Materials Data on DyGaFeCo3 by Materials Project

Abstract

DyFeCo3Ga crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. Dy is bonded in a 6-coordinate geometry to four equivalent Fe, ten Co, and four equivalent Ga atoms. All Dy–Fe bond lengths are 3.21 Å. There are a spread of Dy–Co bond distances ranging from 2.88–3.24 Å. All Dy–Ga bond lengths are 3.17 Å. Fe is bonded to four equivalent Dy, six Co, and two equivalent Ga atoms to form distorted FeDy4Ga2Co6 cuboctahedra that share corners with four equivalent CoDy4Ga2Fe2Co4 cuboctahedra, corners with four equivalent GaDy4Fe2Co6 cuboctahedra, corners with eight equivalent FeDy4Ga2Co6 cuboctahedra, edges with two equivalent FeDy4Ga2Co6 cuboctahedra, edges with four equivalent CoDy4Ga2Fe2Co4 cuboctahedra, edges with four equivalent GaDy4Fe2Co6 cuboctahedra, faces with two equivalent FeDy4Ga2Co6 cuboctahedra, faces with four equivalent CoDy4Ga2Fe2Co4 cuboctahedra, and faces with four equivalent GaDy4Fe2Co6 cuboctahedra. There are four shorter (2.45 Å) and two longer (2.46 Å) Fe–Co bond lengths. Both Fe–Ga bond lengths are 2.54 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to three equivalent Dy, two equivalent Fe, two equivalent Co, and two equivalent Ga atoms. Both Co–Co bond lengths are 2.44 Å. Both Co–Ga bond lengths are 2.53 Å. In the second Co site, Co is bonded to four equivalent Dy, two equivalent Fe, four equivalent Co, and two equivalent Ga atoms to form distorted CoDy4Ga2Fe2Co4 cuboctahedra that share corners with four equivalent FeDy4Ga2Co6 cuboctahedra, corners with four equivalent GaDy4Fe2Co6 cuboctahedra, corners with eight equivalent CoDy4Ga2Fe2Co4 cuboctahedra, edges with two equivalent CoDy4Ga2Fe2Co4 cuboctahedra, edges with four equivalent FeDy4Ga2Co6 cuboctahedra, edges with four equivalent GaDy4Fe2Co6 cuboctahedra, faces with two equivalent CoDy4Ga2Fe2Co4 cuboctahedra, faces with four equivalent FeDy4Ga2Co6 cuboctahedra, and faces with four equivalent GaDy4Fe2Co6 cuboctahedra. Both Co–Ga bond lengths are 2.51 Å. Ga is bonded to four equivalent Dy, two equivalent Fe, and six Co atoms to form GaDy4Fe2Co6 cuboctahedra that share corners with four equivalent FeDy4Ga2Co6 cuboctahedra, corners with four equivalent CoDy4Ga2Fe2Co4 cuboctahedra, corners with eight equivalent GaDy4Fe2Co6 cuboctahedra, edges with two equivalent GaDy4Fe2Co6 cuboctahedra, edges with four equivalent FeDy4Ga2Co6 cuboctahedra, edges with four equivalent CoDy4Ga2Fe2Co4 cuboctahedra, faces with two equivalent GaDy4Fe2Co6 cuboctahedra, faces with four equivalent FeDy4Ga2Co6 cuboctahedra, and faces with four equivalent CoDy4Ga2Fe2Co4 cuboctahedra.

Cyclic moisture reactivation of calcium sorbents for long duration thermochemical energy storage

The transition to a flexible and reliable energy infrastructure, using electro-thermal energy generation technologies such as geothermal, concentrated solar power, and nuclear, usually demands simultaneous advancement of thermal energy storage (TES) to support on-demand electricity generation and industrial applications while mitigating the inherent intermittency of renewable energy sources and power outages from direct energy generation. Among TES technologies, thermochemical energy storage (TCES) based on calcium looping emerges as a compelling high-power energy storage candidate due to its high reaction enthalpy, compatibility with elevated operating temperatures, and abundance of low-cost materials. However, the long-term durability of calcium-based sorbents for TCES is hindered by surface sintering and particle aggregation, leading to performance degradation over repeated thermal cycles. This study explores a moisture hydration-based strategy to regenerate a degraded calcium sorbent and mitigate performance degradation for long duration TCES. The addition of moisture transforms calcium oxide into calcium hydroxide and produces intercalation water layers, associated with a regenerated surface area and reduced calcium oxide crystallite size. Both these effects are beneficial in restoring the sorbents' reactivity for carbonization. Additionally, an optimized hydration-assisted reactivation protocol balances the recovered energy storage capacity with heating penalty required for moisture removal from hydrated samples, resulting in an enhanced energy storage capacity up to 176% compared to benchmark sorbents that undergo cycling without reactivation after 60 cycles. In conclusion, these results highlight the potential of hydration-assisted reactivation to enhance the long-term performance of TCES, providing an effective pathway to advancing electro-thermal storage technologies.
