Description
Technical Field
The invention relates to a material for a positive electrode and a negative electrode of a sodium ion energy storage device, a preparation method of the material and a symmetric sodium ion energy storage device, and belongs to the field of energy storage devices.
Background
In recent years, with the development of the world economy and the increase of the environmental pressure, people have more and more urgent and strict requirements on energy, i.e. a cornerstone for social progress. The utilization of human energy from the firewood age to the coal age and then to the oil and gas age is accompanied by a great leap of productivity in every transition. However, the development and utilization of traditional fossil energy sources bring serious challenges to the sustainable development of human beings. In recent years, green development centered on reducing excessive consumption of energy resources has been vigorously developed globally, and the goal thereof is to pursue economic, social, and ecological overall coordinated sustainable development. In the process of energy conversion, human practical experience has proven a bit: the energy source can be fully and sustainably utilized by having a complete and green energy storage and discharge device system.
Energy storage devices have been developed with the replacement of the whole energy era, from the simplest direct utilization of heat energy to the conversion of mechanical energy, to the conversion of electrical energy, chemical energy, from steam engines, internal combustion engines to lead-acid batteries, to lithium batteries, solar cells, etc., energy storage devices have been developed all the time in the entanglement of the two aspects of environmental protection and energy utilization. By the new century of world development, all countries pay attention to the inevitable trend of energy transformation, and in this stage, the development of energy storage devices mainly based on lithium batteries enters a prosperous period. However, in the development process of lithium ion batteries, scientists and researchers find that the reserve of lithium and the safety of lithium batteries become bottlenecks in the overall application of lithium batteries.
In such a dilemma, when researchers reviewed the entire history of battery development again, it was discovered that in the last 80 th century, Delmas et al had confirmed Na+Can be added to the material NaxCoO2Reversibly de-intercalated. Two major problems exist with lithium ion batteries: one is resource problem, the lithium resource is not uniformly distributed in the world, and if the recovery condition is not considered, the lithium resource is estimated to be consumed in 60 years, and in addition, the cathode material of the common lithium ion battery contains rare element cobalt; secondly, safety, because the energy density of the lithium battery is very high, if a thermal runaway reaction occurs, a lot of heat can be released, and potential safety hazards exist. In view of such a situation, sodium ion batteries are at least no longer a limiting development requirement in terms of resource issues and therefore have great advantages in terms of large-scale energy storage and low-speed power batteries.
As a core component of sodium ion batteries, both positive and negative electrode materials have long been the focus of research, particularly the study of layered oxide materials. However, at present, stability still remains a main bottleneck of sodium ion positive and negative materials, and how to find a stable material which can be used for positive and negative electrodes becomes a research focus of sodium ion battery materials at present.
