Product Overview & Key Features
The LIHC0813-3R8-20F is a high-performance 3.8V 20F Lithium-Ion Hybrid Capacitor (LIHC) that bridges the gap between traditional supercapacitors and lithium batteries. Utilizing a unique hybrid structure, it delivers an exceptional combination of high energy density, rapid power discharge, and an ultra-long lifespan, making it the ideal energy-buffering and backup-power solution for IoT devices, smart meters, and industrial electronics.
High Energy & Power Density: Seamlessly handles peak-current loads with rapid power discharge and extended storage.
Ultra-Long Cycle Life: Engineered to endure over 250,000 cycles, minimizing long-term maintenance and replacement costs.
Low Self-Discharge: Exceptional charge retention, perfect for intermittent power harvesting or long-term standby.
Wide Temperature Range: Operates reliably in harsh environments from -40°C to 70°C.
Safe & Certified: Fully compliant with UN38.3 and MSDS standards for secure international transit and operation.
Product structure
Cathode: Activated carbon (capacitive electrode)
Anode: Lithium-ion intercalation material (e.g., graphite)
Separator: Ion-permeable insulating membrane
Electrolyte: Organic electrolyte system
Component Descriptions:
Aluminum Shell: Provides robust mechanical protection and reliable sealing performance.
Electrode: The core material for energy storage, enabling high-performance lithium-ion energy storage through hybrid electrochemical mechanisms.
Diaphragm (Separator): Effectively isolates the positive and negative poles to prevent short circuits caused by direct contact, while allowing the seamless passage of electrolyte ions.
Lead (CP Wire): Tinned copper-clad steel wire featuring high conductivity, excellent bending performance, and superior solderability, serving as the primary bridge for external energy transmission.
Rubber Plug: Formulated from high-grade elastomer material to provide a secure seal and insulation, preventing terminal short-circuits, electrolyte leakage, and evaporation.
Physical Dimensions and Packaging
The LIHC0813-3R8-20F features a cylindrical aluminum shell that provides robust mechanical protection and excellent sealing performance. The premium rubber plug effectively insulates the terminals from the housing, preventing short circuits, electrolyte leakage, and evaporation.
