| 제목 | Enhanced performance of Sulfur Nanowire array for Lithium Sulfur battery |
| 초록 | Alternative rechargeable battery systems whose energy densities can go beyond those of LIBs have been extensively pursued.Elemental sulfur is a promising cathode material for a number of desirable properties. Sulfur cathodes have a theoretical specific capacity of 1675 mAh g-1. Moreover, using sulfur as the cathode material for batteries has many other advantages such as low cost, abundant, environmental benignity and widespread availability Despite the considerable promises, a number of significant challenges need to be solved for the commercialization; intrinsic poor electrical conductivity of sulfur, dissolution of high-order polysulfides in electrolyte and large volumetric expansion of sulfur. In the present investigation, we developed a sulfur electrode focusing on electrode design. In the electrode design perspective, sulfur was completely covered by minimal amount of carbon, and the carbon coated sulfur nanowire was highly aligned. The electrode design address all of the aforementioned issues at once and result in excellent electrical performance |
