Conductive graphite fiber as a stable host for zinc metal anodes

Challenges, mitigation strategies and perspectives in development of zinc-electrode materials and fabrication for rechargeable zinc–air batteries

“…Activated carbon could provide the room for Zn dendrites and other passivation products due to the rich and well-developed pores, ensuring the activity of zinc particles. Similarly, Wang et al 98 employed highly conductive carbon fiber-graphite felt (GF) as an electronic collector to prepare a self-supported Zn@GF negative electrode ( Fig. 9c and d) and a high battery performance was achieved by using such an electrode in 0.5 M Na 2 SO 4 and 0.05 M ZnSO 4 ( Fig.…”

“…9e-g). 98 Besides adding carbon-based materials, the incorporation of ZnO with a porous zinc-electrode is also considered to be an alternative solution to control the volume change of the zinc-electrode by compensating for the dissolved zinc active material during discharge/charge cycles. 99,101,103,135 With the aim of alleviating zinc-electrode corrosion, metal and metal oxide/hydroxide can be added into the electrode as inorganic corrosion inhibitors.…”

3D zinc@carbon fiber composite framework anode for aqueous Zn–MnO2 batteries

“…The Zn@CFs core-shell structure provides zinc anode with larger electrochemical reaction area 28 and can withstand the inside strain and stress during Zn plating or stripping process. By combining this 3D dendrite-free Zn anode with the a-MnO 2 nanober cathode, an aqueous full cell ( Fig.…”
