Safety-related design of pouch cells with future ones High-performance materials standardization of format and Test method (BaSS)


Germany and China share the goal of supporting the expansion of electric mobility as a resource‐
conserving technology. Bilateral academic research collaborations between the two countries are
expected to make significant progress in innovative charging technologies and the efficiency of
electronic components and systems. Among other things, the results will be used to further intensify
German‐Chinese standardization cooperation in the field of electromobility.

Goals and approach

To increase vehicle range, improved battery systems with higher energy storage density are required.
Pouch cells, which can be packed comparatively densely, are in principle well suited for the
construction of such systems, but there are currently many different cell formats. The BaSS project
aims to advance the development and standardisation of lithium‐ion pouch cells. The core objective
of the project is to develop new cell components and joining concepts and to harmonize cell formats
while taking into account the requirements of the German and Chinese markets. Close cooperation
with the partner university in China will ensure that the standardisation approaches pursued in both
countries are effective.

Innovations and prospects

The combination of standards enables a more efficient design of cell production and a higher
comparability of performance. This can accelerate the development of new battery generations and
pave the way for more efficient and cost‐effective electric vehicles.
