Development of a Representative Volume Element of Lithium-ion Batteries for Thermo-mechanical Integrity
The importance of Lithium-ion batteries continues to grow with the introduction of more electronic devices, electric cars, and energy storage. Yet the optimization approach taken by the manufacturers and system designers is one of test and build, an approach that nearly every other industry has long abandoned. A computational model is required to reduce the expensive build-test cycle and allow ...
متن کاملAn analytical electro-thermal model for Lithium-ion Batteries
Introduction Batteries with lithium-ion chemistry are the preferred candidate to power hybrid and electric vehicles (HEVs), due to their high power density (up to 150 Wh/kg), short charging time, minimal memory effects and selfdischarge (around 5% per month), and long cycling life [1]. Nonetheless, thermal management of large-scale lithium-ion (Li-ion) batteries during high current charge and d...
متن کاملDeformation and fracture of silicon electrodes in lithium-ion batteries
We have performed a number of experiments to examine the mechanical behavior of amorphous silicon electrodes of lithium-ion batteries. In particular, we have measured the fracture energy of lithiated silicon thin-fi lm electrodes as a function of lithium concentration. The fracture energy is found to be similar to that of pure silicon and essentially independent of the concentration of lithium....
متن کاملReactive Flow in Large-deformation Electrodes of Lithium-ion Batteries
An electrode in a lithium-ion battery may undergo inelastic processes of two types: flow and reaction. Flow changes the shape of the electrode, preserves its composition and volume, and is driven by the deviatoric stress — a process similar to the plastic flow of a metal. By contrast, reaction changes the composition and volume of the electrode, and is driven by a combination of the mean stress...
متن کاملAnalytical Solution of Stress Distribution ona Hollow Cylindrical Fiber of a Composite with Cylindrical Volume Element under Axial Loading
The study of the stress distribution on a hollow cylindrical fiber placed in a composite material is considered in this work and an analytical solution for this stress distribution has been constructed. Finally some parameters such as fiber’s thickness and fiber’s length are considered and their effects on the distribution of stress have been investigated. For finding the governing relations, c...
