Hebei Messi Biology Co., Ltd. stated that the effect of the apparent specific volume and addition amount of porous magnesium oxide on the performance of thermal batteries was systematically studied by centrifugal acceleration. The study found that the apparent specific volume of magnesium oxide had no effect on the static discharge performance at room temperature, but under the action of high temperature acceleration, when the apparent specific volume of magnesium oxide was lower than 8 mL/g, the battery safety performance was poor. The optimal mass fraction of magnesium oxide in the separator for thermal batteries is 40%, and the internal resistance is 50~100 mW. For the first time, the microstructure and surface morphology of magnesium oxide were comprehensively characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and other methods, which strongly proved the process mechanism of magnesium oxide using pore structure to absorb electrolyte, and determined the selection method of porous magnesium oxide for thermal batteries.
Thermal batteries are primary batteries whose main electrolyte is solid salt. In actual use, leakage will occur due to state changes, which will not only pollute the environment, but also cause other adverse effects. Therefore, a certain proportion of binder should be added to the electrolyte of the battery to achieve the purpose of changing the state and controlling its flow. In order to better improve the inhibitory effect on lava flow, porous magnesium oxide fibers should be added, so that the performance of the thermal battery is also improved, thus realizing the joint application of physics and chemistry to solve the problem. However, magnesium oxide still has some defects. After the adsorption material is formed, it is not only beneficial to the recycling of materials, but also can reduce the loss of materials. It can be operated on a fixed bed. Therefore, studying the adsorption and formation of magnesium oxide has important practical value.
Hebei Messi Biology Co., Ltd. stated that in nature, magnesium oxide-based adsorption materials are not only easy to obtain, but also inexpensive. The performance of this film-forming material is significantly better than that of materials in particle form. It can quickly complete adsorption in actual use and is not prone to clogging problems. This material can be used on a fixed bed because of its unique film-forming characteristics. The two molding methods compared above have simple processes, can be selected according to actual production, can effectively reduce costs, and have very good prospects and value in actual production. If it is to be applied in other fields, preliminary inspections should also be carried out to analyze whether this adsorption principle is applicable to all pollutants, so as to make a more accurate selection.
