Materials Data on Tl2Cl3 by Materials Project

Abstract

TlTlCl3 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of thirty-two thallium molecules and two TlCl3 ribbons oriented in the (1, 0, 0) direction. In each TlCl3 ribbon, there are five inequivalent Tl sites. In the first Tl site, Tl is bonded in a 2-coordinate geometry to five Cl atoms. There are a spread of Tl–Cl bond distances ranging from 3.14–3.30 Å. In the second Tl site, Tl is bonded in an octahedral geometry to six Cl atoms. There are a spread of Tl–Cl bond distances ranging from 2.58–2.71 Å. In the third Tl site, Tl is bonded in a 1-coordinate geometry to one Cl atom. The Tl–Cl bond length is 3.12 Å. In the fourth Tl site, Tl is bonded in an octahedral geometry to six Cl atoms. There are a spread of Tl–Cl bond distances ranging from 2.61–2.69 Å. In the fifth Tl site, Tl is bonded in an octahedral geometry to six Cl atoms. There are a spread of Tl–Cl bond distances ranging from 2.55–2.74 Å. There are fifteen inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted single-bond geometry to one Tl atom. In the second Cl site, Cl is bonded in a single-bond geometry to two Tl atoms. In the third Cl site, Cl is bonded in a single-bond geometry to three Tl atoms. In the fourth Cl site, Cl is bonded in a distorted single-bond geometry to two Tl atoms. In the fifth Cl site, Cl is bonded in a single-bond geometry to one Tl atom. In the sixth Cl site, Cl is bonded in a single-bond geometry to one Tl atom. In the seventh Cl site, Cl is bonded in a 3-coordinate geometry to three Tl atoms. In the eighth Cl site, Cl is bonded in a distorted single-bond geometry to one Tl atom. In the ninth Cl site, Cl is bonded in a single-bond geometry to one Tl atom. In the tenth Cl site, Cl is bonded in a linear geometry to two Tl atoms. In the eleventh Cl site, Cl is bonded in a single-bond geometry to one Tl atom. In the twelfth Cl site, Cl is bonded in a single-bond geometry to one Tl atom. In the thirteenth Cl site, Cl is bonded in a single-bond geometry to three Tl atoms. In the fourteenth Cl site, Cl is bonded in a single-bond geometry to one Tl atom. In the fifteenth Cl site, Cl is bonded in a single-bond geometry to one Tl 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.
