Blog – Recap – The Battery Show North America

  • Recap – The Battery Show North America – Novi, MI (USA) – September 13-15, 2022
    Posted on 2022-09-19

  • Many thanks to Adrian Tylim from Blue Solutions for the informative joint session at the The Battery Show North America on 'Divergent Approaches to Solid & Semi-solid Batteries for EVs'.
  • They have deployed solid-state batteries in e-buses together with Mercedes-Benz AG based on lithium metal electrodes that might soon become thinner & cheaper (collaboration with Li-Metal).
  • E-magy and Ionic Mineral Technologies presented novel Si active material architectures while Prologium Technology explained that progress has been achieved towards increasing the Si content in its negative electrodes towards 50-100% in combination with its hybrid electrolyte (presumably based on oxide or phosphate and polymers).
  • The novel stacked high energy (liquid electrolyte) cell architecture by ENOVIX is manufactured based on their micro-scale electrode positioning capability (with the help of Laser-patterned positioning pins). Such high yield manufacturing capabilities might eventually enable manufacturing of bipolar solid-state Li-ion battery cells.

    Advantages and Disadvantages of Various Solid & Semi-solid Electrolytes: 1) Sulfides; 2) Polymers; 3) Mixtures Between Ion-conducting Salts / Organic Molecules / Inert Inorganic Support Materials; 4) Oxides / Phosphates; 5) Halides; 6) Thin-film (Vacuum Deposition, e.g. of LiPON); 7) Eutectic Salts
