High-performance superelastic materials with a combination of high stress, large elastic recovery strain, and stable modulus over wide temperature range are highly desired for variety technological applications. Unfortunately, it is difficult to achieve these multi-functionalities simultaneously because most have encounter the softening effect limited whereas Elinvar-type show small strain limit. Here, we report (TiZrHf)44Ni25Cu15Co10Nb6 high-entropy alloy that meets all requirements. This...
Iron-based phosphate materials have been employed as cathodes for sodium-ion batteries (SIBs) because of their low cost and environmental friendliness, but the electrochemical performance this kind cathode is far from that a practical application.
