When a lot of energy is stored quickly, the battery cell is inevitably exposed to higher temperatures. Ultra-thin, ceramic-impregnated separators made of polyester nonwovens for lithium-ion batteries ensure the cell’s temperature stability up to several hundred degrees Celsius. Thanks to powerful separators, the cells are also less susceptible to increasingly energy-rich electrodes and mechanical loads, even at higher temperatures. This makes them particularly safe in the event of accidents.
Meanwhile, numerous countries have announced their exit from the traditional world of internal combustion engines. Alongside China and India, the list now includes Great Britain, France, Norway, the Netherlands and the US state of California. In Norway alone, the share of newly registered electric vehicles in 2016 was almost 30 percent.

The dream of nationwide, more environmentally friendly locomotion seems to be, albeit slowly, edging towards reality. User benefits such as tax savings, free parking or the use of bus lanes are attracting more and more people and providing an additional incentive to save CO2. Tillmetz is convinced: “Anyone who has driven a powerful car with an alternative drive will never want to change back to petrol or diesel. Not just for the clear conscience, but also because these vehicles are simply fantastic to drive.”
