HIGH ENERGY DENSITY: CHANCES AND CHALLENGES OF OXIDE-BASED SOLID-STATE BATTERIES
In order to put oxide-based solid-state batteries into practice (Figure 1), systematic investigations were carried out to answer questions of chemical stability between solid-state electrolyte and electrode materials [Miara, 2016]. In addition to these results, it will be described how H2O and CO2 c...

520 | |a In order to put oxide-based solid-state batteries into practice (Figure 1), systematic investigations were carried out to answer questions of chemical stability between solid-state electrolyte and electrode materials [Miara, 2016]. In addition to these results, it will be described how H2O and CO2 can affect solid electrolytes. Findings of various analysis techniques, especially depth-resolved methods like nuclear reaction analysis, Rutherford backscattering spectrometry, and secondary ion mass spectrometry, and raising issues will be presented and discussed in this talk. Figure 1: Oxide-based bulk solid-state battery based on LiCoO2 / Li7La3Zr2O12 mixed cathode, Li7La3Zr2O12 electrolyte, and Li metal anode.Up to now, research has shown that Li7La3Zr2O12 garnets (LLZ) and Lithium phosphorus oxynitrides (LiPON) are apparently the only electrolyte materials that can resist the low reduction potential of metallic Lithium as well as high electrochemical potentials up to about 5 V vs. Li/Li+. Lithium ion conductors based on LLZ are particularly promising solid electrolytes for solid-state Lithium batteries due to their high Lithium ion conductivity. However, the implementation into a practical battery cell is impeded by challenges arising from material processing which are partially associated with high temperature heat treatments [Uhlenbruck, 2016; Tsai, 2019]. Moreover, the use of metallic Lithium as anode is not as straightforward as expected: Lithium metal filament growth can also occur within ceramic electrolytes [Tsai, 2016].AcknowledgementsThe authors gratefully acknowledge financial support of the Helmholtz Association of German Research Centers under the grant “Speicher und Vernetzte Infrastrukturen“ and Helmholtz Institute Münster (HI MS), and of the German Federal Ministry of Education and Research under grant numbers 13N9973, 03SF0477A and 03X4634C; the authors are responsible for the content of this publication.ReferencesL.
