Project Overview
The Centre for E-Mobility & clean Growth (CECG) is one of 10 organisations from six European countries to have joined forces and secured the significant funding under the umbrella of the Horizon Europe Programme. While currently generation lithium-ion (Li-ion Gen 3) chemistries dominate the market for rechargeable batteries, future generations of chemistries offer promising step-changes and improvements.
The project aims to develop and implement self-healing concepts and materials in the critical battery components used in conventional Li-S batteries and extrapolate the ideas to develop a new class of self-healing structural batteries based on Li-S by investigating at the cell & component level. It will be built a toolbox of self-healing materials, sensors, and a customized Battery Management System to maximize the performance of the produced Li-S battery in terms of Quality, Reliability, and lifetime and to avoid or repair occurring damages; The BMS's goal is to govern the flow of energy to and from the battery system, monitoring sensor data with computational methods to identify events indicating degradation, as well as initiate self-healing actions.
Project Objectives
The goal is to develop a proof of concept of coupling advanced sensors, passive self-healing components and active self-healing agents to be triggered via a Smart BMS through the continuous monitoring of the data obtained from sensors for Li-S batteries. The resulting BMS will integrate data processing capabilities to optimize various countermeasures to be triggered that will minimize the negative impacts in batteries usage, typically (1) mechanical degradation, including electrode cracking or loss of electrical connectivity, and (2) chemical/electrochemical degradation, such as deposition of inactive resistive phases onto anode or current collector corrosion. Moreover, a Digital Twin will be built to contain advanced cell models to allow further analysis of the self-healing battery behaviour. The data obtained from novel sensors and the BMS will feed the advanced models that will provide a framework for more accurate SoX estimations and battery life-time prediction.
Impact Statement
The resulting solution will revamp the European sector of rechargeable batteries with high round-trip efficiency energy storage for numerous applications, as specified in the EU Green Deal, consequently promoting innovative ideas needed to develop future sustainable batteries which demand fewer resources and create the groundwork for EU competitiveness. The project will be aligned with the Battery2030+ large-scale initiative within their "Integration of smart functionalities" theme, which supports sensing and self-healing
The HEALING BAT project will develop a proof of concept for coupling advanced sensors, passive and active selfhealing agents, to be triggered via a Smart BMS. This is fully in line with the expected outcomes and impacts relevant for the suitable topic. HEALING BAT has placed the focus on generating impact: to market next-generation Li-S batteries systems and emerging technologies by embedding sensors and self-healing functionalities at cell level. Through the implementation of the project, it is aimed at supporting a more competitive and sustainable battery manufacturing industry in Europe by means of obtaining increased, quality, reliability and life of Li-S battery systems. According to the acknowledged state-of-the art, even though Li-S batteries offer higher energy density visà-vis current Li-ion technologies, the loathsomely structural changes during charging processes result in mechanical fracture problems which do not allow their development at industrial scale
