A stable anode material for lithium-ion batteries, comprised of bio-based polymers,\u00a0could harness super-fast battery charging for electric\u00a0vehicles.<\/span>\u00a0<\/span><\/h2>\n
With pressure to move towards net-zero transport, an increasing\u00a0number\u00a0of researchers are focusing their efforts on electric vehicles (EVs) and ways to make them a more efficient alternative to conventional has vehicles.<\/span>\u00a0<\/span><\/p>\n
One key area of improvement is the lithium-ion batteries used in\u00a0EVs, with areas such as safety, durability and faster charging being important developments. Currently, it takes the most advanced EVs around 40 minutes to charge, while gas cars can be refuelled in under five minutes.\u00a0In order to\u00a0be a viable option to consumers, it is essential that charging time is reduced to under 15 minutes.<\/span>\u00a0<\/span><\/p>\n
One way to decrease the charging time of lithium-ion batteries is to increase the diffusion rate of lithium ions, which can be achieved by increasing the interlayer distance in the carbon-based materials used in the battery\u2019s anode.<\/span>\u00a0<\/span><\/p>\n
While this has been\u00a0accomplished\u00a0with\u00a0limited\u00a0success by introducing nitrogen impurities,\u00a0there is\u00a0currently\u00a0no\u00a0technique\u00a0easily available to control\u00a0the\u00a0interlayer distance,\u00a0or to concentrate the doping element.\u00a0<\/span>\u00a0<\/span><\/p>\n
