Batteries: Solution‐Processed All‐V2O5 Battery (Small 40/2020)

In article number 2003816, Lei Li and co-workers implement a proof-of-concept solution-processed all-V2O5 battery with symmetrical electrode structure. The electrodes are prepared via the solution-processed method, indicated by the river with the boat. V2O5 works as both cathode and anode. The storage/release charges via Li+ intercalation/de-intercalation in V2O5 like the balanced mutual transformation between “Yin” and “Yang” of the Chinese traditional “Tai Chi” diagram.
