Zn-added lithium ion battery cathode material and preparation method thereof

Abstract

The invention discloses a Zn-added lithium ion battery cathode material and a preparation method thereof. The cathode material is prepared by using FeC2O4.2H2O, Li2CO3, NP4H2PO4 and Zn as raw materials. The preparation method includes: mixing the raw materials according to a certain proportion; putting a mixture together with a proper amount of sucrose and steel balls into a ball milling tank for ball milling under dispersing protection of acetone; air-drying powder after ball milling, performing vacuum sealing, placing at high temperature for calcining, and obtaining the Zn-added lithium ion battery cathode material after calcining reaction. The preparation method is simple in condition control and easy in industrialization.

Description

technical field

[0001] The invention relates to a lithium ion battery cathode material and a preparation method thereof, in particular to a battery cathode material added with Zn element, which belongs to the field of batteries. Background technique

[0002] As the global energy issue becomes increasingly tense, the search for clean, environmentally friendly, and non-polluting renewable materials has become the focus of chemical power sources. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li+MnO 2 =LiMnO 2， This reaction is a redox reaction. Lithium-ion batteries are widely used in portable appliances and new vehicles due to their advantages such as high specific energy, high working voltage, long cycle life, no memory effect, and no pollution.
