Method for producing electrode material with ferrophosphorus

Abstract

The invention relates to a method for applying ferro phosphorus to manufacture electrode material with low cost, belonging to a material and electrochemical field. The ferro phosphorus at least comprises P and Fe elements at the same time, thus providing part or all sources of phosphorus and ferro for the electrode material; the ferro phosphorus can be mineral, the smelt products thereof, byproducts of phosphorus chemical industry or silicate chemical industry, or self-made. Compared with the prior art, the method has rich source, low cost, simple manufacture method and process, short production flow; the impurity elements inside the material can be used for carrying out in-situ self-doping modification the invention can effectively increase cycling efficiency and utilization rate of resources, and reduce electrode material cost from the source; the invention is practical and easy for large-scale industrial clean production to realize consumption reduction, energy conservation and comprehensive utilization of resources.

Description

technical field The invention relates to a method for preparing electrode materials from ferrophosphorus, especially a method for low-cost electrode materials, and belongs to the field of materials and electrochemistry. Background technique With the rapid development of economy and society, people are increasingly dependent on energy, while traditional fossil fuels are increasingly depleted and people's awareness of environmental protection is gradually increasing. Environmentally friendly green new energy storage and conversion devices and devices have attracted attention from all over the world. A great deal of manpower and material resources have been invested in research, and new energy sources represented by electric vehicles, power tools and large energy storage devices are competing to be developed. At present, electrode materials are a key bottleneck hindering the rapid development of this type of energy, and the price of materials is undoubtedly a fatal factor restr...
