The interlaboratory comparability and reproducibility of all-solid-state battery cell cycling performance are poorly understood due to the lack of standardized set-ups and assembly parameters. This study quantifies the extent of this variability by providing commercially sourced battery materials—LiNi_0.6Mn_0.2Co_0.2O₂ for the positive electrode, Li₆PS₅Cl as the solid electrolyte and indium for the negative electrode—to 21 research groups. Each group was asked to use their own cell assembly protocol but follow a specific electrochemical protocol. The results show large variability in assembly and electrochemical performance, including differences in processing pressures, pressing durations and In-to-Li ratios. Despite this, an initial open circuit voltage of 2.5 and 2.7 V vs Li⁺/Li is a good predictor of successful cycling for cells using these electroactive materials. We suggest a set of parameters for reporting all-solid-state battery cycling results and advocate for reporting data in triplicate.

由于缺乏标准化的设置和组装参数，人们对全固态电池循环性能的实验室间可比性和再现性知之甚少。这项研究通过向 21 个研究小组提供商用电池材料（正极为 LiNi _0.6 Mn _0.2 Co _0.2 O ₂ 、固体电解质为 Li ₆ PS ₅ Cl 、负极为铟）来量化这种可变性的程度。每个小组都被要求使用自己的电池组装方案，但遵循特定的电化学方案。结果显示组装和电化学性能存在很大差异，包括加工压力、压制持续时间和 In-Li 比率的差异。尽管如此，相对于 Li ⁺ /Li 的 2.5 和 2.7 V 初始开路电压是使用这些电活性材料的电池成功循环的良好预测指标。我们建议使用一组用于报告全固态电池循环结果的参数，并提倡一式三份地报告数据。
