Lithium-sulfur cell and battery |
| 摘要 |
A lithium-sulfur cell for a battery includes: a negative electrode; a positive electrode; and at least one diffusion barrier situated between the negative electrode and the positive electrode. At least one of the negative and positive electrodes includes a porous graphite foil made of expanded graphite, and the at least one diffusion barrier is composed of a brittle material having a thickness of ≧10 μm. At least two lithium-sulfur cells are provided in an interconnected arrangement in a battery. |
