900°C thermal-force coupling carbonization tailoring hard carbon microstructures enables high performance sodium-ion pouch batteries

Abstract Hard carbon materials are promising candidates for advancing large-scale energy storage in sodium-ion batteries. However, a fundamental trade-off often exists between sodium storage sites and fast diffusion kinetics in hard carbon. Herein, we overturn this long-standing...

Evolution and Manipulation of Interstitial Oxygen Configuration in Titanium—A Review

Oxygen has been regarded as a detrimental impurity in titanium alloys, as it triggers embrittlement and compromises ductility. Recent research advancements, however, have revolutionized this perception, revealing oxygen as a powerful microstructural architect capable of mediating...
