Vina Pulse Capacitor (VPC) is a Hybrid Supercapacitor (also known as Hybrid Capacitor) developed by a Korean supercapacitor manufacturer VINATech.
It combines the best characteristics of batteries and supercapacitors. In this video, we are going to show you the results of 5 safety tests that were conducted in order to demonstrate the exceptional safety characteristics of VPC under the most extreme conditions.

The purpose of those tests is to prove that VPC can is more stable and safer in comparison to batteries.
The ability to undergo extreme conditions without combustion or explosion is important for those applications which require safety and reliability.
1. VPC: Technical Specifications
Product Name Rated Voltage Operating voltage Capacitance Operating temperature Weight(g)

2. Test Descriptions and Comments

1) VPC Short-Circuiting
The VPC cell is short-circuited by connecting its two wires together. The Temperature goes up to 114℃ without any combustion or explosion occurring.

2) VPC Penetration
The VPC cell is penetrated with the nail which causes internal short-circuiting. The Temperature goes up to 103℃ without any combustion or explosion occurring. A small amount of electrolyte is released as the casing is breached.

3) VPC Crushing
The VPC cell is crushed with pliers. The Temperature goes up to 114℃ without any combustion or explosion occurring.

4) VPC Burning
The VPC cell is burned with the flame directed at it. The cell doesn’t explode. The safety vent opens, and the electrolyte vapor is released with the pressure. VPC cells don’t pose the danger when exposed to open fire even for extended periods of time. The electrolyte does not combust.

5) VPC Overcharging
VPC cell is charged with 2 amperes at 5.0V. The overcharging causes the temperature and pressure to increase within the cell. When the cell’s temperature exceeds 140 ℃, the safety vent opens and releases the electrolyte vapor without any combustion or explosion occurring.

Vina Pulse Capacitor shows outstanding characteristics of safety and doesn’t explode or combust when being short-circuited, penetrated, crushed, burnt, and overcharged. Therefore, Vina Pulse Capacitor can be widely used as a backup power source or even as the main source in a variety of applications that require safety and stability.
