Embedding smart functionalities into battery cells (embedding sensing and self-healing functionalities to monitor and self-repair battery cells) (Batteries Partnership)

The target of this call is to embed sensors and self-healing functionalities into single battery cell, with sensors being capable to detect defective operation and trigger self-repairing functionalities via the Battery Management System (BMS).

Proposal should aim at a combined approach with the development of sensors capable of continuous, long term operation within the cell and on the development of self-healing functionalities which can be triggered by external stimulus. Sensors and self-healing functionalities need to be adapted to detection of the critical degradation processes during cell electrochemical or chemical ageing. Different battery chemistries can be addressed with a focus on most critical degradation processes.

Proof of concept of coupling sensors and self-healing agents via BMS should be demonstrated. Clear benefit of embedding smart functionalities into battery cells should be demonstrated and approach needs to be adaptable to battery cells mass production processes and not hinder subsequent recycling process. Estimation of QRL over the life span should be assessed and the competitive advantage over alternative approaches like replacement or recycling or second-use should be demonstrated.

Building upon the BATTERY 2030+ roadmap, this call topic addresses the need to develop new sensors and self-healing functionalities which can give the batteries of the future increased life-time, efficient re-use and better commercial success. The benefit of these innovation on the global battery safety should be demonstrated. The proposal should also cover the contribution and collaboration to the BATTERY 2030+ large scale initiative.

This topic implements the co-programmed European Partnership on ‘Towards a competitive European industrial battery value chain for stationary applications and e-mobility’.
