Performance of wet chemical synthesized xLi₂MnO ₃-(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 xLi₂MnO₃-(1-x)Li(Mn_0.375Ni _0.375Co_0.25)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.
