Abstract
Materials required for the fabrication of a micro lithium-ion battery have been synthesized. Coin cells made of the above materials showed very promising features for future development of microbatteries. Solid electrolytes with high lithium conductivity may serve as useful components for enabling novel lithium ion battery system design. This work attempts to demonstrate the possible integration of lithium lanthanum titanate (Li0.390La0.537TiO3) materials into an all-solid battery system with Li[Li1/3Ti5/3]O4 as anode material in combination with a high voltage spinel of the family Li2(M1M2)xMn3-xO8 cathode, namely the Li2Co0.4Fe0.4Mn3.2O8 material. The cell operates along the expected voltage levels, demonstrating the feasibility of this concept in the advanced lithium-ion battery technology.
