Rapid charging is the key for a wide spread of electric cars. US Department of Energy wants to achieve for EV batteries a standard "extreme fast charging (XFC)", which will enable a fully charge to a 200-mile range in less than 10 minutes. A critical barrier to XFC is Litium plating, which occurs at high charge rates and drastically deteriorates battery. Increasing temperatures for short periods seems result in less Li plating, scientists at Penn State University (Pennsylvania; US) reveals
