  "textContent": "Although solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from TU Wien, Humboldt-University Berlin and HZB has now analyzed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. The research is published in the journal ACS Energy Letters.",
