| titleOfInvention | Lithium-sulfur secondary battery |
| abstract | The invention relates to a lithium-sulfur secondary battery comprising a positive electrode current collector, a positive electrode material, a porous diaphragm and a lithium-containing negative electrode plate as well as electrolyte, which are compressed integrally in a battery shell from bottom to top. The lithium-sulfur secondary battery is characterized in that a cellulose membrane is compressed between the positive electrode material and the porous diaphragm, and is one of a nitrocellulose membrane, a cellulose acetate membrane and a regenerated cellulose membrane. According to the invention, because the cellulose membrane is compressed between the positive electrode material and the porous diaphragm, and prevents polysulfide from transferring to a metal lithium negative electrode plate along with electrolyte in the lithium-sulfur secondary battery, inhibits side reaction caused by a 'shuttle flying phenomenon', effectively improves the coulombic efficiency of the lithium-sulfur secondary battery, prolongs the service life of the battery, and also is simple to operate, low in cost, and easy for mass production. |
