The power capability of the NASICON‐type Li 3 V 2 (PO 4 ) 3 electrode is greatly improved by coating with PEDOT , that is, poly(3,4‐ethylenedioxythiophene), a conducting polymer. The Li 3 V 2 (PO 4 ) 3 /PEDOT electrode delivers more than 90% of its theoretical capacity (133 mAh g −1 ) at a 10 C rate and 97% of this capacity is retained at this rate after 100 cycles. This remarkable power and cycle stability achieved by a simple coating process makes this 4 V‐class electrode one of the most promising electrode candidates for next‐generation batteries.
