We told you this edition of the Frankfurt Motor Show was really about the popularization of electric vehicles – even Samsung SDI knows that, which is why they brought their latest innovations in terms of EV batteries to the show.
Their most important novelty has to be the new “Multifunctional battery pack” – it’s a modular system that allows clients, e.g. automakers, to “change the number of modules as they want as if they place books on a shelf.” Samsung exemplifies this idea with a hypothetical premium car featuring 20 modules – that would be good for 600 to 700 kilometers (370 to 435 miles). Lower the count to 10 to 12 modules on a regular sedan and you could get 300 kms of range. Another interesting idea, separate of the previous one, is the “Low Height Cell” – it’s 20 percent shorter than existing cells and can help carmakers amplify interior space.
And now onto the Tesla target – Samsung SDI also presented its own version of the new 21700 standard of cylindrical battery, which is 21 millimeters in diameter and 70 millimeters in height. These are the cells used by Tesla for its latest energy storage products, but also for the new Model 3, with the larger S and X expected to adopt them soon. The 21700 standard has 50 percent bigger capacity compared to the existing 18650 battery (18 millimeters in diameter and 65 millimeters in height). Samsung SDI has just commissioned a new EV battery plant in Hungary this May, and has production capacity in Ulsan, South Korea and Xian, China, as well.
