Story summary

Researchers have developed a method to convert discarded PET plastic bottles into supercapacitors.
The process heats the plastic to create a porous carbon powder that forms the electrodes, addressing plastic waste from over 500 billion single-use PET bottles produced annually.
Tests show the devices outperform models, while being cheaper and fully recyclable.
Commercial availability is expected within 5 to 10 years, potentially lowering costs for electric vehicles and solar systems.
