Using Li metal-free anodes for Li-ion oxygen and Li-ion S batteries is considered as a promising solution to resolve the hazard of Li metal anode. Although Si anode exhibits high capacity and low electrochem. potential, it cannot match with O (or S) cathode, because both lack cycleable Li ions. Here, a free-standing and fibrous Si/C anode is prepared by electrospinning and its simple but effective lithiation is proposed. When assembling the cells, the free-standing Si/C anode was put between mass-controlled lithium metal foil and separator, and then the Si/C anode could be lithiated after adding electrolytes. By optimizing a LiFSI based ether electrolyte, the Si/C anode could achieve good cycleablity comparable to that in carbonate electrolytes. The lithiated Si-O cells exhibit better cycling stability than the Li-O cells with gel polymer electrolyte. Because both Si anode and S@pPAN cathode are compatible with carbonate electrolytes, exceptional cycling performance has been achieved for the lithiated Si-S cells. This simple method could pave the way to com. applications of Li-ion O and Li-ion S batteries.
