Materials Data on LiInI4 by Materials Project

Abstract

LiInI4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded to six I1- atoms to form LiI6 octahedra that share corners with two equivalent LiI6 octahedra, corners with two equivalent InI4 tetrahedra, an edgeedge with one LiI6 octahedra, and edges with two equivalent InI4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of Li–I bond distances ranging from 2.90–3.30 Å. In3+ is bonded to four I1- atoms to form InI4 tetrahedra that share corners with two equivalent LiI6 octahedra and edges with two equivalent LiI6 octahedra. The corner-sharing octahedra tilt angles range from 62–64°. There are a spread of In–I bond distances ranging from 2.74–2.80 Å. There are four inequivalent I1- sites. In the first I1- site, I1- is bonded in an L-shaped geometry to one Li1+ and one In3+ atom. In the second I1- site, I1- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one In3+ atom. In the third I1- site, I1- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one In3+ atom. In the fourth I1- site, I1- is bonded in a bent 120 degrees geometry to one Li1+ and one In3+ 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.
