文摘
- •
A coupled dislocation mechanical model based on diffusion kinetics is developed.
- •
Various electrochemical Biot numbers are considered as the charge conditions.
- •
Dislocation work hardening stress relieves diffusion-induced radial stress partially.
- •
The effect of dislocation strain energy on total strain energy is discussed.
- •
A theoretical method declines the probability of fracture and prolongs battery life.
