Abstract

La présente demande divulgue un agent de pré-lithiation de batterie au lithium-ion, son procédé de préparation et une application. La formule chimique de l'agent de pré-lithiation de batterie au lithium-ion est : Li<sub>5</sub>FeO<sub>4</sub>@C, et une structure de celui-ci est des particules secondaires formées par l'agglomération de particules primaires de Li<sub>5</sub>FeO<sub>4</sub>, avec un revêtement en carbone de la surface des particules primaires de Li<sub>5</sub>FeO<sub>4</sub>. Dans la présente demande, une source de carbone est mélangée avec un sel soluble de Fe, amenant des ions Fe à se fixer à la source de carbone ; après que de l'eau ammoniacale a été ajoutée, de l'hydroxyde présentant de petites particules et une bonne dispersion peut être formé, puis un oxyde à l'échelle nanométrique est obtenu au moyen d'une réaction solvothermique, et la source de carbone permet en outre d'obtenir un effet d'obstruction entre des particules dans un processus de frittage ultérieur, une croissance de particules primaires est ralentie, et de grandes particules cristallines uniques sont empêchées de croître. L'agent de pré-lithiation préparé à l'aide du présent procédé présente des particules primaires plus petites, un trajet de désintercalation de Li<sup>+</sup> plus court pendant la charge, et une bonne capacité de débit. L'agent de pré-lithiation peut fournir suffisamment de Li<sup>+</sup> lors de la charge d'une batterie pour la première fois pour amener un film de SEI à être généré sur une surface d'une électrode négative, la perte de Li<sup>+</sup> dans un matériau d'électrode positive est réduite, et l'efficacité coulombienne et la capacité d'une batterie au lithium-ion sont améliorées.
