Today we celebrate already the 10th Open Access Publication from project PULSELiON. What an achievement by the team! We proudly present the journal article “Understanding mechanical stresses upon solid-state battery electrode cycling using discrete element method”, which has been published already some time ago in the Journal for Energy Storage Materials, Volume 70, on 14 June 2024.
Solid-state batteries (SSBs) often fall behind conventional lithium-ion batteries (LIBs) in performance. Electrochemical cycling protocols, in particular under isostatic compression, present ample opportunities for improvement to mitigate issues like contact loss and aging among numerous other challenges.
The work introduces a novel Discrete Element Method (DEM) workflow to assess the effectiveness of uniaxial and isostatic compression as proceeding electrode preparation on the conductivity and structural integrity of Solid-State Batteries. And shows the impact of mechanical stress during different stages of electrochemical cycling on the microstructure’s integrity to provide valuable insights into electrochemistry-mechanics couplings, which can be challenging to evaluate experimentally.
We are proud of this achievement within project PULSELiON, thanks to the authors from project partner CNRS: Mohammed Alabdali, Franco M. Zanotto, Alain C. Ngandjong, Virginie Viallet, Vincent Seznec and Alejandro A. Franco.
