Materials Data on Ni10SnP3 by Materials Project

Abstract

Ni10SnP3 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are seven inequivalent Ni sites. In the first Ni site, Ni is bonded in a 3-coordinate geometry to three equivalent P atoms. All Ni–P bond lengths are 2.29 Å. In the second Ni site, Ni is bonded in a distorted bent 150 degrees geometry to two equivalent Sn and two equivalent P atoms. Both Ni–Sn bond lengths are 2.87 Å. Both Ni–P bond lengths are 2.25 Å. In the third Ni site, Ni is bonded in a 3-coordinate geometry to one Ni, one Sn, and three P atoms. The Ni–Ni bond length is 2.51 Å. The Ni–Sn bond length is 2.61 Å. There are two shorter (2.20 Å) and one longer (2.29 Å) Ni–P bond lengths. In the fourth Ni site, Ni is bonded in a 2-coordinate geometry to one Ni, two Sn, and two equivalent P atoms. The Ni–Ni bond length is 2.78 Å. There are one shorter (2.65 Å) and one longer (3.03 Å) Ni–Sn bond lengths. Both Ni–P bond lengths are 2.29 Å. In the fifth Ni site, Ni is bonded in a 3-coordinate geometry to one Ni, one Sn, and three P atoms. The Ni–Ni bond length is 2.72 Å. The Ni–Sn bond length is 2.61 Å. There are two shorter (2.27 Å) and one longer (2.31 Å) Ni–P bond lengths. In the sixth Ni site, Ni is bonded in a 4-coordinate geometry to nine Ni, one Sn, and three equivalent P atoms. The Ni–Sn bond length is 2.54 Å. All Ni–P bond lengths are 2.40 Å. In the seventh Ni site, Ni is bonded in a 4-coordinate geometry to one Sn and three equivalent P atoms. The Ni–Sn bond length is 2.45 Å. All Ni–P bond lengths are 2.36 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a cuboctahedral geometry to twelve Ni atoms. In the second Sn site, Sn is bonded in a 5-coordinate geometry to fourteen Ni atoms. There are two inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to nine Ni atoms. In the second P site, P is bonded in a body-centered cubic geometry to eight Ni atoms.

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.
