Description

Electrolyte additive for improving electrochemical performance of lithium air battery
Technical Field
The invention belongs to the technical field of lithium air batteries, and particularly relates to an electrolyte additive for improving the electrochemical performance of a lithium air battery.
Background
In the past decades, lithium ion batteries have been rapidly developed, have been widely used as main power sources for portable electronic devices such as mobile phones and notebook computers, and have become necessities for human life. However, with the development of high-specific energy devices such as electric vehicles and power grid energy storage, the energy density of the conventional lithium ion battery system operating by the "insertion-extraction" mechanism has been difficult to meet the current market demand. Therefore, the development of new high specific energy storage systems is urgently needed. The lithium-air battery directly adopts metal lithium with the highest theoretical specific capacity (3860mAh/g) and the most negative electrode potential (-3.04V vs. Standard Hydrogen Electrode (SHE)) as a negative electrode and oxygen in the air continuously as an active material of a positive electrode, has the theoretical energy density of about 11680Wh/kg without considering the oxygen quality, can be comparable with gasoline, and is considered as a next-generation high-specific-energy storage system with the most development prospect. However, the complicated reaction history and the delayed multiphase reaction kinetics lead to serious polarization in the charge and discharge process, which causes many problems of low energy efficiency, poor rate capability and cycle performance, and the like, and restricts the commercial application process. Catalysis is key to improving reaction kinetics, and therefore, the design and development of oxygen electrode catalysts are the core problems and research focus of lithium-air batteries.
In order to reduce the charging and discharging overpotential of the lithium air battery, researchers invest a great deal of energy in the aspect of solid-phase oxygen electrode surface catalysis, and develop various solid-phase oxygen electrode catalysts such as carbon materials, noble metals, non-noble metals, composite materials and the like through a series of material design and synthesis methods, and the catalysts effectively improve the reaction kinetics of the lithium air battery, so that the performance of the battery is obviously improved. However, although the solid-phase oxygen electrode catalyst can reduce the charge and discharge overpotential of the lithium air battery to some extent, it has some inherent disadvantages in itself. E.g. with the discharge product Li2O2The solid/solid contact sites between the two are very limited, which limits the catalytic efficiency of the catalyst on one hand and easily causes Li on the other hand2O2Interfacial separation occurs during decomposition, leading to Li2O2The decomposition is incomplete. In order to solve these problems, in recent years, researchers have proposed using a liquid phase additive (also called redox mediator) instead of a solid phase catalyst to reduce the overpotential during charge and discharge. The redox media, such as lithium iodide, tetrathiafulvalene, TEMPO and the like, can be dissolved in the electrolyte, so that the catalyst and Li are greatly increased2O2The contact area of (a). During charging, the redox mediator is first oxidized to the oxidized state and then oxidized to decompose Li2O2And then restores itself to a reduced state. However, the redox mediators reported at present still have some problems, such as that the overpotential during the charge and discharge process is still large, the cycle stability is poor, and the oxidation state of the redox mediator is easy to shuttle to the negative electrode side to react with the lithium metal, so that the lithium metal negative electrode is corroded.
