An overview on the life cycle of lithium iron phosphate: synthesis
Due to lithium ions having high energy barriers greater than 2.8 eV along directions of [1 0 1] pnma and [0 0 1] pnma, where the energy required to migrate along these two directions is much higher than the energy in the [0 1 0] pnma direction, the distances of llithium ions in these two directions are both greater than 4.5 Å, and there is no continuous LiO 6
