Graphene Application in New Engergy

As the global population grows, the demand for energy production and storage continues to increase. Graphene and related materials (GRMs), with their high surface area, large electrical conductivity, lightweight properties, chemical stability, and high mechanical flexibility, play a key role in meeting this demand in energy production and storage.
One of the areas of research that is being highly studied is energy storage. While all areas of electronics have been developing at a very rapid rate over the past few decades (referring to Moore's Law, the number of transistors used in electronic circuits doubles every 2 years), the problem has always been that storing energy without using in batteries and capacitors. The development of these energy storage solutions has been much slower. The problem is this: a battery might store a lot of energy, but it might take a long time to charge, capacitors on the other hand can charge quickly, but can't store that much energy (relatively speaking). The solution is to develop energy storage components, such as supercapacitors or batteries, that can provide both positive properties without compromise.

Currently, scientists are working to improve the capabilities of lithium-ion batteries (by using graphene as the anode) to provide higher storage capacity, better lifespan and charge rate. In addition, graphene is being researched and developed for use in making supercapacitors that can charge very quickly, while also being able to store large amounts of electricity. Graphene-based micro-supercapacitors may be developed for low-energy applications such as smartphones and portable computing devices, and may be commercialized within the next 5-10 years. Graphene-enhanced lithium-ion batteries could be used in higher energy-consuming applications, such as electric vehicles, or they could be used in smartphones, laptops, and tablets like today's lithium-ion batteries, but at a much lower size and weight.
