The Materials Science and Environmental Engineering unit at Tampere University is expanding its expertise in the handling, production, and processing of electrolyte and electrode materials for the Gen4a, 4b of lithium-ion batteries.

The battery materials necessitate an argon atmosphere with impurity levels, such as O2 and H2O, kept below 1 ppm. To achieve this, we have acquired a new glovebox designed to operate within an argon atmosphere. This system will be dedicated to research purposes, enabling us to explore and develop the next generation of battery materials and cells. 

The system comprises six gloves, all positioned on the same side. It was constructed by expanding a four-glove system with a two-glove system through a partition wall. This configuration enables material processing in one section of the glove box and cell assembly in the other. Dr. Amandeep Singh believes that the current glovebox setup will empower us to: 

  • Test new materials for the next generation of Li-ion batteries,  
  • Scale up the production of researched anode materials,  
  • Participate in cell assembly. 

Dr. Singh confidently asserts, "Our expertise in anode material R&D, battery testing, post-mortem analysis, and the expansion of infrastructure for battery material investigations could position us among the leading contributors to European battery technology. This, of course, depends on the acceptance of our project funding applications and further support from our university in enhancing battery research resources."
