Electric cars are gaining traction due to their role at the heart of the energy transition. To ensure that electric cars fulfil this vital role of decarbonisation, it must be ensured that uptake continues to increase. Because of this, researchers are working to overcome one of the biggest barriers to electric car uptake \u2013 slow battery recharging rates.\u00a0<\/span>\u00a0<\/span><\/p>\n Now, researchers from Penn State have had a breakthrough in electric car battery design that has enabled a ten-minute charge time for a typical electric car battery. The team noted a record-breaking combination of a shorter charge time and more energy acquired for a longer travel range.\u00a0<\/span>\u00a0<\/span><\/p>\n The article titled, \u2018Fast charging of energy-dense lithium-ion batteries,\u2019 was published yesterday in <\/span>Nature.\u00a0<\/span><\/i>\u00a0<\/span>\u00a0<\/span><\/p>\n In August this year, California\u2019s Air Resources Board passed a significant plan to restrict and eventually ban the sale of gasoline-powered cars within the state. Further to this, the US\u2019 largest auto market aims to retire the internal combustion engine by 2035.\u00a0<\/span>\u00a0<\/span><\/p>\n To ensure that car sales will shift toward battery-powered electric cars, two of their major drawbacks need to be overcome. First, they are too slow to recharge, and second, they are too large to be efficient and affordable. Currently, some electric car batteries take all day to recharge, a huge contrast compared to taking a few minutes at the petrol station.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n Chao-Yang Wang, the William E Diefenderfer Professor of Mechanical Engineering at Penn State and lead author of the study, explained: \u201cThe need for smaller, faster-charging batteries is greater than ever. <\/span>\u00a0<\/span><\/p>\n \u201cThere are simply not enough batteries and critical raw materials, especially those produced domestically, to meet anticipated demand.<\/span>\u00a0<\/span><\/p>\n \u201cOur fast-charging technology works for most energy-dense batteries, and will open a new possibility to downsize electric car batteries from 150 to 50 kWh without causing drivers to feel range anxiety.<\/span>\u00a0<\/span><\/p>\n \u201cThe smaller, faster-charging batteries will dramatically cut down battery cost and usage of critical raw materials such as cobalt, graphite, and <\/span>lithium<\/span><\/a>, enabling mass adoption of affordable electric cars.\u201d<\/span>\u00a0<\/span><\/p>\nWhy are faster-charging electric car batteries important? <\/span>\u00a0<\/span><\/h3>\n
