Materials Data on Ce2VCo16 by Materials Project

Abstract

Ce2VCo16 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 1-coordinate geometry to one V and nineteen Co atoms. The Ce–V bond length is 3.05 Å. There are a spread of Ce–Co bond distances ranging from 2.85–3.21 Å. In the second Ce site, Ce is bonded in a 12-coordinate geometry to eighteen Co atoms. There are a spread of Ce–Co bond distances ranging from 2.93–3.30 Å. V is bonded in a 1-coordinate geometry to one Ce and thirteen Co atoms. There are a spread of V–Co bond distances ranging from 2.25–2.67 Å. There are twelve inequivalent Co sites. In the first Co site, Co is bonded to two equivalent Ce and ten Co atoms to form CoCe2Co10 cuboctahedra that share corners with fourteen CoCe2V2Co8 cuboctahedra, edges with six CoCe3Co9 cuboctahedra, and faces with ten CoCe2Co10 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.40–2.56 Å. In the second Co site, Co is bonded to two equivalent Ce and ten Co atoms to form CoCe2Co10 cuboctahedra that share corners with fourteen CoCe2V2Co8 cuboctahedra, edges with six CoCe3Co9 cuboctahedra, and faces with ten CoCe2Co10 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.40–2.57 Å. In the third Co site, Co is bonded to two equivalent Ce, two equivalent V, and eight Co atoms to form distorted CoCe2V2Co8 cuboctahedra that share corners with fourteen CoCe2Co10 cuboctahedra, edges with six CoCe3Co9 cuboctahedra, and faces with ten CoCe2Co10 cuboctahedra. There are four shorter (2.39 Å) and four longer (2.41 Å) Co–Co bond lengths. In the fourth Co site, Co is bonded to two equivalent Ce, two equivalent V, and eight Co atoms to form distorted CoCe2V2Co8 cuboctahedra that share corners with fourteen CoCe2Co10 cuboctahedra, edges with six CoCe3Co9 cuboctahedra, and faces with ten CoCe2Co10 cuboctahedra. There are four shorter (2.39 Å) and four longer (2.41 Å) Co–Co bond lengths. In the fifth Co site, Co is bonded in a 2-coordinate geometry to one Ce, one V, and twelve Co atoms. There are three shorter (2.62 Å) and six longer (2.68 Å) Co–Co bond lengths. In the sixth Co site, Co is bonded in a 12-coordinate geometry to two Ce, one V, and nine Co atoms. There are a spread of Co–Co bond distances ranging from 2.36–2.56 Å. In the seventh Co site, Co is bonded in a 12-coordinate geometry to two Ce, one V, and nine Co atoms. There are a spread of Co–Co bond distances ranging from 2.36–2.56 Å. In the eighth Co site, Co is bonded in a 12-coordinate geometry to two Ce, one V, and nine Co atoms. There are a spread of Co–Co bond distances ranging from 2.51–2.56 Å. In the ninth Co site, Co is bonded to three Ce and nine Co atoms to form a mixture of distorted corner, edge, and face-sharing CoCe3Co9 cuboctahedra. Both Co–Co bond lengths are 2.43 Å. In the tenth Co site, Co is bonded to three Ce and nine Co atoms to form a mixture of distorted corner, edge, and face-sharing CoCe3Co9 cuboctahedra. In the eleventh Co site, Co is bonded to three Ce, one V, and eight Co atoms to form distorted CoCe3VCo8 cuboctahedra that share corners with fifteen CoCe2Co10 cuboctahedra, edges with eight CoCe2Co10 cuboctahedra, and faces with ten CoCe2V2Co8 cuboctahedra. There are one shorter (2.47 Å) and one longer (2.48 Å) Co–Co bond lengths. In the twelfth Co site, Co is bonded to three Ce, one V, and eight Co atoms to form distorted CoCe3VCo8 cuboctahedra that share corners with fifteen CoCe2Co10 cuboctahedra, edges with eight CoCe2Co10 cuboctahedra, and faces with ten CoCe2V2Co8 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.
