Materials Data on CuAg10(PbO4)3 by Materials Project

Abstract

Ag10Cu(PbO4)3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are five inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.13 Å) and one longer (2.15 Å) Ag–O bond lengths. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.13 Å) and one longer (2.16 Å) Ag–O bond lengths. In the third Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.13 Å) and one longer (2.15 Å) Ag–O bond lengths. In the fourth Ag1+ site, Ag1+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.28–2.33 Å. In the fifth Ag1+ site, Ag1+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.28–2.33 Å. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share edges with three PbO6 octahedra. There are a spread of Cu–O bond distances ranging from 2.07–2.11 Å. There are three inequivalent Pb4+ sites. In the first Pb4+ site, Pb4+ is bonded to six O2- atoms to form edge-sharing PbO6 octahedra. There are two shorter (2.24 Å) and four longer (2.25 Å) Pb–O bond lengths. In the second Pb4+ site, Pb4+ is bonded to six O2- atoms to form PbO6 octahedra that share an edgeedge with one PbO6 octahedra and edges with two equivalent CuO6 octahedra. There are a spread of Pb–O bond distances ranging from 2.23–2.30 Å. In the third Pb4+ site, Pb4+ is bonded to six O2- atoms to form PbO6 octahedra that share an edgeedge with one CuO6 octahedra and edges with two equivalent PbO6 octahedra. There are a spread of Pb–O bond distances ranging from 2.21–2.28 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two Ag1+, one Cu2+, and one Pb4+ atom to form OCuAg2Pb tetrahedra that share corners with eleven OAg2Pb2 tetrahedra and an edgeedge with one OCuAg2Pb tetrahedra. In the second O2- site, O2- is bonded to two Ag1+ and two Pb4+ atoms to form OAg2Pb2 tetrahedra that share corners with eleven OCuAg2Pb tetrahedra and an edgeedge with one OAg2Pb2 tetrahedra. In the third O2- site, O2- is bonded to two Ag1+, one Cu2+, and one Pb4+ atom to form a mixture of corner and edge-sharing OCuAg2Pb tetrahedra. In the fourth O2- site, O2- is bonded to two Ag1+ and two Pb4+ atoms to form OAg2Pb2 tetrahedra that share corners with eleven OCuAg2Pb tetrahedra and an edgeedge with one OAg2Pb2 tetrahedra. In the fifth O2- site, O2- is bonded to two Ag1+, one Cu2+, and one Pb4+ atom to form a mixture of corner and edge-sharing OCuAg2Pb tetrahedra. In the sixth O2- site, O2- is bonded to two Ag1+ and two Pb4+ atoms to form OAg2Pb2 tetrahedra that share corners with eleven OCuAg2Pb tetrahedra and an edgeedge with one OAg2Pb2 tetrahedra.

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.
