Abstract Garnet-type Ta-doped Li7La3Zr2O12 (LLZTO) solid electrolyte has been widely investigated for secondary Li ionic or metal batteries at ambient temperature. Because of the increasing ionic conductivity of LLZTO with temperature, we applied the LLZTO solid electrolyte to thermal battery working at 550℃. The LLZTO presents ultrahigh specific energy as the discharge specific energy and specific power is 605 W h/kg and 2.74 kW/kg at 100 mA/cm2 with a cut-off voltage of 1.8 V, respectively. This is larger than the LiF–LiCl-LiBr electrolyte which is commonly used in thermal battery with a specific energy of 514 W h/kg. The internal resistance of the single cell reaches 0.65 Ω, but the specific energy remains at about 400 W h/kg as the current density increases to 400 mA/cm2. We report the application of LLZTO in thermal battery with high specific energy, large current, and high voltage discharge for the first time, broadening the application range of solid electrolytes.

Abstract Reliability of Li-ion batteries (LIB) is major concern for FHE devices due to needs of flexibility without degradation of state of health (SOH) of the LIB. In this regard, a thin form factor based LIB below 1mm of thickness is regarded as the candidate material to meet such needs because it is able to be fold, bent and twisted with limited performance drop. In addition to this, LIB has high specific power (W/Kg) and high specific energy (Wh/Kg) and a lower memory effect which could make the LIB more attractive for wearable applications. While studies on chemo-physical effect such as SEI growth, material decay, etc. due to repeated charging and discharging LIB has been conducted greatly, but such effects due to the flexing LIB have been rarely conducted. In this study, degradation of thin-flexible power source reliability has been studied under twist, flexing, flex-to-install of magnitude to replicate stresses of daily motion of human body using motion-control setups in a lab-environment. Additionally, AI-based regression model has been developed to predict the SOH of the battery with multiple variables including physical, ambient and chemo-mechanical experimental conditions which could be challenged to be treated by the manpower. The developed models can be used to predict the life of the battery and analyze acceleration factors between test conditions and use conditions for variety of test conditions based on the individual variables and their interactions.
