Description

technical field [0001] The invention relates to a preparation method of carbon materials, in particular to a magnetic energy storage composite material and its preparation method and application. Background technique [0002] Air, water, sunlight and magnetism are indispensable to human life. Human beings live in the middle of the geomagnetic field of 0.35 ~ 0.7GS, and correspondingly form their own biomagnetic field. Newborn cells are round and contain the most magnetism; old cells are triangular and contain the least magnetism, which is normal for humans. Life activities must depend on a stable magnetic field environment. Modern medicine has a deeper understanding of the role of magnetism, such as analgesic effect, anti-inflammatory effect, sedative effect, detumescence effect, effect on the blood system, effect on meridians, etc. It can be said that human health is inseparable from magnetism. [0003] Negative ions are when the atmosphere is ionized and generate a certa...
