<p>Lithium-ion hybrid capacitors have gained more attention due to their improved energy density, exceeding &gt; 25 Wh kg⁻¹ without sacrificing the power density of the supercapacitors. In this work, we have fabricated a hybrid device employing battery-type conversion materials (Ni-Mn–O composite) as anode and high surface area carbon&#xa0;(HSAC) as cathode. The Ni-Mn–O composite consists of NiMn₂O₄, NiMnO₃, and Mn₂O₃. The battery type NiMn₂O₄, NiMnO₃, and Mn₂O₃ electrode not only enables faradaic storing of Li⁺ ions but also empowers the pseudocapacitive property of the composites. Moreover, the stable 3D framework of spinel-cubic and perovskite structure also facilitates the outstanding transport pathways for Li⁺ ion diffusion. On the other hand, the high surface area carbon (HSAC) demonstrated robust cycling performance, retaining 80% of its capacitance after 5000 cycles. Thus, the Li-ion capacitor utilizes this high surface area carbon as a cathode and pre-lithiated Ni-Mn–O composite (NMO) as anode with an optimized mass ratio of 2:1. The Li-ion capacitor delivers a maximum energy density of 105 Wh kg⁻¹ at the power density of 333 W kg⁻¹ and a maximum power output of 8335 W kg⁻¹ at 23 Wh kg⁻¹. Besides, full-cell LIC maintains 70% retention in capacity with &gt; 99.8% coulombic efficiency up to 10,000 cycles.</p> Graphical Abstract <p></p>
