| description | <p>Lithium manganese oxide (LMO), carbon nanotubes (CNTs), and graphene nanoplatelets (GNPs) were used to develop nanocomposites using a microwave-assisted chemical precipitation method and characterized using various techniques. The process provides better control over morphological features and proficient choice of cost-effective precursors. This research aims to increase the active surface area and the number of lithium-ion (Li<sup>+</sup>) intercalation sites using the CNTs and GNPs in LMO to improve its electrochemical performance. The structural analysis shows that the average crystallite size is 50 nm without using any capping agent during the synthesis process, which is smaller when compared to pristine LMO. The electrochemical studies demonstrate that the incorporation of carbon nanostructures (CNTs and GNPs) boosts the rate capabilities and cyclic performance of LMO. The LMO-CNTs and LMO-GNPs have an excellent rate capability of 124 and 127 mAhg<sup>−1</sup> at 0.1C, sustained at 115.6 and 118.5 mAhg<sup>−1</sup> at 10C, respectively. Cycling efficiency is also improved, with LMO-CNTs and LMO-GNPs having an initial capacity of 124 and 127 mAhg<sup>−1</sup> decreasing to 112 and 114 mAhg<sup>−1</sup>, respectively, after 50 cycles. Compared to pure LMO, the increased electrochemical performance of LMO nanocomposites is due to the introduction of carbon nanostructures (CNTs and GNPs).</p> <h2>Other Information</h2> <p>Published in: Energy Storage<br> License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br> See article on publisher's website: <a href="http://dx.doi.org/10.1002/est2.202" target="_blank">http://dx.doi.org/10.1002/est2.202</a></p> |
