Problems solved by technology

The resulting negative problem is that sub-micron materials have strong water absorption. After moisture is brought into the lithium battery, it will chemically react with the lithium salt in the electrolyte, destroying the ion conductivity of the lithium salt and forming HF, which leads to battery life. more severe structural damage
[0006] 3. The power lithium battery needs to guarantee the durability of more than 10 years, so it is required to maintain good and long-lasting adhesion between the ceramic particles and the binder. -Obvious failure occurs after 500 times, which cannot meet the basic needs of power lithium batteries

Abstract

The invention provides organic metal complex.The organic metal complex is prepared by mixing bis(2-methyl-8-oxyquinoline-N1, O8)-(1, 1'-biphenyl-4-hydroxyl)aluminum and 8-oxychinolin aluminum, wherein the weight ratio of the bis(2-methyl-8-oxyquinoline-N1, O8)-(1, 1'-biphenyl-4-hydroxyl)aluminum and 8-oxychinolin aluminum to the 8-oxychinolin aluminum is 2-5:5-8.Atmosphere generated during high-temperature decomposition can have embedding and co-growth of certain degree, so that the growth orientation of crystals can be changed, the atomic structure on the surface of microcosmic particles can be improved, and functional material crystal structure design is achieved.When aluminum oxide compound obtained from the organic metal complex is prepared into a coating membrane, the coating membrane is outstanding in water absorption performance, and the self-discharge performance, voltage drop performance and normal-temperature circulation performance of the coating membrane are evidently better than those of a common aluminum oxide coating membrane.The preparation method of the organic metal complex is simple, practical, evident in effect, and capable of satisfying the requirements of large-scale industrial production.

Description

technical field [0001] The invention relates to the field of power lithium battery manufacturing, in particular to a preparation method and product of an organometallic complex and an alumina compound. Background technique [0002] With the urgent requirements of the development of new energy technology, lithium-ion power batteries have become the first choice for new energy technology due to their high specific energy density, no memory effect and relative environmental protection, but ordinary lithium-ion power batteries also have certain safety Hidden dangers are mainly manifested in the case of thermal failure, external shock and drop, and the battery may catch fire or explode due to diaphragm damage and other reasons. In recent years, the global safety improvement methods for lithium batteries, especially power lithium batteries, are mainly through ceramics, which are also methods such as alfa phase alumina coating to improve the material deformation effect of the diaph...
