All-Solid-State Batteries: Substantial Deterioration of ASSBs Can Occur After High-Temperature Storage


New technical paper titled “Detrimental effect of high-temperature storage on sulfide-based all-solid-state batteries” was just published by researchers at Seoul National University, National Synchrotron Radiation Research Center (Taiwan), and Battery Material Lab at the Samsung Advanced Institute of Technology.

According to this AIP article, “The team found storage as low as 70 degrees Celsius can induce decomposition when the electrolyte is in contact with oxide cathode materials. That degradation creates a nonideal, porous cathode-electrolyte interface, leading to large interfacial resistance and a dramatic reduction in battery performance.”
