Researchers created a more efficient lithium–CO₂ battery using a simple, affordable catalyst that may help cut emissions and store clean energy.
Scientists at the University of Surrey have made a significant advance in eco-friendly battery technology, developing a system that not only stores more energy but may also help reduce greenhouse gas emissions. These lithium-CO₂ “breathing” batteries generate power while capturing carbon dioxide, offering a more sustainable option that could eventually outperform conventional lithium-ion batteries.
Previously, lithium-CO₂ batteries struggled with efficiency issues. They wore out quickly, were difficult to recharge, and depended on expensive, rare materials like platinum. Researchers at Surrey have addressed these problems by introducing a low-cost catalyst called caesium phosphomolybdate (CPM).
Through a combination of computer modelling and laboratory tests, they found that this simple change allowed the batteries to store much more energy, require significantly less power to charge, and operate reliably for more than 100 cycles.
