7 августа состоится вебинар фирмы Bruker, посвященный исследованию твердых электролитов методами АСМ (In-situ Study of Solid Electrolyte Interphase using PeakForce Tapping® Mode AFM in Glove-box)
Intensive study has been directed to understand the role of solid electrolyte interphase (SEI) formed on lithium battery anodes. It is believed to be accountable for the charge/discharge properties, cycle-ability and lifetime of the battery. In-situ AFM has been used to directly visualize the formation and evolution of SEI on the nanometer scale, but its widespread use has been hindered by the lack of stringent environmental control required for lithium battery materials.
IN THIS WEBINAR WE WILL:
- Describe the setup that enables in-situ observation of SEI formation and probing of its mechanical properties: Dimension ICON AFM integrated in an argon-filled glove box with O2 and H2O below 1ppm, which is powered by the PeakForce Tapping mode to reveal not only the morphology evolution but also quantitative nano-mechanical properties of the SEI layer.
- Demonstrate its fitness in monitoring SEI formation on highly ordered pyrolytic graphite (HOPG) upon charging/discharging in 1M LiPF6 EC:DEC.
- Showcase its relevance in the search of high capacity anode alternatives-Si Anode. The stability of the Solid Electrolyte Interphase (SEI) is critical in rechargeable Li-ion batteries. This issue is particularly challenging in silicon, which has a high Li capacity and a correspondingly large volume expansion. Fresh data will speak to the promise of this new tool in advancing lithium battery technology.
WHO SHOULD ATTEND:
- Lithium battery researcher / maker in particular
- Electrochemistry user in general: battery, electroplating, corrosion, bio-electrochemistry
