V2O5, as a lithium-free cathode material, has inherent defects such as sluggish kinetics and volume change and, at the same time, requires a lithium metal anode that tends to form dendrites in liquid electrolytes. Both the lithium dendrite and the flammable electrolyte solvent bring longtime safety issues. This work introduces nonflammable inorganic-organic composite solid electrolyte to inhibit the growth of the lithium dendrite and suppress the instability caused by V(2)O(5)nanometerization. However, the long-term cycling and rate performances are still insufficient even when reducing V(2)O(5)size to about 50 nm. As an improvement, sub-10 nm V2O5/C nanosheets are designed and prepared using corn stalks as precursors through simple impregnation and calcination process. The V2O5/C offers a much better electrode/electrolyte contact and interface stability than bulk V(2)O(5)and commercial V(2)O(5)in the inorganic-organic composite solid electrolyte. The discharge capacity is 228 mAh g(-1)at 0.1 C after 50 cycles and approximate to 110 mAh g(-1)at 2.0 C.
