Problems solved by technology

In recent years, many experts and companies are also exploring new renewable energy sources to replace these non-renewable resources, such as solar energy and wind energy, and have made some progress. However, the output of these energy sources is unstable and time-sensitive. Therefore, some energy storage devices are needed to store the energy, and then through these devices to achieve stable energy output

Description

technical field [0001] The invention relates to the field of materials, in particular to a capacitor element composite material and a preparation method thereof. Background technique [0002] With the rapid development of the world economy and the rapid growth of population, environmental pollution and energy shortages have become worldwide problems to be solved urgently. Especially with the depletion of non-renewable resources such as oil, and the further expansion of energy demand today, the problem of energy shortage is directly related to economic development and social stability. In recent years, many experts and companies are also exploring new renewable energy sources to replace these non-renewable resources, such as solar energy and wind energy, and have made some progress. However, the output of these energy sources is unstable and time-sensitive. Therefore, some energy storage devices are needed to store the energy, and then realize the stable output of energy thr...
