Description
Technical Field
The invention relates to a method for improving the sintering relative density of a lithium lanthanum zirconium oxygen ceramic wafer, which is applied to the field of manufacturing of all-solid-state lithium ion batteries.
Background
The lithium ion battery has the advantages of high energy density, wide working temperature range, environmental friendliness, large output power, low self-discharge and the like, and is widely applied to the fields of electric automobiles, energy storage equipment, electronic equipment and the like. However, the traditional lithium ion battery contains organic electrolyte which has the characteristics of flammability and easy explosion. If the organic electrolyte leaks under the action of external force, faults such as short circuit and the like are easily caused, and accidents such as combustion, explosion and the like of the battery can be caused in serious cases.
The solid electrolyte is used as a substitute for organic electrolyte, and has the advantages of good chemical stability, long cycle life, high energy density, good mechanical property, stability for lithium metal cathode, simple preparation and assembly and the like. The solid electrolyte comprises an inorganic solid electrolyte, an organic solid electrolyte and a composite electrolyte. Wherein the inorganic solid electrolyte effects the transfer of charge primarily through the movement of lithium ions.
The cubic-phase lithium lanthanum zirconium oxide is a material which is researched more in inorganic solid electrolyte and has the advantages of high lithium ion conductivity, good chemical stability, wide electrochemical window and the like. However, the solid-phase sintering method for preparing the lithium lanthanum zirconium oxide ceramic wafer needs to be sintered in an environment with the temperature of more than 1000 ℃. At high temperature, lithium in lithium lanthanum zirconium oxide is easily converted into lithium vapor, and the lithium vapor is easily volatilized or reacts with oxygen in air, so that pores appear in the material and lithium loss is caused. In the invention, powder with the same components is added on the upper side and the lower side of the lithium lanthanum zirconium oxide ceramic plate in the sintering process, and gas which does not react with lithium is introduced, thereby supplementing the lithium lost by volatilization, reducing the lithium consumed by side reaction and improving the relative density of the sintered lithium lanthanum zirconium oxide ceramic plate.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a method for improving the sintering relative density of a lithium lanthanum zirconium oxygen ceramic wafer.
The purpose of the invention is realized by the following scheme: the method for improving the relative density of the sintered lithium lanthanum zirconium oxide ceramic wafer comprises the following steps of adding powder with the same components to the upper side and the lower side of the lithium lanthanum zirconium oxide ceramic wafer during sintering, and introducing gas to improve the relative density of the sintered lithium lanthanum zirconium oxide ceramic wafer:
(1) taking a proper amount of lithium lanthanum zirconium oxygen powder, and prepressing for 3-10min under the pressure of 30-45MPa to form a wafer to obtain a lithium lanthanum zirconium oxygen prepressurizing sheet;
(2) taking a proper amount of lithium lanthanum zirconium oxygen powder, placing the lithium lanthanum zirconium oxygen pre-pressing sheet in a crucible, and adding the lithium lanthanum zirconium oxygen powder again to cover the pre-pressing sheet;
(3) placing the crucible in the step (2) in a tubular furnace and introducing gas;
(4) adjusting the temperature of the tube furnace, sintering at 1100-1250 ℃ for 2-8 hours, and cooling along with the furnace to obtain the lithium lanthanum zirconium oxygen ceramic wafer.
On the basis of the scheme, in the step (2), the crucible used can be one of an alumina crucible and a platinum crucible.
On the basis of the scheme, in the step (3), the introduced gas can be one or a mixture of helium, neon and argon.
The invention finds a method for improving the sintering relative density of a lithium lanthanum zirconium oxygen ceramic wafer, which supplements lithium lost due to high-temperature gasification in the sintering process by adding lithium lanthanum zirconium oxygen powder with the same components at the lower two sides of a lithium lanthanum zirconium oxygen pre-pressing wafer and introducing gas which does not react with lithium in the sintering process, and simultaneously eliminates the influence of oxygen in air and prevents a second phase formed by insufficient lithium in a product due to the reaction of the lithium and the oxygen. The lithium lanthanum zirconium oxygen ceramic wafer prepared by the method has higher relative density, less defects such as air holes, microcracks and the like in the material, and the material phase is a pure cubic phase and has better ion conductivity.
The invention has the advantages that: a new method for sintering the LLZO ceramic chip is found, so that the relative density of the sintered LLZO ceramic chip is greatly improved, the relative density of the sintered and molded LLZO ceramic chip is more than 95%, the defects of air holes, microcracks and the like in the finished LLZO ceramic chip are fewer, the grain size is uniform and tightly combined, and the LLZO ceramic chip has excellent ionic conductivity and better mechanical properties.
