description | [Image: see text] Sodium-ion batteries (NIBs) are promising candidates for specific stationary applications considering their low-cost and cost-effective energetic property compared to lithium-ion batteries (LIBs). Additional cost cutbacks are achievable by employing natural materials as active cathode materials for NIBs. In this work, we report the use of natural pyrolusite (β-MnO(2)) as a precursor for the synthesis of a NaMnO blend (a mixture of layered P2-Na(0.67)Mn(0.85)Al(0.15)O(2) without any doping technique combined with a post-spinel NaMn(2)O(4) without any high-pressure synthesis). The synthesized powder was characterized by XRD, evidencing these two phases, along with two additional phases. Tests for Na-ion insertion registered a reversible discharge capacity of 104 mA h/g after 10 cycles with a well-defined plateau at 2.25 V. After 500 cycles at a C/4 current density, a high Coulombic efficiency between 96 and 99% was achieved, with an overall 25% capacity retention loss. These pilot tests are encouraging; they provide economic relief since the natural material is abundant (low-cost). Desirable, energetic assurances and ecological confirmations are obtainable if these materials are implemented in large-scale stationary applications. The synthesis technique does not use any toxic metals or toxic solvents and has limited side product formation. |
