Vanadium oxide coated with conductive polymers for zinc-ion battery cathode

Rechargeable aqueous zinc ion batteries (RAZBs) have been used extensively because of their safety and low-cost. As an available cathode material for ZIBs, layered vanadium oxide (V2O5) has been considered due to its high specific discharge capacity. Because V2O5 is slightly soluble in water, it is suitable for modifying V2O5 with conductive polymers to stabilize […]

Gelatin modified separator for dendrite free metal anode

In commercial batteries, metal anode-based batteries, mainly using zinc or lithium as the anode, provide higher battery capacity than traditional metal ion batteries. Lithium metal anodes have a theoretical specific capacity 10 times higher than commercial lithium ion batteries with graphite as the anode. Zinc anodes are excellent anodes for use in aqueous batteries, because […]
