Product description
Product Name: High-Performance Materials for Supercapacitor (Electrochemical Capacitor) Development
Product Summary
Our Supercapacitor Research Materials portfolio is focused on providing the specialized components necessary for advancing Electrochemical Capacitors (ECs), also known as supercapacitors or ultracapacitors. These devices are critical in New Energy Research due to their capacity for rapid charge/discharge cycling, high-power density, and extremely long cycle life (often exceeding 100,000 cycles), which distinguishes them from traditional batteries.
We supply a carefully selected range of nanostructured carbons, pseudo-capacitive metal oxides, and high-conductivity electrolytes that are rigorously tested to maximize surface area and minimize internal resistance, enabling breakthroughs in power delivery and energy storage.
Key Material Categories
| Category | Examples | Primary Function |
| Porous Carbons | Activated Carbon (AC), Graphene, Carbon Nanotubes (CNTs), Porous Carbon Sheets | Electrochemical Double-Layer Capacitance (EDLC). Provides high surface area for charge adsorption/desorption. |
| Pseudo-Capacitive Materials | Metal Oxides (e.g., RuO₂, MnO₂), Conducting Polymers (e.g., PANI) | Faradaic Charge Transfer (Fast, surface-limited redox reactions for increased energy density). |
| Hybrid Electrodes | Carbon/Metal Oxide Composites, Layered Double Hydroxides (LDHs) |
Primary Applications
High-Power Energy Storage:
Pulsed Power Devices: Used where rapid energy delivery (e.g., seconds) is required, such as in electric vehicle acceleration, industrial lasers, and flash photography.
Cycle Life Enhancement:
Hybrid Systems: Integrated with batteries in electric grids or vehicles to handle high-power peaks, thereby extending the battery’s lifespan.
Electrode Fabrication:
Synthesis and Testing: Used to formulate electrodes with customized architectures (e.g., hierarchical porous structures) to optimize ion access and minimize diffusion resistance.
Novel Electrolyte Development:
Research into non-aqueous and ionic liquid electrolytes to safely expand the cell’s operating voltage window beyond the limits of aqueous systems, which directly increases the energy density ().
Technical Significance
The materials used in supercapacitors are highly structure-dependent:
Porous Carbons: The pore size distribution must be precisely controlled to match the size of the electrolyte ions for maximum capacitance.
Pseudo-Capacitive Oxides: These materials offer much higher energy density than carbons but are often limited by low conductivity and cycle stability, necessitating the use of nanostructuring and carbon composites.
Ordering and Consultation
We offer highly characterized carbon materials (e.g., specific surface area, pore volume) and high-purity metal precursors.
Expert Support: Our technical team can advise on the selection of optimal electrolyte systems (e.g., aqueous for low cost/high power vs. organic for high voltage/high energy) to match your supercapacitor design goal.
Flexible Supply: Available in research-grade quantities for lab-scale prototyping and larger volumes for pilot manufacturing.
