In-situ SEM: Seeing Battery Cycling in Action
Real-time Observation of Morphology Changes in SiOx Anodes for Lithium-ion Batteries
The Zaghib Group at Hydro-Québec has used in situ SEM to see SiOx particles grow and shrink during cycling. SiOx is a promising anode material for Li-ion batteries due to a high theoretical specific capacity of 1338 mAh/g and less volume change than Si upon charge-discharge. Analysis of the morphology changes in SiOx particles provides insight into the failure mode associated with capacity fade on cycling. [Read more…]
