Samsung SDI showcases a car battery that can be charged up to 80 percent in just 20 minutes

Tesla and GM are already doing this. 20 minutes? Too long, Supercapacitors will recharge in just 2 or 3 minutes.

Samsung SDI has showcased a next-generation car battery that offers electric vehicles a driving range of up to 600km. The high-end battery cell, which can be rapidly charged up to 80 percent in just 20 minutes, is being displayed at the North American International Auto Show (NAIAS) 2017 in Detroit. These new batteries are planned to be mass produced sometime in 2021.

Apart from this high-density battery technology for electric vehicles, the company also showcased an integrated battery module with a 10 percent decrease in component units and weight compared to current-generation models. Samsung SDI claimed in a press release that its “technological know-how in materials and processes that vastly decreased the resistance inside a battery cell" led to the development of these new batteries.
