Abstract
The invention provides an oligomer macromolecule and a lithium battery. The oligomer macromolecule is obtained by reaction of epoxy acrylate with barbituric acid. The lithium battery includes an anode, a cathode, an isolation film, an electrolyte solution and a packaging structure, wherein the cathode comprises the oligomer macromolecule. The oligomer macromolecule provided by the invention can beapplied to the cathode material of the lithium battery, so that the lithium battery has good performance and safety.
Description
technical field [0001] The invention relates to an oligomer polymer and a lithium battery, and in particular to an oligomer polymer and a lithium battery used for a lithium battery. Background technique [0002] Since the primary battery does not meet the requirements of environmental protection, the market demand for secondary lithium batteries that can be repeatedly charged and discharged with the characteristics of light weight, high voltage value and high energy density is increasing day by day in recent years. Therefore, the performance requirements for secondary lithium batteries such as light weight and durability, high voltage, high energy density and high safety are becoming higher and higher. The application and expansion potential of secondary lithium batteries, especially in light electric vehicles, electric vehicles, and large-scale power storage industries, is quite high. [0003] However, in general commercialized secondary lithium batteries on the market, du...
