英文摘要	Nanostructure-LiNi1/3Co1/3Mn1/3O2 (NCMa) has been successfully synthesized via a facile chemistry method using a cheap chelating agent of acetic acid. The NCMa has low cation mixing between Li+ and Ni2+ and exhibits a diameter of 100–300 nm. Specifically, the as-prepared particles NCMa with unique nano structure can increase the contact area with electrolyte, shorten Li+ diffusion path and thus improve the Li+ mobility. In addition, to reduce the adverse effect caused by NCMa, lithium bis(oxalate)borate (LiBOB) instead of LiPF6 has been used as electrolyte salt to enhance the cycling of NCMa, due to the fact that LiBOB will generate relatively little acid in electrolyte. Furthermore, it is interest to note that LiBOB leads to forming a relative stable passivation film on the surface of NCMa cathode. Hence, compared with LiPF6, NCMa will generate remarkable electrochemical lithium storage properties in terms of high capacity, excellent rate capability and ultrastable long-term cycling performance. © 2017 Elsevier B.V.
