Fig. 1 a) Typical 3 rd  charge/discharge cycle (at C/5, 26 mA.g -1 ) obtained for K//KVPF- K//KVPF-C cells indicating at which potentials cells were stopped for the analysis of the redox  processes involved in KVPF-C
Fig. 2. Vanadium mean oxidation state (DO) of KVPO 4 F 0.9 -O 0.1 -C, as the K content  changed during the 3 rd  cycle, determined from the charge/discharge capacity on one side  and from the analysis of the XPS spectra on the other side
Fig. 3  Capacity (mAh.g -1 ) related to the 1 st , 2 nd , 3 rd  and 4 th  redox processes as obtained from  the derivative of the galvanostatic charge/discharge curves
