The article was written by Wang, Junjie; Qu, Subing; Zhang, Runyu; Yang, Ke; Zhang, Shiyan; Nuzzo, Ralph G.; Nanda, Jagjit; Braun, Paul V.. The article contains the following contents:
3D-structured Se-loaded bicontinuous porous carbon (BPC) electrodes are fabricated through colloidal templating of BPC followed by pulsed-voltage Se electrodeposition. The resultant electrodes are found to deliver a specific capacity of 665 mAh g-1 at a rate of 0.1 C, near the theor. value for Se. When a vinylene carbonate (VC) containing electrolyte is utilized, the capacity fade over 500 cycles at 1 C rate is as small as a few percent. Impedance measurements and phys. characterization of cycled electrodes indicate the exceptionally stable cycling performance is possibly due to VC resulting in the formation of a stable solid electrolyte interface (SEI) during cycling. Along with the cycling stability, the rate performance of the 3D Se/BPC electrodes is also good. Due to the bicontinuous structure of carbonaceous current collector at rates as high as 5 C, the deliverable capacity is about 300 mAh g-1. In the experiment, the researchers used Vinylene carbonate(cas: 872-36-6Recommanded Product: 872-36-6)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Recommanded Product: 872-36-6
