Abstract

Ta2Te4OBr10 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Ta2Te4OBr10 cluster. Ta4+ is bonded to one O2- and five Br1- atoms to form distorted corner-sharing TaBr5O octahedra. The corner-sharing octahedral tilt angles are 0°. The Ta–O bond length is 1.90 Å. There are a spread of Ta–Br bond distances ranging from 2.49–2.70 Å. There are two inequivalent Te1+ sites. In the first Te1+ site, Te1+ is bonded in a single-bond geometry to one Br1- atom. The Te–Br bond length is 3.19 Å. In the second Te1+ site, Te1+ is bonded in a single-bond geometry to one Br1- atom. The Te–Br bond length is 3.41 Å. O2- is bonded in a linear geometry to two equivalent Ta4+ atoms. There are five inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted bent 120 degrees geometry to one Ta4+ and one Te1+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Ta4+ atom. In the third Br1- site, Br1- is bonded in a single-bond geometry to one Ta4+ and one Te1+ atom. In the fourth Br1- site, Br1- is bonded in a single-bond geometry to one Ta4+ atom. In the fifth Br1- site, Br1- is bonded in a single-bond geometry to one Ta4+ 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.
