Investigations on morphological and electrochemical changes of all-solid-state thin film battery cells under dynamic mechanical stress conditions
mechanical flexibility is one of the main advantages of the solid-state battery technology. Mechanically flexible thin film, all solid-state Li-ion batteries are supposed to be the main power sources in emerging [...] emerging technologies such as flexible electronics, wearables, etc. However, if a flexible solid-state device is exposed to repeated external mechanical load, introducing additional aging mechanisms might [...] cell during dynamic bending were investigated in detail. Therefore, mechanically flexible, all solid-state MoO3/LiPON/Li battery cells were fabricated on a polymer substrate. Battery cells were exposed to
