Recent Research and Progress in Batteries for Electric Vehicles

Fichtner, Maximilian

Abstract:
The actual batteries in use: The current progress in the performance and sustainability of traction batteries is due to a combination of engineering and chemistry progress. More space for material in the battery pack allows more creativity in the choice of materials leading to batteries with longer range, faster charging, and more sustainable composition.

The developments in the field of e-mobility currently exceed all previous goals and expectations, and the speed of development is rapid. The battery costs dropped by 98 % in the last three decades and the storage capacity increased by a factor of three to four in the same period. The recent strong progress in the development of lithium-ion batteries (LIB) can be associated to both the progress in the engineering of the battery pack, and the progress of active materials for the cathode. From the system perspective, only a fraction of the overall improvement is due to better chemistries. Even larger contributions are expected from new cell-to-pack and the cell-to-chassis designs. The new designs provide more space for the active material so that also less energetic, but more sustainable, safer and cheaper materials can be (re)considered, such as LiFePO4 which encounters a renaissance at the moment. ... mehr
