文摘
- •
The negative electrodes of cycled LFP/graphite cells are investigated.
- •
The PVDF binder at the graphite anode side does not degrade during cycling.
- •
The volume of graphite particles increase by 30% after 800 cycling at 1C-rate.
- •
The d-spacings of the graphite particles do not change after cycling.
- •
The particle size increase is due to the void formation within graphite particles.
