About the Seminar:

Sodium-ion batteries (SIBs) present a promising alternative to lithium-ion batteries (LIBs) by reducing reliance on critical materials like Li, Ni, and Co, while still fulfilling energy storage needs. Research into electrodes for NIBs is critical for long term development and commercialization. A significant challenge to commercialization is the loss of Na ions to the solid electrolyte interface (SEI). The SEI affects specific capacity, stability of the electrode, and battery lifetime. Presodiation treatments can help mitigate this irreversible Na loss by adding Na ions into the electrode before cycling. Direct contact presodiation is the most promising method due to its ease however it is difficult to control the degree of presodiation. This seminar will investigate “Presodiation Strategies and Their Effect on Electrode−Electrolyte Interphases for High-Performance Electrodes for Sodium-Ion Batteries”, the proposed hypotheses, questions left unanswered, and steps moving forward.
