It is the main topic of my applied research: Graphene super battery
In order to use periodically renewable energy sources such as wind and solar energy as a reliable source of energy, we must have an efficient energy storage system. How can we apply emerging technologies to develop energy storage and renewable energy sources and make the world more sustainable?

Graphene-based batteries hold exciting possibilities, research and development are intensive.
The application of graphene in this field offers new possibilities in the field of energy storage, with high charging and discharging rates and even economic affordability. Graphene-enhanced performance thereby blurs the traditional distinction between supercapacitors and batteries.
Advantages of graphene batteries: Greater capacity - Faster sharing- Flexibility- High temperature range
In the field of batteries, conventional battery electrode materials (and prospective ones) are significantly improved when enhanced with graphene. A graphene battery can be light, durable and suitable for high capacity energy storage, as well as shorten charging times. It will extend the batteryâs life, which is negatively linked to the amount of carbon that is coated on the material or added to electrodes to achieve conductivity, and graphene adds conductivity without requiring the amounts of carbon that are used in conventional batteries.
Graphene Batteries can reduce the environmental impact of battery use.

Graphene-based Litium-Ion batteries are an emerging technology.
Battery and graphene technology startup Nanotech Energy closed a $27.5 million funding round in 2020 at a trailing valuation of $227.5 million. The startup uses a solution processing method that allows graphene to be coated on “any substrate” along with a laser process step that forms a graphene foam. The company had originally applied its graphene technology to making better supercapacitors, but now focuses on its “super battery.”
The company announced it would supply more than 1 GWh of battery energy storage systems (BESS) to Athens-headquartered Smile Energy, acting as the distributor for Greece and the surrounding region with Nanotech Energy BESS products through to 2028. Greece has recently doubled its 2030 energy storage target to 3 GW. “Nanotech Energy is the first and only producer to break the 50% content barrier by reaching 98% monolayer graphene, the wonder material that powers our products. We've already developed groundbreaking energy storage using technology that has the high capacity of a battery and the power performance of supercapacitors in a single solution,”
