Lithium Capacitors: Advanced Hybrid Supercapacitor Technology by VINATech USA
VINATech USA is proud to introduce our advanced family of Lithium Capacitors, also known as Hybrid Supercapacitors. These capacitors combine the best features of lithium-ion batteries and supercapacitors, offering high voltage, low self-discharge, and superior performance across a wide range of applications. Our Lithium Capacitors are designed to deliver reliable, efficient, and long-lasting energy storage solutions.
Overview of Lithium Capacitor Technology
Lithium Capacitors, or Hybrid Supercapacitors, integrate lithium-ion technology with electric double-layer capacitor (EDLC) principles. This combination results in capacitors with higher energy density, higher operating voltage, and lower self-discharge compared to traditional supercapacitors. VINATech’s Lithium Capacitors are engineered to meet the demanding requirements of modern energy storage applications.
Vina Pulse Capacitor (VPC) Series
The Vina Pulse Capacitor (VPC) series represents VINATech’s latest innovation in Hybrid Supercapacitors. These capacitors are designed to provide cost-effective, high-performance energy storage with ultra-low leakage current. Key features include:
High Capacitance
Offers greater energy storage capacity.
Low Self-Discharge
Minimizes energy loss over time, ensuring efficient energy storage.
Wide Operating Temperature Range
Reliable performance from -25°C to +85°C (extended to -40°C to +85°C in Li/SOCL2 battery systems).
High Operating Voltage
Operating voltage range of 2.5V to 3.8V (2.5V to 3.5V at 85°C).
Advantages of VPC Series
The VPC series is developed using standardized EDLC production processes, which reduce production costs while maintaining high performance. These hybrid lithium capacitors offer several advantages over traditional pulse battery technologies:
Higher Discharge Currents
Suitable for applications requiring rapid energy delivery.
Lower Equivalent Series Resistance (ESR)
Ensures efficient energy transfer and quick discharge capabilities.
Longer Life
Capable of withstanding up to 50,000 cycles, providing long-term reliability.
Wider Temperature Range
Performs reliably in extreme temperatures, enhancing versatility.
