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-doped 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.
