AI Technical Summary
Existing methods for disposing of spent zinc ion capacitor carbon involve resource waste and potential pollution risks, and are difficult to meet the performance requirements of energy storage electrodes. Traditional regeneration technologies are complex and have a high risk of secondary pollution.
A device comprising a separation system, a mixing system, a sintering system, and a post-processing system is used to prepare hard carbon materials by high-temperature sintering. Using spent zinc ion capacitive carbon as a precursor, and combined with a regenerative heat exchanger, energy is utilized in a cascade manner, avoiding the use of chemical reagents, and achieving green disposal and high-value utilization of zinc ion capacitive carbon.
This method enables the efficient conversion of depleted zinc ion capacitor carbon into hard carbon materials, reducing preparation costs, improving material performance, reducing environmental pollution, and achieving both environmental and economic benefits, while also broadening the sources of hard carbon raw materials.
