Wang, Zhiqun published the artcileCerium triflate as superoxide radical scavenger to improve cycle life of Li-O2 battery, Synthetic Route of 143-24-8, the main research area is cerium triflate superoxide radical scavenger lithium oxide battery.
Cerium triflate (Ce(CF3SO3)3) is used as a superoxide radical scavenger in the ether-based liquid electrolyte for the Li-O2 batteries. The radical scavenging capability of Ce3+ is evaluated both in potassium superoxide + crown solution and the Li-O2 batteries. The chem. analyses further demonstrate cerium ions can effectively slow down the decomposition of electrolyte attacked by superoxide radicals. When the capacity is fixed to 1000 mAh g-1 at a c.d. of 500 mA g-1, the Li-O2 battery with 1M LiTFSI-TEGDME electrolyte begins to drop its discharge voltage rapidly to 2.0 V near 40th cycle while the electrolyte with Ce3+ additives is still above 2.0 V after 88 cycles, demonstrating the cycle life of the Li-O2 batteries show remarkably improved compared to the Li-O2 batteries without any additive into electrolyte.
