BetterBat – Evaluation of the technical and systemic fit of battery technologies for battery-relevant applications

The “BetterBat” project addresses the interface between battery technology and its potential use in an application. “BetterBat” thus explicitly focuses on the user side and its systemic, application-specific requirements, thus enabling target-oriented research and development, shortening the time-to-market accordingly and reducing the risk of failing to meet market requirements. “BetterBat” is intended to provide answers questions such as: For which applications can battery-electric solutions be considered today or in the future? Which battery technology is suitable for which application? What are the strengths and weaknesses and where might further research or funding be required? The work packages required to answer these questions are shown schematically in the following figure.

Within the scope of the project, seven relevant fields of application for the establishment of battery solutions will be analyzed and evaluated. In a first step, promising applications are selected and detailed requirement profiles are determined. For these applications, the potential range of current and future cell and system technologies will then be determined, and the suitability of the selected cells and systems for the various applications will be quantified and the associated systemic conditions analyzed. In a downstream GAP analysis, both perspectives are combined to obtain information on the suitability of battery solutions for the applications under consideration. Both the current status quo and future developments (development potentials) are covered under the boundary condition of possible market dependencies. For cases with a high potential, concrete options for action and solution approaches are then developed to increase the fit. To ensure that further applications can be analyzed and evaluated with the help of the developed procedure even after the end of the project, the procedure for selecting and analyzing promising applications is finally standardized.
