The project "Betterbat - Assessment of the Technical and Systemic Fit of Battery Technologies for Battery-Relevant Applications" addresses the systematic analysis and assessment of the suitability of battery technologies for different applications from the user perspective. To this end, the Chair of Electrochemical Energy Conversion and Storage Systems Technology at RWTH Aachen University (ISEA), the Fraunhofer Institute for Solar Energy Systems (ISE), the Fraunhofer Institute for Systems and Innovation Research (ISI), the Fraunhofer Institute for Silicon Technology (ISIT) and the Institute of Automotive Technology at TUM (FTM) are working together on the project.

"BetterBat" intends to provide answers to the questions: For which applications can battery solutions be considered today or in the future? Which battery technology fits which application? How are applications and battery technologies developing and what are the requirements of the future?

Within the project, ISEA coordinates the development of a multi-criteria GAP analysis procedure that quantifies the current and future fit between relevant usage scenarios of an application and cell technologies and estimates further developments on both sides. The merging of cell technologies and applications represents the core of the project. The results of the GAP analysis will be used to derive recommendations for action for the industry in order to be able to close the existing gaps between the application aspect and the cell technology aspect. Following the development of the process, it will be integrated into a web platform. The web platform provides both the application side and the cell development side with an uncomplicated link. The application side can use the GAP analysis to identify a suitable cell technology and the cell development side can base the production of new technologies on known application requirements.

Throughout the project, ISEA focuses primarily on stationary applications and is involved in several work packages of the project. For the development of this project, experiences from research projects in the topics of home storage, commercial storage and large-scale storage as well as cell characterization are applied and extended.
