High-performance symmetric electrochemical capacitor based on graphene foam and nanostructured manganese oxide

Bello, A.; Fashedemi, O. O.; Lekitima, J. N. et al (AIP Publishing, 2013)

We have fabricated a symmetric electrochemical capacitor with high energy and power densities based on a composite of graphene foam (GF) with ?80 wt% of manganese oxide (MnO2) deposited by hydrothermal synthesis. Raman ...
Microwave assisted synthesis of MnO2 on nickel foam-graphene for electrochemical capacitor

Bello, A.; Fashedemi, O. O.; Lekitima, J. N. et al (Elsevier, 2013)

A green chemistry approach (hydrothermal microwave irradiation) has been used to deposit manganese oxide on nickel foam-graphene. The 3D graphene was synthesized using nickel foam template by chemical vapor deposition (CVD) ...
