Cambridge Researchers Develop Atom-Thick Filter for Longer EV Range
Researchers at the University of Cambridge have developed a groundbreaking atom-thick filter for lithium-sulfur batteries. This innovation could significantly extend the range of electric vehicles and the lifespan of phone batteries.
The filter, created using chemical vapor deposition, is a graphene film with precise openings. It blocks sulfur chains, preventing them from shuttling within the battery and causing power drainage. This breakthrough allows lithium-sulfur batteries to maintain their charge, demonstrating nearly full capacity over more than 150 charge-discharge cycles.
Lithium-sulfur batteries, already lighter and more powerful than conventional lithium-ion batteries, could now see wider adoption. The potential applications extend to freight trucks, trains, and ships, where battery weight is a major obstacle. However, much work remains before these batteries with atom-thick filters can be manufactured at scale and used in everyday devices.
The new atom-thick filter concept for lithium-sulfur batteries, developed by Cambridge researchers, holds great promise for extending the range and lifespan of electric devices. While more development is needed for large-scale manufacturing, this innovation brings us a step closer to more efficient and sustainable energy storage solutions.
