Energy Storage
The transition from fossil fuels to renewable energies goes along with increasing requirements for batteries in the field of electro mobility and energy storage. One possible improvement for safety and energy density of Lithium ion batteries is the replacement of the organic electrolyte with a solid Li ion conductor. A promising candidate for such a future solid electrolyte in a so called all solid state battery is the oxide ceramic Li7La3Zr2O12 (LLZ). It exhibits an excellent performance regarding the stability against metallic Lithium and compatibility with high voltage electrode materials due to its wide electrochemical window. To improve the overall conductivity of the cell, the material is deposited using thin film processes. Because of the correlation between the ionic conductivity and the Lithium content in the LLZ, a method to quantify the Lithium content in thin films by secondary ion mass spectrometry is presented.
