Samsung has unveiled a battery that can give electric cars a driving range of up to 500 kilometers (310.7 miles) on a 20 minute charge, promoting technology that could be key to the future of autonomous driving.

The South Korean conglomerate's battery division known as Samsung SDI, announced the cell on Monday, and said it can offer a complete driving range of up to 600 kilometers. A 20-minute charge will give the battery 80 percent capacity, allowing for a 500 km range.

"This means that only 20 minutes in the highway rest area will be enough for a battery to be charged, eliminating the range anxiety of electric vehicle drivers," Samsung SDI said in a press release, adding that mass production of the cell is slated for 2021.
