Abstract: Ni-rich layered LiNi 0.84 Co 0.10 Mn 0.06 O 2 cathode material was modified by doping with vanadium to enhance the electrochemical performances. The XRD, FESEM and XPS analyses were indicated that the vanadium is successfully doped in the crystal lattice of LiNi 0.84 Co 0.10 Mn 0.06 O 2 with high crystallinity. 0.05 mol% vanadium… Show more

“…According to the reported articles, the strategy of element doping has been widely used to enhance the reversible capacity of cathode materials at high voltage. 10 Abundant cations doping (Al, 11 W, 12 V, 13 Mg, 14 Zr, 15 Nb 16 ) and anion modification (F, 17 N 18 ) have been examined by most of researchers all over the world over the past few years. Li et al 11 prepared homogeneously Al-doped NCM811 via using a co-precipitation method.…”

“…One of the most important issues relating to lithium-ion batteries (LIBs) is the development of new cathodes with higher energy densities than commercially used LiCoO 2 , Li(Ni, Co, Mn)O 2 (NCM), and Li(Ni, Co, Al)O 2 (NCA) 1 – 7 . Fundamentally, the capacity of most cathodes can be attributed to the cationic redox of transition metals such as Co, Ni, and Mn in the structure.…”

“…In some studies, surface modification (i.e., surface coating and doping) has been utilized to stabilize the interface and address the aforementioned challenges. 2,8,14 Surface doping, by substituting the original ions with cations or anions such as B, 11 Ti, 7 Ta, 15 Ce, 16 V, 17 Mg, 18 and F, 19,20 aims to ensure steady the structure of Ni-rich cathode and enhance the lithium-ion diffusion kinetics. Surface coating is also an effective approach to achieve superior electrochemical performances due to protecting the Ni-rich cathode from HF, cleaning the detrimental surface functional groups (i.e., Li 2 O, LiOH, or Li 2 CO 3 ) and stabilizing the cathode/electrolyte interface as the conducting media for Li ion and electron.…”

“…As a result, Ni-rich cathode suffers from poor cycling performance and fast voltage drop, particularly at high cutoff voltages. In some studies, surface modification (i.e., surface coating and doping) has been utilized to stabilize the interface and address the aforementioned challenges. ,, Surface doping, by substituting the original ions with cations or anions such as B, Ti, Ta, Ce, V, Mg, and F, , aims to ensure steady the structure of Ni-rich cathode and enhance the lithium-ion diffusion kinetics. Surface coating is also an effective approach to achieve superior electrochemical performances due to protecting the Ni-rich cathode from HF, cleaning the detrimental surface functional groups (i.e., Li 2 O, LiOH, or Li 2 CO 3 ) and stabilizing the cathode/electrolyte interface as the conducting media for Li ion and electron. , Over the past decade, metal oxides (TiO 2 , ZnO, SiO 2 , ZrO 2 , Al 2 O 3 , and V 2 O 5 ), fluorides (AlF 3 ), and phosphates (MnPO 4 ) have been used as coating layers materials for LiNi 1– x – y Co x Mn y O 2 to protect the structure of the Ni-rich cathode from electrolyte.…”
