High Purity Supercapacitor Electrolyte Solution for Advanced Energy Storage

Product Overview

This high-purity supercapacitor electrolyte is an acetonitrile-based organic solution formulated specifically for electric double-layer capacitors (EDLCs) and advanced pseudocapacitive energy storage systems. Featuring an optimized 1 mol/L salt concentration dissolved in high-grade acetonitrile (AN), this chemical solution delivers rapid ion transport kinetics, minimal equivalent series resistance (ESR), and an expanded operational potential window reaching up to 3.0V.

Designed to satisfy the stringent requirements of high-rate discharge and rapid-cycling applications, this solution serves as a critical component in grid energy stabilization, automotive regenerative braking, heavy industrial pulse power, and precision laboratory prototyping. Its exceptionally low moisture content and strictly controlled trace metal impurities prevent side reactions, minimize gas generation, and ensure electrochemical stability during continuous float charging and dynamic power delivery.

Manufactured under rigorous inert-atmosphere conditions, the formulation guarantees consistent batch-to-batch chemical purity and ultra-low internal resistance. It empowers researchers and cell manufacturers to achieve maximum power density, extended cycle life beyond hundreds of thousands of duty cycles, and dependable performance under severe cold and high-rate current demands.

Key Features

• High Operating Voltage Window (Up to 3.0V): Advanced solvent purification and electrochemical stabilization enable stable operation from 2.7V to 3.0V, significantly increasing total stored energy density ($E = \frac{1}{2}CV^2$) without inducing electrolyte decomposition.
• Ultra-High Ionic Conductivity (56 ± 2 mS/cm at 25°C): The acetonitrile-based solvent matrix provides exceptionally high dielectric properties and low viscosity, enabling ultra-fast ion transport between activated carbon micropores.
• Strict Moisture Control (≤ 20 ppm): Formulated and packaged in an ultra-dry environment, trace water content is suppressed below 20 ppm to eliminate parasitic hydrolysis, internal gas evolution, and premature pouch or can swelling.
• Minimized Trace Impurities: Stringent purification protocols restrict multivalent metal ions (Fe, Ca, Pb < 1 ppm; Na < 10 ppm) and harmful anions ($Cl^- < 1\text{ ppm}$, $SO_4^{2-} < 5\text{ ppm}$), preventing electrode passivation and current leakage.
• Low Internal Resistance (ESR) Optimization: The chemical formulation directly reduces bulk and interfacial impedance, maximizing power output during high-frequency pulse discharges and fast-charging cycles.
• Robust High-Current Discharge Performance: Designed for heavy-duty pulse loads, the liquid electrolyte sustains high current rates with minimal Joule heating and negligible polarizability losses.
• Outstanding Low-Temperature Operation: Exceptional thermodynamic stability and low solvent freezing threshold allow device functionality in sub-zero environments without phase separation or catastrophic conductivity drops.
• Controlled Acidity Profile (< 20 ppm): Neutralized acid levels protect aluminum current collectors and active electrode binders from chemical corrosion, ensuring reliable long-term shelf life.
