The invention relates to the technical field of nursery stocks, in particular to a lithium ion battery cathode material lithium ferric manganese phosphate material and preparation processing equipment thereof.The lithium ion battery cathode material lithium ferric manganese phosphate material is prepared from 70-100 parts of lithium iron phosphate, 5-10 parts of conductive material, 5-10 parts of binder, 5-10 parts of modified silver powder, 25-50 parts of deionized water, 1-3 parts of metal oxide, 2-5 parts of dispersing agent and 1-3 parts of low-temperature resistance material; the conductive material comprises a carbon conductive agent and a metal ion conductive agent, the ratio of the carbon conductive agent to the metal ion conductive agent is 1: 1, and the carbon conductive agent comprises one or more of carbon black, amorphous carbon, carbon nanotubes, carbon nanowires, carbon gel and graphene. The lithium iron phosphate battery has the beneficial effects that when the battery is used in a low-temperature environment, the resistance value of the low-temperature resistance material is increased due to temperature reduction, so that the calorific value of the lithium battery is increased, the lithium ion battery can be normally conductive due to temperature rise, and the lithium iron phosphate battery can continue to work.
