A team of Iranian researchers has introduced a groundbreaking method for creating batteries using non-recyclable plastic waste. This innovative process not only addresses environmental waste issues but also opens new possibilities for sustainable energy storage.
Through a two-step carbonisation and activation process, the researchers successfully encapsulated selenium within fine-grained carbon derived from non-recyclable plastic. This material was then used to create lithium-selenium batteries, providing a sustainable solution for energy storage, as reported by
Pars Today, a partner of TV BRICS.
Selenium, a high-capacity element, has shown exceptional promise as a cathode material for lithium batteries, while carbon sourced from plastic waste effectively acts as a selenium receptor. The selenium integrates with the carbon through melting, resulting in a composite cathode structure that maximises energy efficiency.
Tests on plastic waste cells activated at 600°C demonstrated discharge capacity, rapid charging capabilities, and enhanced long-term stability, all of which are essential for selenium encapsulation, lithium-ion diffusion, and charge transfer.
By reusing plastic waste in this way, Iranian researchers have achieved a sustainable breakthrough with far-reaching potential in battery technology and waste recycling.
