摘要：

We constructed rechargeable Na-SO2 batteries, based on a NaI redox mediator and containing a gel-polymer electrolyte and a multiwall carbon nanotube@Ni foam porous cathode, with a newly demonstrated battery reaction, specifically 2Na + 2SO(2) <-> Na2S2O4. A large reversible capacity of 5000 mA h g(-1) at 200 mA g(-1) (763 W h kg(-1)) and a high capacity retention of nearly 100% after 100 cycles were obtained.
