Graphene batteries are starting to be integrated into next-generation electronics and vehicles. For example this Lamborghini concept uses the car body itself as part of the battery.
“Thinking about mission-critical technologies, as I pen this piece my iPhone’s battery is blinking red. So many unmanned systems are dependent today on lithium-ion batteries from robots to drones to autonomous vehicles. This is driving an enormous demand to mine more of the mineral, which negatively impacts the environment and depletes natural resources.”…
In addition to the conservationist argument, lithium-ion is inefficient. As an example, recharging one’s Tesla at their supercharging station takes 40 minutes, compared to five minutes at the pump for a combustion engine.
However, today we are on the cusp of major discoveries that promise to save the planet. Starting back in 2004, at the University of Manchester, a breakthrough new energy source was found inside the common pencil. …
Unlike atoms in a liquid, which move in random directions, atoms connected in a sheet of graphene move together. This means their energy can be collected using existing nanotechnology.” Thibado’s technology is micro-small as the graphene demonstrated only measures 10 microns across, enabling 20,000 pieces of graphene to fit on the head of a pin (hence, less mining).
This means a tiny graphene membrane could power an Apple watch forever, without ever being charged. Thibado calls his technology the “Vibration Energy Harvester” a self-charging power source for the future. The professor is aiming to take his innovation to the healthcare space as “Self-powering enables smart bio-implants, which would profoundly impact society.”
While still early in its development, graphene batteries are starting to be integrated into next-generation electronics and vehicles. Recently, Chinese manufacturer Dongxu Optoelectronics unveiled its “graphene supercapacitor” that is the size of a laptop battery that transforms hours of charging time into minutes. Spanish startup Earthdas plans to market later this year its own battery for e-bikes and motorcycles boasting of a 12x faster charging time than current lithium-ion batteries.
One of the most exciting use cases for this innovation is incorporating graphene into the bodies of automobiles. A French company, Nawa Technologies, is already working on developing flexible polymers or coatings that are built directly into a vehicle’s chassis. As the company’s CEO, Ulrik Grape, boasts, “In a way, it will be like having a battery-free car.” Further validating Grape’s statement, Lamborghini partnered with the Massachusetts Institute of Technology to develop a graphene-enhanced supercapacitor built directly into its car body….”

“By incorporating research from Dinca and John Hart, associate professor of mechanical engineering, who will investigate new carbon fiber and composite materials that could enable the complete body of the car to somehow be used as a battery system, the hope is that this ambitious, visually stunning prototype will become a reality.”
