This new battery concept could give electric cars a 1000km range
As you possibly know one of the biggest issues for the companies with producing electric cars is how to make batteries lighter, with more capacity, shorter charge periods and where to place them in the car as they are quite heavy. Engineers new system stacks battery cells directly one above the other across a large area, as opposed to the traditional approach where individual cells are strung side-by-side in small sections.
“Every vehicle has hundreds to thousands of separate battery cells, each surrounded by a housing and connected to the car systems and sensors. This complex design takes up space – more than 50 percent of the area dedicated to batteries inside the car is taken up with housing and contacts.
But now a team of engineers at the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has developed a new battery concept that could substantially decrease the amount of space needed for housing and contacts – meaning more batteries can fit in the same car.
The key to being able to do this is a new electrode – in this case, a metallic tape coated on both sides with ceramic storage materials. One side is the battery’s anode – the other is the cathode.”
