Integration of smart functionalities
Increasing safety, reliability and cycle life of batteries by introducing smart sensing and self-healing functionalities.
Even the best battery will eventually fail. Degenerative processes within a battery cannot be suppressed completely, and external factors such as extreme temperatures, mechanical stress, excessive power during operation, or simply ageing will, given time act detrimentally on battery performance. From the perspectives of sustainability, economic efficiency, and reliability, new ways need to be found to increase safety and lifetime particularly in critical applications.
The BATTERY 2030+ vision is to incorporate smart sensing and self-healing functionalities into battery cells with the goals of increasing battery durability, enhancing lifetime, lowering the cost per kWh stored, and, finally, significantly reducing the environmental footprint.
Non-invasive sensing technologies offering both spatial and time resolution will be developed to monitor key battery cell parameters during operation and to determine defective areas or components within the cells that need to be repaired by activating/adding self-healing functions. In the battery of the future, sensors will make it possible to follow chemical and electrochemical reactions “in vivo” directly inside a battery cell during real-world operation. New sensor technologies will emerge that can diagnose the early stages of battery failure, thermal runaway, and unwanted side reactions leading to early battery ageing.
Self-healing functionalities will become an important property of future batteries in applications that require batteries with high reliability, high quality, and long lifetimes. Combining sensing and self-healing functionalities will result in batteries with a predictable lifetime and documented state of health, state of safety, and usage history. Smart functionalities will enable better acceptance of used cells in primary and secondary applications.
With its two research areas, Theme II will address the need for safe and long-lived batteries.
