Temperature Dependence of Hard Carbon Performance in Sodium Half-Cells with 1 M NaClO4 in EC/DEC Electrolyte

نویسندگان

چکیده

In recent years, sodium-ion batteries (SIBs) have attracted much attention as an alternative to lithium-ion batteries. Hard carbon (HC) is a well-studied anode material for SIBs; however, the performance function of temperature less established. To investigate dependence HC, sodium half-cells with common NaClO4-based electrolyte were tested at temperatures from 10 80 °C. Capacity after 20 cycles 100 mA g−1 current varied 90 h °C 270 60 Increased significantly improves HC rate capability, 120 capacity found 500 current. Stability was high moderate 220 remaining 200 40 g−1.

Supercapacitive Performance of Ordered Mesoporous Carbon (CMK-3) in Neutral Aqueous Electrolyte

Ordered Mesoporous Carbon (OMC) represents an interesting material for electric double layer capacitors which has the high surface area, easily accessed ordered pore channels and lower production cost. In this work, CMK-3 as promising OMC has been fabricated using the ordered mesoporous silica SBA-15 as a template. The structure and morphology of CMK-3 are characterized by X-ray diffraction...
