Reduced graphene oxide separator improves performance of Li-sulfur battery
31 May 2015
Researchers in have shown that a lithium-sulfur (Li-S) battery with a reduced graphen oxide (rGO) -coated separator exhibits much smaller impedance and much better electrochemical performance than cells with an uncoated separator. After coating with rGO, the initial discharge capacity can be as large as 1067 mAh g−1 at 0.2... Read more →
