Zusammenfassung:	A cathode composition is provided. The composition includes particles having the following formula Li[Lix(NiaMnbCoc)1-x]O2, where 0 < x < 0.3, 0 < a < 1, 0 < b < 1, 0 < c < 1, a+b+c=1, a/b ≤ 1. The composition further includes a coating composition having the formula LifCog[PO4]1-f-g (0 ≤ f < 1, 0 ≤ g < 1). The coating composition is disposed on an outer surface of the particles.
