文摘

Nafion membranes were modified via sol-gel condensation of aminosilane. The effect of aminosilane loading on the membrane properties is studied. High loadings of aminosilane result in strong anisotropy of membranes. An optimum aminosilane loading is found. Vanadium redox batteries with composite membranes have improved energy efficiency.
