Industrial modular battery pack concept addressing high energy density, environmental friendliness, flexibility and cost efficiency for automotive applications


Motivation and approach

The current commercial battery technology that will most probably dominate the market for another decade is based on lithium. Although having strong advantages in performance compared to other battery solutions on the market, the technology is far from preventing the range anxiety effect for vehicle users. To improve this issue, several challenges are currently addressed at cell electrochemistry and BMS level.

The approach of this research project has a more practical scope. The fundamental challenge in particular is to maximize the energy density of Li-ion (lithium-ion) packs through the optimization of the structural design and components of a battery pack (BP) for a given cell form-factor. In other words, the pursued strategy is to increase the energy density by reducing the weight of the BP while keeping the structural integrity and an easy assembly and manufacturing process.

Research objective

The overall research issue is to increase the energy density while simultaneously reducing the cost of battery packs. Further, the current production of BP has heavy impact on the environment. A new generation of BPs should be eco-designed and be based on an overall environmentally friendly concept. New methods of recycling should be developed and improved to increase the level of battery reusability.

The aim of iModBatt is therefore to design and manufacture a high energy density, modular battery pack that is flexible enough to be used in automotive and small stationary applications with a minimum of environmental impact. This battery pack will be suitable for automated assembly with an easy-to-disassemble design. Easy extension and adjustment of the BP to suit the application and to facilitate the BP recyclability or parts replacement if necessary can thus be assured.

The project consortium includes industrial partners along the battery pack value chain, including automotive OEMs, battery parts manufacturers as well as leading European research centers with experience in battery technology.
