Abstract

Systems and methods for aromatic macrocyclic compounds (Phthalocyanines) as cathode additives for inhibition of transition metal dissolution and stable solid electrolyte interphase formation may include an anode, an electrolyte, and a cathode, where the cathode comprises an active material and a phthalocyanine additive, the additive being coordinated with different metal cationic center and functional groups. The active material may comprise one or more of: nickel cobalt aluminum oxide, nickel cobalt manganese oxide, lithium iron phosphate, lithium cobalt oxide, and lithium manganese oxide, Ni-rich layered oxides LiNi 1−x M x O 2 where M=Co, Mn, or Al, Li-rich xLi 2 MnO 3 ( 1 −x)LiNi a Co b Mn c O 2 , Li-rich layered oxides LiNi 1+x M 1− O 2 where M=Co, Mn, or Ni, and spinel oxides LiNi 0.5 Mn 1.5 O 4 . The phthalocyanine additive may include one or more of: cobalt hexadecafluoro phthalocyanine (Co-Pc-F), dilithium phthalocyanine (Li-Pc), cobalt(II) phthalocyanine, nickel(II) phthalocyanine-tetrasulfonic acid tetrasodium salt, titanium(IV) phthalocyanine dichloride, manganese(II) phthalocyanine, zinc phthalocyanine, aluminum phthalocyanine chloride, Iron(II) phthalocyanine, and silicon phthalocyanine dichloride.
