Manchester Scientists Revolutionize Battery Tech with One-Atom-Thick Filter
Scientists at the University of Manchester are making strides in battery technology. Led by Professor Saverio E. Spagnolie and Dr. Richard Beanland, they've developed a one-atom-thin filter for lithium-sulfur batteries, which could revolutionise energy storage.
Lithium-sulfur batteries offer advantages over lithium-ion batteries. They're lighter and have higher energy density, making them ideal for various applications. From consumer devices to freight trucks, trains, and ships, these batteries could overcome the challenge of battery weight.
The secret lies in the one-atom-thick filter. It blocks sulfur chains from moving within the battery, preventing power loss and extending lifespan. Unlike unfiltered batteries that quickly lose performance, these retained nearly all their capacity over more than 150 charge-discharge cycles. The filter was created using chemical vapor deposition on a copper foil, resulting in a graphene film with precise openings.
The one-atom-thick filter is a significant breakthrough for lithium-sulfur batteries. It addresses the weight compounding issue, especially crucial for larger vehicles. With an average electric vehicle battery weighing about 1,000 pounds and offering 200 to 250 miles of range, this innovation could extend that range, paving the way for more efficient and sustainable energy storage solutions.
