Materials Data on InClO by Materials Project

InOCl crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one InOCl sheet oriented in the (0, 0, 1) direction. In3+ is bonded to four equivalent O2- and two equivalent Cl1- atoms to form a mixture of distorted edge and corner-sharing InCl2O4 octahedra. The corner-sharing octahedral tilt angles are 34°. There are two shorter (2.17 Å) and two longer (2.26 Å) In–O bond lengths. Both In–Cl bond lengths are 2.55 Å. O2- is bonded to four equivalent In3+ atoms to form a mixture of distorted edge and corner-sharing OIn4 tetrahedra. Cl1- is bonded in an L-shaped geometry to two equivalent In3+ atoms.

Deciphering Chemical/Electrochemical Compatibility of Li 3 InCl 6 in 5.2 V High-Voltage LiCoO 2 All-Solid-State Batteries

Large interfacial resistance is a widely recognized impediment to the advancement of high-voltage, all-solid-state batteries. However, a comprehensive understanding of the fundamental cause behind the interfacial resistance between solid electrolytes and typical layered oxide cathodes has not yet been achieved. Here, we investigated the high-voltage stability of Li 3 InCl 6 and elucidated the underlying interfacial electrochemical reactions between LiCoO 2 and Li 3 InCl 6 . Further, the pairing of Li 3 InCl 6 with LiCoO 2 exhibited a superior capacity retention of 73.6% even at 5.2 V, much higher than 28.2% charged at 4.6 V in lithium-ion batteries after 70 cycles. The enhanced high-voltage stability of ASSBs is attributed to the stable interface formed between LiCoO 2 and Li 3 InCl 6 and the reinforced surface and bulk structure stability. On the other hand, the ultrahigh voltage still causes the partial decomposition of Li 3 InCl 6 and generates interfacial compounds such as InClO and cobalt and indium chlorides/oxides.
