Revealing the voltage decay of LiMn0.7Fe0.3PO4 cathodes over …
Using LiMn 0.7 Fe 0.3 PO 4 as a model, the increasing non-synchronous reaction among particles causes the voltage decay. •. Inhomogeneity between particles is autoaccelerating during lithiation, accumulating with cycling. •. The voltage decay is greatly diminished for the LiMn 0.7 Fe 0.3 PO 4 with electrode additive.
