- •
Undoped LiMnPO4 was cycled more than 500 times at 55 °C.
- •
Average capacity loss was less than 0.06% cycle.
- •
After ca 550 cycles very fast capacity degradation was observed.
- •
Surface film formation, Mn dissolution and occurrence of Li4P2O7 was observed.
- •
Decomposition starts at local defects in the microstructure of carbon coating.
