  "textContent": "Up to now, it has only been possible to deduce indirectly why high-temperature batteries lose efficiency and durability while in use. For the first time, a team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has now used operando X-ray radiography to look directly into a sodium-zinc molten salt battery at approximately 600 degrees Celsius.",
