6. Experimental Characterization of Electrodes and Multi-Scale Modeling of Swelling Induced Stresses in Lithium-ion Batteries
Abstract : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. READ MORE

7. A Fracture Mechanics Approach to Study Hydrogen Embrittlement in High Strength Martensitic Steels
Abstract : High strength steels that are subjected to hydrogen experience embrittlement where the mechanical properties are reduced, and premature failure of components may occur. Although the phenomenon has been recognized for over 150 years, it is not clear what drives embrittlement. READ MORE

9. Discrete element modelling of the mechanical behaviour of lithium-ion battery electrode layers
Abstract : Since their introduction in the late 20th century, lithium-ion batteries have become the leading battery technology for portable devices and electric vehicles due to their high energy density and rechargeability. However, the increasing demand for a longer battery life span is hindered by the fading of the battery’s charge capacity over prolonged use. READ MORE
