Abstract

Ba5MgV4Mn(O7Cl3)2 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to seven O2- and four Cl1- atoms. There are a spread of Ba–O bond distances ranging from 2.77–3.27 Å. There are a spread of Ba–Cl bond distances ranging from 3.23–3.41 Å. In the second Ba2+ site, Ba2+ is bonded to four O2- and eight Cl1- atoms to form distorted BaCl8O4 cuboctahedra that share corners with two equivalent MnCl6 octahedra, edges with two equivalent BaCl8O4 cuboctahedra, edges with two equivalent VO4 tetrahedra, and faces with two equivalent MnCl6 octahedra. The corner-sharing octahedral tilt angles are 27°. There are two shorter (2.92 Å) and two longer (2.97 Å) Ba–O bond lengths. There are a spread of Ba–Cl bond distances ranging from 3.36–3.51 Å. In the third Ba2+ site, Ba2+ is bonded in a 11-coordinate geometry to seven O2- and four Cl1- atoms. There are a spread of Ba–O bond distances ranging from 2.74–3.29 Å. There are a spread of Ba–Cl bond distances ranging from 3.22–3.39 Å. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six VO4 tetrahedra. There are a spread of Mg–O bond distances ranging from 2.05–2.26 Å. There are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one MgO6 octahedra, a cornercorner with one VO4 tetrahedra, and an edgeedge with one BaCl8O4 cuboctahedra. The corner-sharing octahedral tilt angles are 20°. There are a spread of V–O bond distances ranging from 1.71–1.84 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with two equivalent MgO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedral tilt angles are 43°. There are a spread of V–O bond distances ranging from 1.69–1.82 Å. Mn2+ is bonded to six Cl1- atoms to form MnCl6 octahedra that share corners with two equivalent BaCl8O4 cuboctahedra and faces with two equivalent BaCl8O4 cuboctahedra. There are a spread of Mn–Cl bond distances ranging from 2.51–2.58 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent Ba2+ and two V5+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two Ba2+ and one V5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one V5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Ba2+, one Mg2+, and one V5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ba2+, one Mg2+, and one V5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one V5+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to two Ba2+, one Mg2+, and one V5+ atom. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four Ba2+ and one Mn2+ atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to four Ba2+ and one Mn2+ atom.

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.
