Our work package leader - Adrien Mery
Within the SOLIDBAT project, Adrien Méry from AMPERE leads Work Package 6, dedicated to assessing the electrochemical performance and safety of solid-state battery cells. His team evaluates 1 Ah and 5 Ah cells to validate their reproducibility, cycling stability, and resistance to thermal runaway — providing key data that supports modelling and design optimisation across the project.

Which are the challenges of your WP(s)?
WP6 will assess electrochemical performances and safety of 1 Ah cells according to the defined specifications in WP2, with the aim of: i) assessing the performances and cycling life of full cells; ii) providing knowledge of the reaction mechanisms in normal and abuse conditions; iii) providing experimental evidence to the mechanisms involved in ageing of the SSBs; iv) assessing safety behaviour of the SSB at cell level; and v) supplying the experimental results required for models development in WP5. Additionally, WP6 will assess 5 Ah cells, to confirm the reproducibility of the process and the repeatability of the performances, and mini-modules of two 5 Ah cells to assess the risk of thermal runaway propagation and safety in module configuration.
Challenges are about the quality of the testing protocols and the reproducibility of the testing conditions/environment by the several partners involved. However, I think the main challenge is coming from WPs linked to material/electrolyte development and manufacturing of reproducible cells. The success of WP6 is strongly dependent on the achievements of these WPs as we need to have several reproducible 1 Ah and 5 Ah cells to perform the full electrochemical and safety assesment of the SOLIDBAT technology.

Which achievements do you foresee?
Even if the targets are high and possibly hard to achieve, I think we all hope to reach a maximum of the KPIs of the SOLIDBAT project (Energy densities, cycling stability, safety…).

Which synergies do you expect to have with partners?
WP6 is strongly linked to WP2 (definition of testing protocols, cell design and requirements), WP5 (modelling) where data coming from both WP5 and WP6 will be exchanged and also WP4 (prototyping and manufactuirng of the 1 and 5 Ah cells). Basically, synergies are expected to be with almost all the partners of the project

A personal perspective: what do you like/enjoy/expect from the experience of being a WPL?
As an industrial involved in the EV application, being a WPL responsible for evaluating the final cells of the SOLIDBAT project is interesting because it allows to have data/results on an innovative technology that could have a future industrial application.
Personally, being WPL, and more generally being part of a European project, allows working with diverse teams from different countries and disciplines (academic and industrial), expanding one’s network and staying informed about new innovations in the field of batteries. Also, being WPL helps to improve its skills in terms of team and project management.
