As-Fabricated solid-state asymmetric super capacitor with specific capacitance 46-22 fg-1 at varying current densities. As-Fabricated as-sourced solid-state asymmetrical super capacitor with power density 499 wk kg-1 with high specific specific energy density 25 whk kg-1. Solid-state asymmetric asymmetric super capacitor maintains 88% of capacitance after 7,500 cycles which is another advantage and suitable for use in commercial applications. Electrical impedance spectrometry (ESS) experiments were carried out on all materials produced in semi-cell, 3 electrolyte and 2 electrolyte systems. LMNCO-950 electrodes represented the lowest Rs values at 2.18 and Rct values at 39.18, demonstrating the material’s relatively stable and excellent properties. The Li+ co-efficient of the LMNCO950 electrode at 2.783 x 10-15 is significantly higher than that of the LMNCO-800, LMNCO-900, and LMNCO-1000 samples at 1.367 x 10-15, 2.767 x 10-15 and 1.647 x 10-15 respectively. The H-CMO Rct values obtained at the 3rd and 500th cycles were 285, 396, 267, and 355 for the P-CMO and 186, 262, and 182, respectively, for the GW-PP-CMO electrode, which outperformed the two other electrode models in capacity retention and showed a lower Rct value.The best Li- ion diffusion coefficient, the lowest Rs values, and the very stable material interfaces (even after extended cycling without decay) are all indicative of the material's relatively stable properties. The low Rct values are due to the porous, small particle size, high active surface area, and Mn based nano structures that support the greater electrode. Another method is to transfer charged particles more quickly between the electrode and the electrolyte. The properties of the material improve the electrochemical properties by increasing the specific capacitance and improving the capacity retention properties. The cyclic stability of the electrode is essential for energy storage applications such as renewable energy storage systems or hybrid electric vehicles.
