Solution combustion synthesis of layered LiNi0.5Mn0.5O2 and its characterization as cathode material for lithium-ion cells

Nanomaterials via solution combustion synthesis: a step nearer to controllability

“…The fuel initiates the combustion reaction with metal nitrates at low ignition temperatures. [43][44][45][46] Complicated Garnets are also widely synthesized by SCS. 4 > 1 or 4 < 1 means one of the reactants is excess in the combustion system.…”

Synthesis of Spinel LiNi0.5Mn1.5O4 by a Wet Chemical Method and Characterization for Lithium-Ion Secondary Batteries

“…22) LiNi 0.5 Mn 0.5 O 2 has a rhombohedral layered structure with space group R3m, with lithium and transition metal ions in a close-packed oxygen array, leading to the formation of lithium and transition metal layers. 25) About 8-10 at.% of nickel and lithium ions can interchange their sites in the layered structure, which is often referred to cation mixing. 25) The electrochemical performance is strongly dependent on the synthesis procedure.…”

Various synthesis methods such as solgel method, 17),29),30) solid-state method, 31)34) molten salt method, 35) co-precipitation, 1),21),36),37) ultrasonic spray pyrolysis method, 23) hydrothermal synthesis, 38) etc., have been used to synthetize LiNi 0.5 Mn 1.5 O 4 .…”

Structural and conductivity studies of LiNi0.5Mn0.5O2cathode materials for lithium-ion batteries

“…So, LiNiO 2 is a promising alternative to LiCoO 2 . Studies on cationic substitution, including Fe, Mn, Al, Mg, Co/Al and Co/Mg for Ni are an attempt to stabilize the layered structure of the material [9][10][11][12][13][14][15]. In the electronic stabilization approach, Mn is partially substituted by Ni in equal concentration, such as 1:1 in LiNi 0.5 Mn 0.5 O 2 compound.…”
