Samsung SDI Unveils 600km-traveling Battery Cell for EVs

Samsung SDI High-Energy Density EV Battery delivers 600km range and 80% fast charging in 20 minutes, plus an integrated battery module for higher kWh, improved safety, lighter design, and manufacturing efficiency for electric vehicles.

Samsung SDI is still trying to win trust from global customers. At this year’s North American International Auto Show (NAIAS) held in Detroit, Samsung SDI presented a high energy density battery cell and a concept battery module for electric vehicles (EVs), aligning with broader industry roadmaps such as Daimler's electrification plan underway.

The high energy density battery cell allows EVs using it to travel up to 600km, while the fast charging technology, exemplified by ABB's Terra 360 ultra-fast charger, allows 80% of the capacity to be charged in simply 20 minutes for traveling 500km. This means that only 20min in the highway rest area will be enough for a battery to be charged, eliminating the range anxiety of EV drivers.

Samsung SDI scheduled to start mass production of this new battery cell in 2021, echoing predictions like Musk's three-year timeline for cheaper, more powerful EV batteries.

In addition to the battery cell, Samsung SDI released a concept “integrated battery module” at the tradeshow as well. A conventional EV battery module which consists of 12 cells has a capacity of 2~3kWh, while the “integrated battery module” has more than 24 cells with a higher capacity of 6~8kWh, which makes it an adequate module in the full-fledged high-capacity EV era.

The integrated battery module shows a higher safety level because the advanced electro-mechanical design has been applied. This concept is expected to be a boon in the electro mobility, as it will be lighter with fewer components and supports trends in grid flexibility driven by rising EV adoption.

“The high-energy density battery cell with the fast charging capability and the integrated battery module are the innovative technologies with full potentials that can transform the market,” said an official from Samsung SDI. “Expectations are high that we will be able to accelerate the vehicle electrification across an industry where GM and Ford battery strategies are diverging to meet demand, utilizing these technologies with improved driving range, manufacturing efficiency and user convenience.”
