Negative‐Thermal‐Expansion Strategy Enables Hard Carbon With Tuned Heat/Strain Tolerances for Sodium Storage

ABSTRACT The thermal/stress runaways pose a risk to the safety and industrialization of sodium‐ion battery (SIB), which hence requires external management equipment. Actually, the thermal/stress generation originates from the repetitive Na + intercalation within carbon interlayer...

Robust Ferroelectricity in Chalcogenides Down to 2 nm Particles

ABSTRACT Nano‐ferroelectric materials are essential for advancing miniaturized energy converters, optoelectronics, and nonvolatile memory devices. However, the depolarizing fields of size‐reduced nanoparticles will weaken or even eliminate the ferroelectric spontaneous polarizati...
