materials stabilized by zirconia (PNNL-1). Nitrogen adsorption isotherms demonstrate a monotonous increase in surface area and mesopore volume with increasing Al content. Thin film electrodes from these materials were characterized by lithium insertion electrochemistry. Cyclic voltammograms exhibit significant differences in Li accommodation in Al-free and Al-stabilized materials.
