Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes.

Development of supercapacitors is a core group of scientists from the University of California, riverside. Previously they were able to create a generic experimental design of such energy storage and now they are engaged in the search for the best materials for its components. Behind and validation of graphene and recycling of glass bottles, and now they’re engaged in PET packaging.

In simplified form, processing of plastic looks like. The pieces of the bottle were dissolved and subjected to electrospinning to separate the individual fibres. Those are burned in a furnace for carbon emissions, which is mixed from two components – binder and conductive. The resulting material becomes part of the bilayer plates nanometer size, which is used as electrode of supercapacitor.

The main advantage of the supercapacitor before the same lithium-ion batteries high speed charging, but for that you have to pay a significantly lower battery capacity. Therefore, for effective operation of the equipment requires a lot of supercapacitors, and therefore the components should be cheap and easy to manufacture. Use for these purposes PET will allow to solve two tasks: to save on production and reduce waste. This is what’s called “upcycling” or recycling is a simple plastic recycling.

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]

Under this small iron hatch is the deepest hole of our planet

In the spring of 2020, the authorities of the Murmansk region, where geographically the Kola superdeep borehole, has announced plans to turn this monument of science into a full-fledged tourist site. Easy to say, but difficult to do – the building has been destroyed and looted, and the mine is like an iron disk, bolted […]
