| 英文摘要 | Lithium-sulfur batteries with potentially high specific energy are viewed as very promising candidates for next-generation lightweight and low-cost rechargeable batteries. However, sulfur-based cathodes suffer from dissolution of polysulfides causing shuttle effects. Here, in order to confine elemental sulfur and anchor the polysulfides, a novel host that is an inexpensive natural clay mineral, viz., vermiculite is proposed. When compared to regular carbon-sulfur composites, vermiculite-sulfur composites offer promising rate capability and much better cycling stabilities, displaying capacity retentions of approximate to 89 and approximate to 93% within 200 cycles at C/2 and 1 C, respectively, and approximate to 60 % at C/5 within 1000 cycles. Postmortem studies, advanced adsorption tests, density functional theory calculations, and zeta potential measurements in combination with intrinsic characteristics of the natural vermiculite provide insights into the new mechanism. The vermiculite contains naturally present surface cations which show a strong tendency to adsorb S-n(2-) anions, hence protecting them from dissolution. The excess surface charge is most probably compensated by excess Li+ in the space charge zones which is beneficial for charge transfer and local conductivity. The reported results show that natural clay-minerals are promising sulfur hosts being able to fixate sulfides via electrical double layer effects, thus enabling high-performance in lithium-chalcogen batteries. |
