Abstract

The invention discloses a carbon-based chemical energy storage material and a preparation method thereof. The method comprises the step of adopting a direct physical impregnation method, an ultrasonic method or a hydrothermal method for compounding a carbon-based carrier material (Ni-CNTs composite) with an active component LiOH-H2O, thereby obtaining the carbon-based chemical energy storage material. The representation means, such as, scanning electron microscope (SEM), transmission electron microscopy (TEM), X ray diffraction analysis meter (XRD) and thermogravimetry / synchronous differential thermal analyzer (TGA-DSC), are adopted for obtaining key thermophysical parameters, such as appearance, loading components and thermal storage density, of the composite. The compounding of the nanometer carbon material can greatly promote the hydration rate of the LiOH monomer while the energy storage density is increased at various degrees. Besides, the overall heat conductivity coefficient of the material is also obviously increased due to the compounding of the nanometer carbon material.

Description

technical field [0001] The invention belongs to the technical field of preparation of energy storage materials, and in particular relates to a carbon-based chemical energy storage material and a preparation method thereof. Background technique [0002] Energy and the environment are important material foundations for human survival and social development, and important cornerstones for national economy, national security and sustainable development. With the sustained and rapid development of my country's national economy, problems such as shortage of fossil energy resources, irrational energy structure, and serious environmental pollution have become increasingly prominent. In recent years, the development of the national economy has been increasingly dependent on energy, and the contradiction between economic development and energy shortage has been deepening. In order to solve this contradiction, attention must be paid to the improvement of energy reuse rate, among which...
