class="auto" style="max-width:1330px;"><div class="edit"><p><strong>Elektrolytisches Mangandioxid </strong>(EMD) ist eine synthetische Form von Mangandioxid, die durch einen elektrolytischen Prozess hergestellt wird. Aufgrund seiner einzigartigen Kristallstruktur (hauptsächlich vom γ-Typ), seiner hohen Reinheit und seiner außergewöhnlichen elektrochemischen Aktivität dient es als unersetzliches Schlüsselmaterial in der Kathode von Primärbatterien (nicht wiederaufladbar).</p> <p> </p> <p>Seine Hauptanwendungen liegen in Zink-Mangan-Batterien:</p> <p> </p> <p><strong>Alkalische Zink-Mangan-Batterien </strong>: Dies stellt die größte und wichtigste Anwendung von EMD dar. In Alkalibatterien fungiert EMD als aktives Kathodenmaterial und sorgt in Verbindung mit einer Zinkanode und einem Kaliumhydroxidelektrolyten für eine deutlich höhere Kapazität, eine überlegene Hochstromentladungsleistung und eine längere Lagerlebensdauer im Vergleich zu herkömmlichen Leclanché-Batterien (Kohlenstoff-Zink). Die überwiegende Mehrheit der Alkalibatteriekathoden weltweit nutzt EMD.</p> <p> </p> <p><strong>Kohlenstoff-Zink-Batterien (Leclanché). </strong>: EMD wird auch in Hochleistungs-Kohlenstoff-Zink-Batterien verwendet, oft gemischt mit natürlichem Mangandioxid (NMD), um deren Entladefähigkeit zu verbessern.</p> <p> </p> <p>Die Leistung von EMD bestimmt direkt die Entladekapazität, die Betriebsspannung, die kontinuierliche Entladefähigkeit und die Lebensdauer einer Batterie. Seine hohe Reinheit minimiert Nebenreaktionen innerhalb der Batterie und verbessert dadurch die Lagerstabilität. Darüber hinaus erleichtern seine einzigartige Porenstruktur und die große spezifische Oberfläche das Eindringen des Elektrolyten und die Ionenmigration und sorgen so für eine hervorragende elektrochemische Leistung.</p> <p> </p> <p>Daher ist die Entwicklung der EMD-Industrie eng mit der Marktnachfrage nach Primärbatterien, insbesondere Alkalibatterien, verknüpft, was sie zu einem wesentlichen „industriellen Grundpfeiler“ für unzählige elektronische Endprodukte macht.</p> <div style="text-align:center"><img alt="" src="/upload/66/d690d8d320a73dece5de0adb2bdb10.png.webp"></div>
