Background
In recent years, environmental problems are increasingly raised due to carbon emissions from fossil energy consumption, and the development of renewable energy sources such as solar energy, wind energy, tidal energy and the like on a large scale has become a global important consensus for advancing energy consumption structures toward low carbonization and cleaning. Since the commercialization of SONY in the 90 th century, lithium ion batteries have been widely used in the fields of mobile electronic devices, electric vehicles, and the like. With the increasingly wide application of lithium ion batteries, lithium resources with insufficient reserves in the crust will not meet the increasing huge demand, so the development of other battery technologies capable of effectively replacing lithium ion batteries in the energy storage field is urgent. Sodium and potassium resources are very abundant and distributed uniformly, and sodium, potassium and lithium are the same main group elements and have similar chemical properties, so that the development of sodium ion and potassium ion batteries can be used for referencing the successful experience of lithium ion batteries.
The most promising materials for large scale negative electrodes for sodium and potassium ion batteries are hard carbon materials. The microstructure of the hard carbon is short-range ordered micro-regions stacked by curved graphite-like sheets, and the random stacking of each micro-region leaves more nano holes. Because it tends to have a larger interlayer spacing (typically greater than 0.37 nm), more nanopores, and more defect sites, more sodium or potassium ions can be stored, with higher specific capacity. The performance of the hard carbon material on sodium ion or potassium ion batteries is still in the development stage, and physicochemical indexes such as granularity, specific surface, ash content and interlayer spacing are also limiting the capacity and first effect of the hard carbon material. Therefore, there is a need to propose a new solution to the above-mentioned problems.
