Abstract:
Vanadium oxide (V2O5) is intercalated by tetrachlorobenzoquinone (TCB) through a one-step solvothermal method in an N-methylpyrrolidone (NMP)/water solvent mixture. The insertion and synergy of TCB and NMP widen the lattice and expand crystal particles, promoting Zn2+ ion transfer and coordination, which endow s-NMP-TCB-V2O5 with an improved capacity of 452 mA h g-1 as well as outstanding capacity retention of 85.6% after 1500 cycles.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
