Effect of charging/discharging on plasticity and fracture in Si anodes for batteries

Seyed Mostafa Khosrownejad

Lithium-ion batteries provide the power for portable electronics and found many other interesting applications. It is desirable to design batteries with high energy density and long cycle life. Silicon is among the highest Li-storing anode materials in bat ...

Model for charge/discharge-rate-dependent plastic flow in amorphous battery materials

William Curtin, Seyed Mostafa Khosrownejad

Plastic flow is an important mechanism for relaxing stresses that develop due to swelling/shrinkage during charging/discharging of battery materials. Amorphous high-storage capacity Li-Si has lower flow stresses than crystalline materials but there is evid ...

Crack growth and fracture toughness of amorphous Li-Si anodes: Mechanisms and role of charging/discharging studied by atomistic simulations

William Curtin, Seyed Mostafa Khosrownejad

Fracture is the main cause of degradation and capacity fading in lithiated silicon during cycling. Experiments on the fracture of lithiated silicon show conflicting results, and so mechanistic models can help interpret experiments and guide component desig ...

Ridge waveguide metamaterial filters

Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam, Seyed Mostafa Khosrownejad

Ridge waveguide metamaterial filter comprising at least one ridge waveguide, at least one microwave or millimeter wave metamaterial-filter and at least one transition structure. The metamaterial-filter comprises a host waveguide including a plurality of ra ...
