Graphene Super Battery-Future Of Electric Vehicle
EVs promise a cleaner tomorrow—but battery limits hold them back. Enter graphene: the wonder material giving batteries speed, power, and endurance. Discover how this tiny innovation could supercharge the world’s shift away from fossil fuels.
Electric vehicles are emerging as a cleaner alternative to conventional vehicles powered by fossil fuels, but issues like longer battery charging time have hampered the widespread adoption of these new alternatives.
Over the decades, battery makers embraced lithium over silicon because it has a high electrical capacity. But lithium has two key problems:
- Poor Electrical Conductivity
- Gets physically deformed during discharges
Coating the Lithium Silicon Anode with nanomaterial like graphene solves both these issues.
Properties of Graphene
Graphene is highly conductive, allows electricity to flow, and is rigid. So, it helps the lithium keep its shape and prevent dendritic creep, allowing the battery to last longer and have a longer lifecycle.
Graphene has very high electrical conductivity, so the conductivity goes up when you put it in a silicon anode. And graphene has really good mechanical properties, so it doesn’t allow the silicon anode to expand that much, so it will not break.
In the last 15 to 20 years, the whole energy storage community has been doing a lot of work on how to make a good nanocomposite material, and this silicon graphene anode has the desired properties.
