Synthesis and characterization of blended cathode materials as improvement on the electrochemical performance in Li-ion battery

•Cathode materials via a simple calcination route were obtained.•The electrodes annealed at 850 °C have the better specific capacity and cycling stability.•Mixes phase composite lareyed/spinel LiNi1/3Co1/3Mn1/3O2/LiMn2O4 particles of cathodes material reveal enhanced capacity retention and rate capability.•LiMn2O4 in LiNi1/3Co1/3Mn1/3O2 enhances electrochemical properties.
