Supercapacitor Activated Carbon for Organic Electrolyte and Aqueous Electrolyte Energy Storage Systems

Product Overview

This high-purity activated carbon is specifically engineered as a premium electrode active material for high-performance supercapacitors, hybrid capacitors, and energy storage devices. Designed to deliver superior charge-discharge kinetics, this advanced material features an ultra-high specific surface area, exceptionally low ash content, and optimized pore architecture tailored for both organic electrolyte and aqueous electrolyte systems. By facilitating rapid ion diffusion and maximizing electrochemically accessible surface area, this powder provides an outstanding balance of energy and power density.

Primarily utilized in the manufacturing of electric double-layer capacitors (EDLCs), hybrid supercapacitors, lead-carbon batteries, and next-generation fuel cells, this material ensures minimal equivalent series resistance (ESR) and exceptional cycle longevity. Its stable chemical profile effectively suppresses parasitic side reactions such as hydrogen evolution, making it the material of choice for industrial battery and capacitor manufacturers, high-rate electrochemical R&D laboratories, and advanced energy research institutions.

Engineered under stringent quality controls, this electrode carbon exhibits consistent bulk density, tightly controlled particle size distribution (D50), and trace-level metal impurities. Whether integrated into coin cells, cylindrical wound cells, or large-format prismatic supercapacitor packs, this material consistently delivers high specific capacitance, superior mechanical integrity during slurry processing, and robust stability under demanding high-voltage and high-current operational profiles.

Key Features

• Ultra-High Specific Surface Area: Optimized multi-modal pore network provides BET surface areas up to 2500 m²/g, maximizing active charge accumulation sites while preserving rapid electrolyte ion accessibility in both non-aqueous and aqueous media.
• Low Internal Resistance and High Conductivity: Delivers electrical conductivity up to 0.40 S/mm with low bulk resistivity, significantly reducing cell internal resistance and heat generation during high-rate galvanostatic cycling.
• Minimized Hydrogen Evolution: Tailored surface chemistry and high chemical purity inhibit parasitic hydrogen evolution reactions, dramatically enhancing the working potential window, charge retention, and operational safety in high-voltage configurations.
• Ultra-Low Ash and Metallic Impurities: Controlled to less than 0.5% ash and under 50 ppm iron content, preventing self-discharge, micro-shorting, and localized electrolyte catalytic decomposition over extended operational lifecycles.
• Tailored Electrolyte Compatibility: Available in specialized formulations optimized for solvent wetting and ion transport in organic solvents (acetonitrile, propylene carbonate) and aqueous electrolyte solutions (potassium hydroxide, sulfuric acid).
• Uniform Particle Size Distribution: Narrow micron-scale particle sizing (D50 ranging from 5.0 to 10.0 µm) promotes dense, crack-free electrode coatings with exceptional adhesion and homogeneous packing on current collectors.
• Superior Cycle Life and Capacitance Retention: Retains high reversible capacitance (up to 260–300 F/g in aqueous systems and 140–160 F/g in organic systems) across tens of thousands of continuous charge-discharge cycles.

Operational and Safety Handling Guidelines

• Storage Requirements: Store in a cool, strictly dry, and well-ventilated warehouse away from direct ignition sources, combustible materials, and strong oxidizing agents.
• Package Integrity: Maintain hermetically sealed packaging until ready for slurry preparation. In the event of packaging damage, reseal immediately; high-surface activated carbon actively adsorbs ambient air, moisture, and VOCs, which can induce exothermic self-heating.
• Enclosed Space Caution: Do not expose bulk active powder in unventilated or confined spaces, as continuous adsorption of ambient atmospheric gases can locally deplete oxygen and create hazardous breathing environments.

Why Choose This Product

• Precision Pore Engineering: Synthesized through controlled activation methods to produce tailored micropore and mesopore ratios that match the solvated ion radii of both organic solvents and aqueous electrolytes, preventing pore clogging and maximizing capacitance.
• Batch-to-Batch Consistency: Strict automated thermal processing and purification protocols ensure tight tolerances on BET surface area, particle size, and conductivity, eliminating slurry rheology variations and coating defects during pilot and mass production.
• Low Impurity Profile for High Voltage Reliability: Low ash (<0.5%) and ultra-low transition metal content (<50 ppm Fe) suppress internal parasitic side reactions, preventing gas generation and premature device degradation during high-voltage float testing.
• Comprehensive Process Integration Support: Backed by extensive expertise across the entire cell manufacturing workflow, including slurry mixing parameters, doctor-blade coating recommendations, calendering density targets, and electrolyte wetting optimization.
