DOPED CARBON-SULFUR SPECIES NANOCOMPOSITE CATHODE FOR LI-S BATTERIES |
摘要 |
We report a heteroatom-doped carbon framework that acts both as conductive network and polysulfide immobilizer for lithium-sulfur cathodes. The doped carbon forms chemical bonding with elemental sulfur and/or sulfur compound. This can significantly inhibit the diffusion of lithium polysulfides in the electrolyte, leading to high capacity retention and high coulombic efficiency. |
