  Record stack durability in industrial solid oxide steam electrolysis through operational control

  Here, we show that long-term stack durability can be strongly influenced by operating strategy, achieving 25,000 h of steam electrolysis operation in a full 70-cell solid oxide electrolysis cell stack under frequency-dependent electrochemical operation (AC:DC).

  Conformal oxides decouple chemical stability and energetics at NiO x /perovskite interfaces

  This synergy yielded high efficiency in perovskite photovoltaic devices and showed an ~10x improvement in T 90 lifetime in open-circuit conditions under AM1.5G at 65°C.

  Unlocking cycle life of lithium metal batteries

  Here, we reveal that electrolyte depletion caused by unstable solid electrolyte interphases (SEIs) leads to electrolyte dry-out and induces lithium compensation through anode-to-cathode cross-talk, whereby soluble anionic species formed at the anode migrate to the cathode and release Li + from electrolyte salts upon oxidation.
