Unveiling the High‐Voltage Reactivity and Gas Evolution With Aluminum‐Based Chloride and Oxychloride Catholytes in Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The work examines the electrochemical and interfacial behaviors of crystalline NaAlCl4 and amorphous Na–Al–oxychloride solid electrolytes with NaNi0.5Mn0.5O2 cathodes. Operando gas evolution and ToF‐SIMS analyses highlight that pure chloride solid electrolytes offer greater interfacial stability and safety compared to the oxychloride solid electrolytes

Interannealing twin-roll cast Al–Fe–Si strips without homogenization

open access: yesScripta Materialia, 2009
When annealed without homogenization, a twin-roll cast Al–1Fe–0.2Si strip undergoes precipitation of αc particles below 200 °C, dissolution of primary Al6Fe and further precipitation of αc particles above 350 °C. Recrystallization and then recovery processes are superimposed on this reaction sequence when the cast strip is cold rolled before thermal ...

Homogenization of a twin-roll cast thin Al–Mn strip

open access: yesJournal of Alloys and Compounds, 2009
Abstract A sound homogenization practice was investigated for thin Al–Mn strips. The structure in the as-cast state reveals features typical of rapid solidification. The impact of subsequent hot rolling of the just solidified strip in the caster roll gap is also evident.

Scalable High‐Force Zipping Electrostatic Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.
