•Efficient cathode LiMn2O4 with Asphalt and Bituminous were prepared to be tested as in (LIB’s).•High porosity and large surface area of extracted carbon proven promising choice for the dendrites minimization.•Reasonably good LIB’s capacitance of bituminous composite was found as Csp 586 Fg−1over asphalt Csp 517 Fg−1 .•This novel composite renders less ohmic resistance by resaonably improving leakage current of LIB’s. Lithium ion battery is a promising energy storage device because of high energy and power densities. This study aims at the fabrication of a low-cost efficient cathode material for the enhanced battery performance with reasonably higher power and energy density over its contemporary cathode materials. In this regard, LiMn2O4/asphalt and LiMn2O4/bituminous coal based composite materials were synthesized employing co-precipitation and sol–gel approaches and evaluated as electrode material. Results revealed that LiMn2O4/bituminous coal composite, owing to remarkably high specific capacitance as Csp 586 Fg−1 at a scan rate 5 mVs−1, could be a promising economical cathode material for the energy density enhancement of a battery in comparison to LiMn2O4/asphalt composite.
