LITHIUM SULFUR SECONDARY BATTERY |
| 摘要 |
A lithium sulfur secondary battery includes a positive electrode containing a sulfur-based positive electrode active substance, an electrolytic solution, a negative electrode containing a negative electrode active substance that occludes and releases lithium, and a polymeric film that covers a surface of the positive electrode and allows lithium cations to pass but does not allow polysulfide anions to pass. |
