Abstract: This application provides a positive electrode active material. Surface of a first lithium salt is coated with a coating layer containing a second lithium salt, which not only blocks the corrosive decomposition of the first lithium salt by the electrolyte but also allows the second lithium salt to form CEI films in situ on surfaces of the first lithium salt particles, thereby improving the film structure and avoiding the decomposition of active components in the electrolyte. Additionally, the second lithium salt contains both elements fluorine and phosphorus, which makes the composition of the film formed as consistent as possible with the composition of the film formed by lithium hexafluorophosphate in the electrolyte, thereby reducing the consumption of active lithium in the electrolyte. The positive electrode active material of this application can significantly improve the power performance and cycle life of batteries.
