Graphene for batteries, supercapacitors and other energy storage

20 июля, 2017 - 12:19
Graphene currently is the most studied material on the planet - this is especially true for charge storage and the results from many laboratories confirm its potential to change today's energy-storage landscape. Specifically, graphene could present several new features for energy-storage devices, such as smaller capacitors, completely flexible and even rollable energy-storage devices, transparent batteries, and high-capacity and fast-charging devices.

Three-dimensional nanosheet electrodes for efficient electrochemical and photoelectrochemical water splitting

20 июля, 2017 - 10:21
Developing highly active electrocatalysts for photoelectrochemical water splitting is critical to bringing solar/electrical-to-hydrogen energy conversion processes into reality. Researchers have developed a novel 3D hierarchical hybrid electrocatalyst grown on electrochemically exfoliated graphene. The researchers then further integrated the hybrid nanosheets with a macroporous silicon photocathode, and the results show that it can enable highly active solar-driven photoelectrochemical water splitting in both basic media and real river water.
