| titleOfInvention | A kind of phosphate-modified diaphragm of lithium-sulfur cell and its preparation, coating method |
| abstract | The present invention discloses phosphate-modified diaphragm and its preparation, coating method of a kind of lithium-sulfur cell, belongs to the technical field of battery.The preparation process of the cobalt phosphate nickel carbon compound are as follows: metal inorganic salt is dissolved in deionized water, be added conductive agent, phosphoric acid or and ammonium dihydrogen phosphate, after stirring be added ammonium hydroxide or with ethanol amine adjust pH7, be stirred to react 1 ~ 5h, it filters, is washed with deionized after standing 5 ~ 20h.Filter cake is dried at 100-150 DEG C, then is put into atmosphere furnace and calcines 3 ~ 8h at 250-550 DEG C under nitrogen protection, crushes to obtain cobalt phosphate nickel carbon complex after cooling.Then, by conductive agent, binder, cobalt phosphate nickel carbon compound and deionized water solution mixed grinding, slurry is made and is coated on commercial diaphragm by positive side, dries the diaphragm and obtains phosphate-modified diaphragm.Modified diaphragm of the invention is able to suppress " the shuttle effect " of more lithium sulfides in lithium-sulfur cell, improves the chemical property, capacity and cycle life of lithium-sulfur cell, is suitable for large-scale production. |
