An electrolyte for use in high cutoff voltage environments and its preparation method
ActiveCN121662942Bachieve releaseEfficient removalSecondary cellsChemical physicsPreferential adsorption
This invention discloses an electrolyte for use under high cutoff voltage conditions and its preparation method, relating to the field of battery electrolyte materials technology. This electrolyte, through extraction using a reference electrolyte solution, can specifically extract electrochemically active molecular components from anthocyanins, allowing them to preferentially adsorb onto the negatively charged positive electrode surface under high cutoff voltage conditions via electrostatic interactions. This not only interrupts the chain reaction but also directly anchors lattice oxygen, inhibiting lattice oxygen release at its source. It achieves a synergistic effect of a dual protection mechanism of "dynamic removal and static anchoring." Furthermore, high-speed centrifugation avoids increased ion transport impedance. This electrolyte significantly inhibits chain reactions under high cutoff voltage conditions, effectively preventing the formation of excessively thick or high-impedance interface layers, ensuring the battery's capacity and cycle capacity retention under high cutoff voltage conditions, making it suitable for large-scale application in lithium batteries under high cutoff voltage conditions.
