Abstract Scope Solid-liquid phase change materials require engineering measures in the form of encapsulants and fin structures to provide mechanical support, prevent liquid phase leakage, and enhance thermal conductivity. We report here the use of Additively Manufactured NiTi and NiTi-based shape memory alloys (SMAs) as ultrahigh performance metallic solid-state PCMs. This development will allow the fabrication of complex thermal designs and topology optimization schemes without the design constraints imposed by standard PCMs and traditional manufacturing processes. In addition to design freedom, this newly-identified class of metallic PCM offers a two-order-of-magnitude figure-of-merit improvement over traditional PCMs with excellent tunability, both through additive process parameters and post-processing heat treatment. The ultrahigh performance of reversible martensitic transformations in NiTi-based alloys, in conjunction with its excellent structural properties and additive manufacturability presents an opportunity for a combination of innovative materials science, thermal engineering, and AM solutions to meet the extreme demands of emerging energy storage systems.
