Abstract

(Ir)2InBr4(Te)7(Te2Br3)2(TeBr2)3 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four iridium molecules, fourteen tellurium molecules, two InBr4 clusters, two Te2Br3 clusters, and two TeBr2 clusters. In each InBr4 cluster, In3+ is bonded in a tetrahedral geometry to four Br1- atoms. There are a spread of In–Br bond distances ranging from 2.54–2.57 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the third Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one In3+ atom. In each Te2Br3 cluster, there are four inequivalent Te+0.29+ sites. In the first Te+0.29+ site, Te+0.29+ is bonded in a 1-coordinate geometry to one Br1- atom. The Te–Br bond length is 3.39 Å. In the second Te+0.29+ site, Te+0.29+ is bonded in a distorted single-bond geometry to one Br1- atom. The Te–Br bond length is 3.45 Å. In the third Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.64–2.98 Å. In the fourth Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.64–2.98 Å. There are six inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to three Te+0.29+ atoms. In the third Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the fourth Br1- site, Br1- is bonded in a 2-coordinate geometry to three Te+0.29+ atoms. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the sixth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In each TeBr2 cluster, there are three inequivalent Te+0.29+ sites. In the first Te+0.29+ site, Te+0.29+ is bonded in a single-bond geometry to one Br1- atom. The Te–Br bond length is 3.33 Å. In the second Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are two shorter (2.67 Å) and two longer (2.94 Å) Te–Br bond lengths. In the third Te+0.29+ site, Te+0.29+ is bonded in a rectangular see-saw-like geometry to four Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.64–3.03 Å. There are six inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to two Te+0.29+ atoms. In the third Br1- site, Br1- is bonded in a 3-coordinate geometry to three Te+0.29+ atoms. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ atom. In the sixth Br1- site, Br1- is bonded in a single-bond geometry to one Te+0.29+ 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.
