The synergistic effect of the RuO 2 nanoparticle-decorated V 2 O 5 heterostructure for high-performance asymmetric supercapacitors
Two-dimensional RuO 2 nanoparticle-decorated V 2 O 5 nanoflakes are successfully synthesized by a simple solvothermal method. The synthesized RuO 2 -decorated V 2 O 5 nanocomposite electrode exhibited a high charge–discharge capacity with an excellent cyclic retention of 94.6% over 10 000 cycles. Sp...
