Method for regulating graphite microstructure and lithium storage performance through high-current pulsed electron beam

The invention discloses a method for regulating and controlling a graphite microstructure and lithium storage performance by using a high-current pulsed electron beam. The method comprises the following steps: firstly, selecting a natural graphite or artificial graphite material; and placing the stainless steel shell filled with the natural graphite or the artificial graphite on an electron beam platform, starting equipment, starting a vacuum system, and when the vacuum degree reaches a specified value, sequentially starting a magnetic field, a spark source and cathode high voltage to enable the high-current pulse electron beam to directly irradiate the natural graphite or the artificial graphite so as to complete graphite modification. According to the invention, natural graphite or artificial graphite is modified by using a strong current pulsed electron beam, so that lithium storage active sites are increased, lithium ions are more smoothly embedded and deembedded, the rapid transfer and charge storage cap
