Heshan City, Guangdong, China – The Institute of Electrical Engineering of the Chinese Academy of Sciences has announced a significant breakthrough in the performance of energy storage capacitor films by utilizing GMY ultraviolet lamps in their manufacturing process.
In this breakthrough study, the excimer UV lamps developed by GMY Lighting Technology [https://www.gmylight.com/], nearly doubled the energy discharge density of capacitor films and increased the high-temperature “short-burst” performance by up to 52%.
UV Breakthrough Enhances Capacitor Film Performance
Biaxially Oriented Polypropylene (BOPP) film capacitors are widely used for energy storage: in communication equipment, medical devices, and consumer electronics to ensure efficient energy transfer and storage. They are essential in electric vehicles (EVs) and other critical applications that require short bursts of increased power.
Currently, these BOPP films experience a bottleneck at high temperatures; a critical constraint EV, and other high temperatures. By utilizing GMY UV lamps in their manufacture, this problem is reduced significantly.
The breakthrough study utilized commercially available 172nm and 222nm ultraviolet excimer lamps developed by GMY. These environmentally friendly lamps provide UV light with high photon energy.
These UV lamps directly irradiated and modified BOPP in ambient air, forming better, thermally stable bonds without introducing any manufacturing issues.
The UV-modified BOPP film’s breakdown field increased by 52% at 120°C (248°F). At room temperature, the energy discharge density improved from 4 MJ/m³ to 7.5 MJ/m³, with a 17% improvement in the breakdown field.
GMY Products Made the Difference
GMY’s UV products played a pivotal role in this performance breakthrough.
A key element is this: applying UV to BOPP manufacture is a “soft” modification. The process doesn’t require any chemical reagents or produce high-pollution by-products. The simple addition of UV provides results with a single-step process, high throughput, and low energy consumption, and significantly improves the performance of energy storage capacitor films.
This method can be extended to other high-temperature dielectric films, demonstrating versatility.
