A new battery design that could significantly extend the range of electric vehicles and the lifespan of portable electronics has been developed by researchers at the University of Surrey\u2019s Advanced Technology Institute (ATI).<\/p>\n\n\n\n

In a study published in ACS Applied Energy Materials<\/em>, researchers introduce a novel lithium-ion battery anode that delivers some of the highest energy storage capacities reported for silicon\u2013carbon nanotube systems, while maintaining stability over hundreds of charge cycles. <\/p>\n\n\n\n

Lithium-ion batteries power much of modern technology \u2013 from smartphones and wearables to electric vehicles. Graphite, the most commonly used anode material, is stable but limited in the amount of energy it can store. Silicon, on the other hand, offers far greater capacity, but it expands during charging, causing it to crack and degrade over time. <\/p>\n\n\n\n

To overcome this, the research team developed a new \u201cVertically Integrated Silicon\u2013Carbon Nanotube\u201d (VISiCNT) structure. The design grows dense forests of carbon nanotubes directly onto copper foil and coats them with a thin layer of silicon, creating a flexible, conductive scaffold that can absorb expansion while maintaining performance. <\/p>\n\n\n\n

The resulting anode can store a very large amount of energy for its weight. In laboratory tests, it stored more than 3500 milliampere-hours per gram \u2013 close to the maximum possible for silicon and far higher than the graphite (370 mAh\/g) used in today\u2019s batteries. It also demonstrated improved stability and performance over repeated charge cycles.<\/p>\n\n\n\n

<\/p>\n\n\n\n

A key advantage of the new approach is that the carbon nanotubes are grown directly onto copper \u2013 the material already used in commercial batteries \u2013 using a scalable manufacturing process. This could make it easier to integrate the technology into existing industrial production lines.<\/p>\n\n\n\n

<\/p>\n\n\n\n

As demand for energy storage grows, batteries will need to store more energy, charge faster and last longer to support the UK\u2019s transition to Net Zero. The VISiCNT design offers a promising route to meeting these challenges and could be key to powering next-generation electric vehicles and phones.\u00a0\u00a0<\/p>\n\n\n\n
