Abstract

Re2Te4OCl22 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Re2Te4OCl22 clusters. Re7+ is bonded to one O2- and five Cl1- atoms to form ReCl5O octahedra that share a cornercorner with one ReCl5O octahedra and corners with four TeCl5 square pyramids. The corner-sharing octahedral tilt angles are 0°. The Re–O bond length is 1.86 Å. There are a spread of Re–Cl bond distances ranging from 2.31–2.44 Å. There are two inequivalent Te+2.50+ sites. In the first Te+2.50+ site, Te+2.50+ is bonded to five Cl1- atoms to form distorted TeCl5 square pyramids that share corners with two equivalent ReCl5O octahedra. The corner-sharing octahedra tilt angles range from 74–77°. There are a spread of Te–Cl bond distances ranging from 2.33–3.10 Å. In the second Te+2.50+ site, Te+2.50+ is bonded to five Cl1- atoms to form TeCl5 square pyramids that share corners with two equivalent ReCl5O octahedra. The corner-sharing octahedra tilt angles range from 75–80°. There are a spread of Te–Cl bond distances ranging from 2.33–2.92 Å. O2- is bonded in a linear geometry to two equivalent Re7+ atoms. There are eleven inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Re7+ and one Te+2.50+ atom. In the second Cl1- site, Cl1- is bonded in a distorted water-like geometry to one Re7+ and one Te+2.50+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Te+2.50+ atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Te+2.50+ atom. In the fifth Cl1- site, Cl1- is bonded in a single-bond geometry to one Re7+ atom. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one Te+2.50+ atom. In the seventh Cl1- site, Cl1- is bonded in a distorted water-like geometry to one Re7+ and one Te+2.50+ atom. In the eighth Cl1- site, Cl1- is bonded in a single-bond geometry to one Te+2.50+ atom. In the ninth Cl1- site, Cl1- is bonded in a single-bond geometry to one Te+2.50+ atom. In the tenth Cl1- site, Cl1- is bonded in a single-bond geometry to one Te+2.50+ atom. In the eleventh Cl1- site, Cl1- is bonded in a distorted water-like geometry to one Re7+ and one Te+2.50+ 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.
