Abstract

In the present work, we have reported the electrochemical performance of xLi2MnO3-(1-x)Li(Mn0.375Ni 0.375Co0.25)O2 (0.0 ≤ × ≤ 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 and excellent capacity retention up to 50 cycles. Our work will pave way to explore Li2MnO3 rich (x ≥ 0.5) integrated cathodes to economic environmentally benign manganese rich, high voltage, high capacity lithium ion batteries.
