Abstract

La présente invention concerne un procédé de préparation de phosphate de fer de sodium de matériau d'électrode positive de batterie au lithium-ion poreux, comprenant le mélange de nitrate ferreux, de nitrate d'argent et d'un agent réducteur pour préparer une solution mixte ; l'ajout goutte à goutte de la solution mixte dans une solution de carbonate pour une réaction afin d'obtenir un précipité ; le mélange du précipité avec du dihydrogénophosphate de sodium et de l'iodure de sodium, puis le broyage dudit mélange obtenu ; et le frittage du matériau broyé dans l'état d'isolation à l'air, et le trempage du matériau fritté dans un solvant organique pour obtenir le phosphate de fer de sodium de matériau d'électrode positive de batterie au lithium-ion poreux. Selon la présente invention, un mélange de carbonate d'argent et de carbonate ferreux est préparé au moyen d'un procédé de co-précipitation ; un eutectique dopé à l'échelle atomique argent-fer est obtenu et est ensuite co-fritté avec du dihydrogénophosphate de sodium et de l'iodure de sodium pour préparer du phosphate de fer de sodium ; lorsque du dihydrogénophosphate de sodium et du carbonate ferreux sont soumis à un mélange et frittage en phase solide, du carbonate d'argent est décomposé en dioxyde de carbone et en oxyde d'argent, et de l'oxyde d'argent est ensuite décomposé en une substance simple d'argent et de l'oxygène ; et la substance simple d'argent est capable d'améliorer la conductivité d'un matériau, et ne laisse pas de risques de sécurité potentiels pour une batterie comme d'autres matières étrangères magnétiques et les impuretés.
