Title: Structural manipulation approaches towards enhanced sodium ionic conductivity in Na-rich antiperovskites

Abstract

High-performance solid electrolytes are critical for realizing all-solid-state batteries with enhance safety and cycling efficiency. However, currently available candidates (sulfides and the NASICON-typ ceramics) still suffer from drawbacks such as inflammability, high-cost and unfavorable machinability Here we present the structural manipulation approaches to improve the sodium ionic conductivity in series of affordable Na-rich antiperovskites. Experimentally, the whole solid solutions of Na₃OX (X ¼ Cl Br, I) are synthesized via a facile and timesaving route from the cheapest raw materials (Na, NaOH an NaX). The materials are nonflammable, suitable for thermoplastic processing due to low melting temperature (<300° C) without decomposing. Notably, owing to the flexibility of perovskite-type structure it's feasible to control the local structure features by means of size-mismatch substitution an unequivalent-doping for a favorable sodium ionic diffusion pathway. Enhancement of sodium ioni conductivity by 2 magnitudes is demonstrated by these chemical tuning methods. The optimized sodiu ionic conductivity in Na_2.9Sr_0.05OBr_0.6I_0.4 bulk samples reaches 1.9 10^{- 3} S/cm at 200° C and even highe at elevated temperature. Here, we believe further chemical tuning efforts on Na-rich antiperovskites wil promote their performance greatly for practical all-solid state battery applications.

Sodium ion transport mechanisms in antiperovskite electrolytes Na₃OBr and Na₄OI₂: An in Situ neutron diffraction study

Journal Article Zhu, Jinlong ; Wang, Yonggang ; Li, Shuai ; ... - Inorganic Chemistry

Na-rich antiperovskites are recently developed solid electrolytes with enhanced sodium ionic conductivity and show promising functionality as a novel solid electrolyte in an all solid-stat battery. In this work, the sodium ionic transport pathways of the parent compound Na₃OBr, as well as the modified layered antiperovskite Na₄OI₂, were studied and compared through temperature dependent neutron diffraction combined with the maximum entropy method. In the cubic Na₃OBr antiperovskite, the nuclear density distribution maps at 500 K indicate that sodium ions ho within and among oxygen octahedra, and Br^- ions are not involved in the tetragonal Na₄OI₂ antiperovskite, Na ions, which connectmore »« less

Enhanced ionic conductivity with Li₇O₂Br₃ phase in Li₃OBr anti-perovskite solid electrolyte

Journal Article Zhu, Jinlong ; Li, Shuai ; Zhang, Yi ; ... - Applied Physics Letters

Here, cubic anti-perovskites with general formula Li₃OX (X = Cl, Br, I) were recently reported as superionic conductors with the potential for use as solid electrolytes in all-solid-state lithium ion batteries. These electrolytes are nonflammable, low-cost and suitable for thermoplastic processing. However, the primary obstacle of its practical implementation is the relatively low ionic conductivity at room temperature. In this work, we synthesized a composite material consisting of two anti-perovskite phases, namely cubic Li₃OBr and layered Li₇O₂Br₃, by solid state reaction routes. The results indicate that with the phase fraction of Li₇O₂Br₃ increasing to 44 wt %, the ionic conductivitymore »« less

The structure stability under high pressure and thermal expansion behavior of Na₃OBr and Na₄OI₂, two prototypes of alkali-metal-rich antiperovskites, were investigated by in situ synchrotron X-ray diffraction techniques under high pressure and low temp. Both are soft materials with bulk modulus of 58.6 GPa and 52.0 GPa for Na₃OBr and Na₄OI₂, resp. The cubic Na₃OBr structure and tetragonal Na₄OI₂ with intergrowth K₂NiF₄ structure are stable under high pressure up to 23 GPa. Although being a characteristic layered structure, Na₄OI₂ exhibits nearly isotropic compressibility.

Antiperovskite Superionic Conductors: A Critical Review

Journal Article Zheng, Jingfeng ; Perry, Brian ; Wu, Yiying - ACS Materials Au

Antiperovskites of composition M₃AB (M = Li, Na, K; A = O; B = Cl, Br, I, NO₂, etc.) have recently been investigated as solid-state electrolytes for all-solid-state batteries. Inspired by the impressive ionic conductivities of Li₃OCl_0.5Br_0.5 and Na₃OBH₄ as high as 10^–3 S/cm at room temperature, many variants of antiperovskite-based Li-ion and Na-ion conductors have been reported, and K-ion antiperovskites are emerging. These materials exhibit low melting points and thus have the advantages of easy processing into films and intimate contacts with electrodes. However, there are also issues in interpreting the stellar materials and reproducing their high ionic conductivities.more »« less
