Scientists were able to increase the capacity by 3000%.
Researchers have developed an ultramicro supercapacitor that surpasses existing models in terms of storage and compactness. Its design includes field-effect transistors and layers of molybdenum disulfide and graphene, resulting in an impressive 3,000% increase in capacitance under certain conditions.
This tiny device is capable of storing a huge amount of electrical charge. It is also much smaller and more compact than existing supercapacitors and has the potential to be used in many devices, from street lighting to consumer electronics, electric vehicles and medical devices.
Supercapacitors combine the best qualities of batteries and capacitors: they can store and release large amounts of energy, making them highly sought-after for next-generation electronic devices.
In a recent study published in ACS Energy Letters, scientists used field-effect transistors as charge collectors instead of the metal electrodes used in existing capacitors. Current capacitors typically use metal oxide-based electrodes, but these are limited by poor electron mobility. Therefore, the researchers decided to create hybrid field-effect transistors consisting of alternating layers of molybdenum disulfide (MoS2) and graphene.
In the future, the researchers plan to explore the possibility of replacing MoS2 with other materials to further increase the capacity of their supercapacitor. They also plan to apply for a patent for a supercapacitor.
