Composite graphite felt (GF) electrodes modified by using a carbon network are fabricated for vanadium redox flow batteries (VRFBs). The electrodes are derived through the in situ polymerization of p‐phenylenediamine and phytic acid on GF fibers, followed by high‐temperature calcinations performed in an inert atmosphere. The composite electrodes exhibited higher electrocatalytic activities for the VO2+/VO2+ and V2+/V3+ redox species compared with the original GF electrode. The peak potential was reduced by 357 mV, which could be attributed to the increased number of active sites and diffusion pathways; the energy efficiency of the composite electrode increased by 6 % (current density: 200 mA cm−2). Based on the above‐mentioned structural design, a battery containing the composite electrodes exhibited excellent cycling stability without any obvious efficiency decay after 1000 cycles, indicating its applicability for large‐scale VRFBs.

Mesophase microporous carbon spheres (MMCS), are the anode materials of spent lithium-ion batteries (LIB), existing in large amounts on the earth that result in resource wastes and ecological pollution. In order to utilize the above waste resources, a new idea of recycling scrapped LIB anode materials was exploited to apply for capacitive deionization (CDI). Herein, the activated microporous carbon spheres (AMCS) were synthesized by a one-step KOH activation of mesophase microporous carbon spheres (MMCS). By controlling the weight ratios of KOH to MMCS, the fabricated AMCS with the optimal specific surface area of 2626 m 2 g À 1 and the pore volume of 0.98 cm 3 g À 1 were fabricated. The AMCS3-1 with a weight ratio of KOH to MMCS of 3 : 1 exhibits higher specific capacitance (196.9 F g À 1) and lower charge transfer resistance. Importantly, the AMCS3-1 electrode demonstrates excellent electrosorption capacity of 12.73 mg g À 1 and fast salt adsorption rate of 2.64 mg g À 1 min À 1 at 1.2 V. In addition, the excellent repeatability over 50 regeneration cycles could be obtained for AMCS3-1 electrode compared with commercial activated carbon electrode. The results reveal that the AMCS3-1 is a promising candidate as high-performance electrodes for CDI. The strategy of recycling MMCS from waste LIB anode materials for CDI is desirable, which displays great potential in the removal of sodium chloride (NaCl).
