| titleOfInvention | A kind of preparation method of lithium-sulfur cell sulphur/carbon anode composite material |
| abstract | The invention provides a kind of preparation method of lithium-sulfur cell sulphur/carbon anode composite material, comprise the following steps：（1）Prepare pre-reaction solution a；（2）A certain amount of Dopamine hydrochloride is added in pre-reaction solution a, then carries out ultrasound polymerization reaction, reaction is filtered after terminating, and obtains the presoma b of solid state；（3）Presoma b is first warming up to 400 DEG C, high temperature sintering 3h under an ar atmosphere, is then warming up to 850 DEG C, high temperature sintering 3h again, obtains carrying sulphur carbon matrix material c；（4）Sulphur carbon matrix material c will be carried to mix by a certain percentage with elemental sulfur, after grinding uniformly in inert gas atmosphere under air-tight state, 155 DEG C of insulation 12h of high temperature, 300 DEG C of insulation 2h are then heated to, obtain sulphur/carbon composite d.It is an advantage of the invention that improving the electric conductivity of elemental sulfur, optimize the specific surface area of carbon skeleton, be load and the expansion slot milling of active elemental sulphur, while stop that polysulfide dissolves into electrolyte, improve the electrical property of sulfur electrode. |
