Materials Data on InGaSnO5 by Materials Project

Abstract

InGaSnO5 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with two equivalent SnO6 octahedra, corners with five GaO4 tetrahedra, and edges with four InO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of In–O bond distances ranging from 2.11–2.31 Å. In the second In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with four equivalent SnO6 octahedra, corners with three GaO4 tetrahedra, and edges with four InO6 octahedra. The corner-sharing octahedra tilt angles range from 51–54°. There are a spread of In–O bond distances ranging from 2.11–2.30 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with three InO6 octahedra, corners with four SnO6 octahedra, and corners with two equivalent GaO4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–65°. There are a spread of Ga–O bond distances ranging from 1.87–1.91 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with two equivalent SnO6 octahedra, corners with five InO6 octahedra, and corners with two equivalent GaO4 tetrahedra. The corner-sharing octahedra tilt angles range from 56–69°. There are a spread of Ga–O bond distances ranging from 1.87–1.90 Å. There are three inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with four equivalent InO6 octahedra, corners with four equivalent GaO4 tetrahedra, and edges with two equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are two shorter (2.02 Å) and four longer (2.14 Å) Sn–O bond lengths. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with four equivalent SnO6 octahedra, corners with four equivalent GaO4 tetrahedra, and edges with two equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are four shorter (2.10 Å) and two longer (2.15 Å) Sn–O bond lengths. In the third Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with two equivalent SnO6 octahedra, corners with four equivalent InO6 octahedra, corners with two equivalent GaO4 tetrahedra, and edges with two equivalent SnO6 octahedra. The corner-sharing octahedra tilt angles range from 51–54°. There are a spread of Sn–O bond distances ranging from 2.04–2.14 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one In3+ and two equivalent Sn4+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to three Sn4+ atoms. In the third O2- site, O2- is bonded to three In3+ and one Ga3+ atom to form a mixture of distorted edge and corner-sharing OIn3Ga tetrahedra. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ga3+ and two equivalent Sn4+ atoms. In the fifth O2- site, O2- is bonded to three In3+ and one Ga3+ atom to form a mixture of distorted edge and corner-sharing OIn3Ga tetrahedra. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent In3+ and one Sn4+ atom. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to two equivalent In3+ and one Sn4+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ga3+ and two equivalent Sn4+ atoms. In the ninth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Ga3+ and one Sn4+ atom. In the tenth O2- site, O2- is bonded in a trigonal planar geometry to one In3+ and two equivalent Ga3+ atoms.

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.
