A new battery technique may allow to solve the problem of autonomy for future electric vehicles.
Full electric vehicles have started to come into our lives, because they offer many advantages, but they still face some “childhood illnesses”: cost and limited autonomy are brake to further spread Their.
Battery prices is expected to decrease in the coming years due to their bulk production. Industry experts talk about equalizing the selling price of cars regardless of engine, at the latest from 2023.
The latest generation of electric vehicles do not have only one battery, but arrays consisting of hundreds or thousands of individual cells connected to each other. Each one needs casing, wiring and control system, components that total occupy more than 50% of the volume of the entire array. In addition, all connections that are penetrated by current have losses due to electrical resistance.
The Fraunhofer Ceramic Technology Institute hopes to have found a revolutionary solution! In collaboration with the companies ThyssenKrupp System Engineering and IAV Automotive Engineering develops the EMBATT, a new type of battery with noticeably smaller number of parts, simplified design and significantly reduced losses.

The idea is based on the integration of hives with the help of a bipolar plaque in the form of a metal film, which is coated on both sides with ceramic, polymer and electrically conductive materials. One side of the film acts as a rise and the other as descent, which, according to the Fraunhofer Institute, offers easy construction and long life.
This new battery technique benefit, however, is that cars will be able to carry larger batteries, which do not occupy more space and do not add weight, offering autonomy of up to 1,000 km.
