Description
Summary:NH4V4O10 based ammonium vanadium bronze has been widely investigated as a cathode material for lithium-ion batteries. A V4O10 group based H6V4O10 might be a potential anode material due to its high hydrogen content and similar composition. Microspheres modified by loosely distributed nanoparticles showed higher discharge capacity and better cycling stability than those composed of tightly packed micro-blocks for lithium-ion batteries and zinc-ion batteries. The former can steadily cycle at current densities of 400 mA g-1 for 1000 cycles with a capacity of up to 387 mA h g-1. The discharge capacity of aqueous zinc-ion batteries can be up to 238.8 mA h g-1 with a capacity retention of 87.8% after 26 cycles. The improved electrochemical performance can be ascribed to the nanoparticles modifying the loose surface, which promotes ion and electron transfer.
