Title:
Causes of Failure Analysis of Lithium Iron Phosphate Batteries
Description:
The large-sized LiFePO4 cannot fully delithiate at the end of charging, while the nano-structured LiFePO4 can reduce the anti-site defects, but it can cause self-discharge due to its high surface. At present, the most commonly used binder is PVDF, which may react at high temperature, dissolve in the non-aqueous electrolyte, and is insufficiently flexible, which has an impact on the capacity loss and shortened cycle life of LiFePO4. In addition, the current collector, diaphragm, electrolyte composition, production process, human factors, external vibration, and shock will affect the performance of the battery to varying degrees. – PowerPoint PPT presentation
