Performance of Wet Chemical Synthesized xLi₂MnO₃-(1-x)Li(Mn_0.375Ni_0.375Co_0.25)O₂(0.0 ≤ x ≤ 1.0) Integrated Cathode for Lithium Rechargeable Battery

In the present work, we have reported the electrochemical performance of xLi 2 MnO 3 -(1-x)Li(Mn 0.375 Ni 0.375 Co 0.25 )O 2 (0.0 ≤ x ≤ 1.0) integrated cathodes for high energy density lithium rechargeable batteries. For x = 0.5 cathode we have reported discharge capacity of 290 mAhg −1 with capacity retention ∼76% after 50 cycles at 10 mAg −1 . It is remarkable to find x = 0.75 to yield discharge capacity ∼235 mAhg −1 and excellent capacity retention up to 50 cycles. Our work will pave way to explore Li 2 MnO 3 rich (x ≥ 0.5) integrated cathodes to economic environmentally benign manganese rich, high voltage, high capacity lithium ion batteries.
