Lithium lanthanum titanate as an electrolyte for novel lithium ion battery systems

Solid electrolytes with high lithium conductivity may serve as useful components for enabling novel lithium ion battery system design. This work demonstrates the integration of lithium lanthanum titanate (Li0.29La0.57TiO3) into a battery system separating electrodes based on liquid electrolyte. Specifically, binder free electrodes based on graphite and LiCoO2were tested against lithium metal in liquid electrolyte with an intermediate solid electrolyte. The system was characterized by cyclic voltammetry, and electrochemical impedance.
