Mechanical Stress and Electrochemical Cycling Coupling in Carbon Fiber Electrodes

Mechanical Stress and Electrochemical Cycling Coupling in Carbon Fiber Electrodes 

5583 to 0.6661 mA as the applied strain increased [54]. The peak currents were increased by altered kinetic parameters, especially dilTusivity. In other words, the external load changes the kinetic parameters of battery electrode materials and battery functions. One reason that the diffusivity varies in strained carbon fibers may be the deformation of microstructures. The alteration of diffusion path due to rigid rotation of crystaUites under tension might be an important cause of the change in diffusivities. 

Recently, computer simulation of a whole cell under mechanical stresses has received increasing attention because of the critical effects of stresses on battery life. This section introduces relevant schema used in two recent publications [55, 56]. 

The models consist of three major parts macroscale, microscale, and mesoscale. In the macroscale calculation, transport equations are used to describe mass and 

When the Maxwell-Stefan equation with the thermodynamic pressure term substituted with the hydrostatic stress,
