This product is designed for use in coin-cell assembly and research evaluation of high‑nickel cathode materials, including NCM811, 622, 523, 111, and NCA. Formulated as a universal ternary electrolyte, it features a measured conductivity of 8.12 mS/cm, low free acid content (under 50 ppm as HF), and a water content below 20 ppm, ensuring stable electrochemical performance and minimal side reactions. The electrolyte is supplied in aluminum‑bottle packaging with aluminum‑plastic film and requires storage in a glovebox under controlled moisture (<5 ppm) and temperature (<24 °C) conditions to maintain a six‑month shelf life. With a density of approximately 1.2126 g/cm³ and a Hazen color below 50, this electrolyte supports consistent wetting and reliable data in comparative cathode studies. Available in multiple gram‑scale sizes, it suits laboratory‑scale research and screening of advanced lithium‑ion battery materials.
