Fabrication of PS plastic film for efficient energy storage

The team of Nano Scientists and Research Scientists led by Dr. Xie Xian Ning, National University of Singapore, has developed: soft, foldable membrane using a PS plastic. This thin film is more energy-efficient than current batteries.

When clamping this PS plastic film between two charged metal plates, the membrane can be charged at 0.2 farads per square centimeter, the charge is higher than the typical upper limit of a standard capacitor (likely charge about 1 microfarad per square centimeter.

Compared to rechargeable batteries and supercapacitors, this exclusive PS plastic film has a very simple device configuration and low manufacturing cost, said Dr. Xie. "Moreover, the performance of this proprietary PS plastic film surpasses rechargeable batteries, such as lithium ion batteries and lead-acid batteries, and supercapacitors."

The cost of storing each electrical farad is $ 0.62 (about £ 0.40) compared to about $ 7 (about £ 4.5) for each electrical farad stored by electrolytes. liquid based on current technology. This means: When using this exclusive PS plastic film, at a cost of US $ 1, the amount of storage energy is between 10 and 20 watts per hour, compared to using lithium ion batteries with chi At US $ 1, the amount of storage energy is only about 2.5 watts per hour.

The results of this study came into being in the context of public concerns about the negative impacts of traditional energy sources on the environment and the general trend, now looking for alternative energy sources, aimed at develop environmentally friendly transportation vehicles such as: electric cars.

Hybrid cars (which use electric motors to support gasoline engines) can benefit from PS plastic film technology to store and convert energy almost immediately, helping to improve energy efficiency. carbon emissions and reductions.

PS plastic films can also be integrated into solar panels and wind turbines to help store and manage electric energy more efficiently, contributing to solving energy instability , a problem. threads are common in solar systems, by storing excess energy and providing electricity at times when natural elements do not provide enough energy, such as: lack of solar energy At night.

The team is currently looking for opportunities to partner with venture capitalists to commercialize this proprietary PS plastic film.
