These Li-ion batteries contain high energy density cathodes based on transition metal oxides. Among numerous investigated potential materials, the LiNi<sub>1\/3<\/sub>Mn<sub>1\/3<\/sub>Co<sub>1\/3<\/sub>O<sub>2<\/sub> cathode has been shown to deliver the best performance at a high potential of 4.5 V versus Li\/Li+ with high reversible capacity.<\/p>\n<p>                                                                                However, at such high potentials, the carbonate species in commercial electrolytes\u2014ethylene carbonate and diethyl carbonate\u2014undergo excessive oxidative decomposition. This, in turn, forms a thick cathode electrolyte interphase (CEI) on the cathode surface, severely compromising its performance. Consequently, researchers have explored electrolyte additives as a way to restrict performance degradation by masking and stabilizing the cathode surface. However, currently available options pose safety and environmental hazards.<\/p>\n<p>Recently, a team of researchers, led by Professor Noriyoshi Matsumi from Japan Advanced Institute of <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a> and <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">Technology<\/a> (JAIST), microbially synthesized 2,5-dimethyl-3,6-bis(4-aminobenzyl)pyrazine (DMBAP), a bio-based compound, as a potential additive for stabilizing the LiNi<sub>1\/3<\/sub>Mn<sub>1\/3<\/sub>Co<sub>1\/3<\/sub>O<sub>2<\/sub> cathodes.

Their findings have been published in <i>Scientific Reports<\/i>.<\/p>\n<p>&#8220;Although biomass-derived materials attract both researchers and the society in <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a>, their applications in electric devices, including lithium-ion batteries, are still limited. This study focuses on novel microbial metabolites, particularly the unique pyrazine-derived diamine DMBAP from the gene cluster of Pseudomonas fluorescens SBW25, discovered in collaboration with Prof. Masuo. Its role as an electrolyte additive could impact the fields of sustainability and smart-cell industry,&#8221; explains Prof. Takaya, speaking of the motivation behind the study.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/stabilizing-lithium-io-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/stabilizing-lithium-io-1.jpg\" data-sub-html=\"Band energy comparison between the electrolyte components, ethylene carbonate (EC), diethyl carbonate (DEC), and DMBAP additive, respectively with their corresponding density functional theory-optimized structures.

This allowed it to be oxidized easily at the cathode surface and form a protective layer over it. In addition, the diamine in DMBAP prevented the dissolution of CEI.<br \/>\n                                            <!-- Google middle Adsense block --><\/p>\n<p>The team additionally performed a detailed electrochemical evaluation of DMBAP for further analysis. The HOMO band energy was confirmed using linear sweep voltammetry, while X-ray photoelectron spectroscopy revealed C\u2212N=C peaks indicative of oxidative electropolymerization. <\/p>\n<p>Cyclic voltammetry and charge-discharge studies showed that the DMBAP additive stabilized the LiNi<sub>1\/3<\/sub>Mn<sub>1\/3<\/sub>Co<sub>1\/3<\/sub>O<sub>2<\/sub> cathode by improving the battery&#8217;s rate capability, cyclic stability, coulombic efficiency, and capacity retention. Moreover, dynamic electrochemical impedance spectroscopy experiments demonstrated the formation of a low interfacial resistance CEI.<\/p>\n<p>Based on these results, the team concluded that the DMBAP underwent sacrificial oxidative decomposition, forming an organic passivation armor on the cathode surface. This, in turn, restricted excessive electrolyte degradation and stabilized the structure of transition metal oxides on the cathode. <\/p>\n<p>In effect, this virtuous phenomenon increases the operating potential window of LiNi<sub>1\/3<\/sub>Mn<sub>1\/3<\/sub>Co<sub>1\/3<\/sub>O<sub>2<\/sub> cathode to 4.5 V versus Li\/Li<sup>+<\/sup>. Moreover, the stabilizing effect of DMBAP on the battery system was remarkable for both half-cell and full-cell configurations.<\/p>\n<p>&#8220;Microbially prepared pyrazine-amine compound DMBAP will boost the performance of lithium-ion secondary batteries essential for next-generation electric vehicles and drones. It will also promote the wider utilization of bio-based resources in the huge-scale automotive industry. Further, bio-based materials for energy storage devices will doubly reduce carbon dioxide emissions\u2014during manufacturing and operation,&#8221; says Prof. Matsumi, discusses the future benefits of their work.\n                                                                                                                            <\/p>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Agman Gupta et al, Microbial pyrazine diamine is a novel electrolyte additive that shields high-voltage LiNi1\/3Co1\/3Mn1\/3O2 cathodes, <i>Scientific Reports<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s41598-022-22018-1\">DOI: 10.1038\/s41598-022-22018-1<\/a><\/p><\/div>\n<p>                                                Provided by<br \/>\n                                                                                                    Japan Advanced Institute of Science and Technology<\/p>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Stabilizing lithium-ion batteries with a microbially synthesized electrolyte additive (2022, November 30)<br \/>\n                                                 retrieved 30 November 2022<br \/>\n                                                 from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-11-stabilizing-lithium-ion-batteries-microbially-electrolyte.html<\/p>\n<p>                                            This document is subject to copyright.
