In this Account, I summarize some of our new ideas and strategies for the controlled functionalization of graphene for the development of efficient energy conversion and storage devices, such as solar cells, fuel cells, supercapacitors, and batteries.
Graphene-based batteries represent a revolutionary leap forward, addressing many of the shortcomings of lithium-ion batteries. These batteries conduct electricity much faster than conventional battery materials, offer a higher energy density, and charge faster because of Graphene.
In 2018, more than 25% of lithium battery publications were related to graphene. Using graphene has benefits in advancing battery material performance. In industry, the mainstream applications of lithium-ion batteries gradually shifted from cell phones and portable consumer electronics to transportation and grid storage applications.
Emerging consumer electronics and electric vehicle technologies require advanced battery systems to enhance their portability and driving range, respectively. Therefore, graphene seems to be a great candidate material for application in high-energy-density/high-power-density batteries.
Unfortunately, conventional energy generators are not capable of responding to environmental changes, while traditional energy storage devices lack special functionalities apart from supplying electricity. Benefiting from exceptional physicochemical properties, graphene-based materials help to address the aforementioned issues.
Currently, applications of graphene focus mainly on the storage and conversion of electric and light energy to provide alternative energy sources to replace fossil fuels [5, 6] with typical representatives being supercapacitors and lithium batteries [7, 8, 9, 10], as well as photocatalysis applications to provide eco-friendly devices [11, 12].
