Fraunhofer evaluates battery cell formats

The Fraunhofer battery alliance has published a study with focus on development perspectives of cell formats used in li-ion batteries for electric vehicles.

The research team examined and evaluated different formats and found out that until 2025, particularly the pouch format and the 21700 format seem to be the most promising cell types. In the long term, the team states that large-size LIB cells will dominate the EV battery cell market.

Indeed, the market for battery cells is still quite heterogenic: While Samsung bets among others on prismatic cells, LG goes rather for the pouch format and Panasonic launches its 18650 and 21700 cells in cylindric format.
