Li1.2Ni0.15Mn0.55Co0.1O2 (LMR NMC) is synthesized by solution combustion method followed by LiF coating onto LMR NMC by solid state synthesis. The electrochemical performance of the pristine LMR NMC and corresponding F-doped samples as cathodes for Lithium ion Batteries (LIBs) are investigated by galvanostatic charge-discharge cycling and impedance spectroscopy. The fluorine doped cathodes deliver high capacity of ∼300 mAh g−1 at C/10 rate (10–20% greater than the pristine LMR NMC cathodes), have high discharge voltage plateau (>0.25 V) and low charge voltage plateau (0.2–0.4 V) compared to pristine LMR NMC cathodes. Beside, irreversible capacity, voltage fade, capacity loss are significantly reduced in-relation to the pristine LMR NMC electrodes. LiF coating onto LMR NMC, partially replaces M[sbnd]O bonds of the material by M[sbnd]F bonds, thus increasing the interfacial and structural stability. Besides, the manuscript describes possible replacement of aluminium current collector with 3D carbon fiber current collector which delivers high capacity of >200 mAh g−1 at 1C rate, good capacity retentions for over 200 cycles. The study opens a possibility for LMR NMC cathode material which has almost double the capacity of currently used cathodes, can be a possible substitute cathode for LIBs used in electric vehicles. © 2017
