| titleOfInvention | Nitrogen-doped mesoporous hollow carbon microsphere lithium-sulfur battery positive electrode material and preparation method thereof |
| abstract | The invention relates to the technical field of lithium-sulfur batteries and discloses a positive electrode material of a lithium-sulfur battery with nitrogen-doped mesoporous hollow carbon microspheres, plays a role in buffering stress on the volume expansion of the elemental sulfur, relieves the volume change of the elemental sulfur, maintains the structural stability and the circulation stability of the anode material, simultaneously has unique hollow and mesoporous structures of the nitrogen-doped mesoporous hollow carbon microsphere, has strong physical space confinement effect on polysulfide, can reduce polysulfide from dissolving into electrolyte, effectively reduces shuttle effect, avoids the loss of sulfur active substances and the rapid attenuation of capacity, and graphite nitrogen and other structures generated by nitrogen doping are beneficial to adjusting the conductivity and electrochemical properties of the porous carbon, and the transmission and migration of electrons are promoted, so that the conductivity and rate capability of the anode material are improved. |
