The head of the Swabian battery manufacturer, Herbert Schein, sees great demand for the new battery cell 21700, for which Varta is currently building a pilot line at the Ellwangen site: “I assume that we will be able to present the first customers this year,” said Schein the WirtschaftsWoche. For the use of the new battery cell, Varta is in talks with several car manufacturers, whereby “the local car manufacturers (…) have the highest priority”: “Our power cell is of course ideal for sports cars, for the premium segment: The battery gives a lot of power in a very short time off, for example for acceleration. “
The Varta cell 21700 can be fully charged within six minutes, explains Schein: “No other battery in this category on the market offers this property.” Schein sees several possible uses in the: “Our new cell can be used as a high-voltage battery for the drive of electric cars are used. Ideally with an optimized range extender or with an optimized fuel cell. ”The battery can also be used as a short-term accelerator for e-cars.
The new cell measures 2.1 centimeters in diameter and 7 centimeters in height, which, according to the Varta boss, offers “advantages in the efficient use of space in the car”: “When you need smaller batteries that can be quickly recharged while driving the car will be lighter and therefore need less energy, ”he told WirtschaftsWoche.
So far, the listed Varta Group has mainly produced small, rechargeable lithium-ion cells for wireless headphones, for example from, as well as household batteries for remote controls, watches and flashlights. Consolidated sales rose by around 140 percent to 870 million euros in 2020, also due to the acquisition of the household battery segment. “In the medium term,” said Schein, a third business segment could be added with the new 21700 cell. In 2024, Varta plans to be able to manufacture between 100 and 200 million 21700 battery cells per year.
