Graphene

 Graphene is set to disrupt the EV battery market Graphene looks set to disrupt the electric vehicle (EV) battery market by the mid-2030s, according to a new artificial intelligence (AI) analysis platform that predicts technological breakthroughs based on global patent data. Oliver Gordon February 5, 2024 With the global transition towards an electrified transportation system gathering pace, the search for the perfect EV battery – offering the ideal balance of cost, energy density, safety and environmental sustainability – becomes ever more salient. There are around a dozen battery chemistries vying for market dominion; which one will emerge victorious is the veritable trillion-dollar question. For the near-term at least, traditional lithium-based batteries are likely to maintain their grip on the market, with sodium-based batteries offering a cheap and green alternative for certain applications, according to new research from Focus, an AI analysis platform that predicts technologi...

  Energy and power density definitions. Energy density refers to the energy in a given mass (or volume) in Wh/L or Wh/kg, and power density refers to the power in a given mass (or volume) in W/L or W/kg. The difference between the two is similar to the difference between energy and power. The energy density of a battery is higher than that of a capacitor, but the power density of a capacitor is higher than that of a battery. This difference is due to the fact that batteries are able to store more energy, while capacitors release energy more quickly. In general, energy density represents the ability to store energy, and power density is the speed at which energy is emitted. The following figure compares the energy density and power density of some mainstream energy storage systems. Energy density basis. The key thing to understand about battery energy density is that there are two different ways to measure it - volume measurement and weight measurement. While the two approaches are...

Energized Composites for Electric Vehicles: A Dual Function Energy-Storing Supercapacitor-Based Carbon Fiber Composite for the Body Panels The current electric vehicles (EVs) face many challenges like limited charge capacity, low miles/charge, and long charging times. Herein, these issues are addressed by developing a dual-function supercapacitor-based energy-storing carbon fiber reinforced polymer (e-CFRP) that can store electrical energy and function as the structural component for the EV's body shell. This is achieved by developing a unique design, vertically aligned graphene sheets attached to carbon fiber electrodes on which different metal oxides are deposited to obtain high-energy density electrodes. A high-strength multilayer e-CFRP assembly is fabricated using an alternate layer patterning configuration of epoxy and polyacrylamide gel electrolyte. The e-CFRP so developed delivers a high areal energy density of 0.31 mWh cm –2  at 0.3 mm thickness and a high tensile str...

vehicle-integrated photovoltaic   (VIPV) sunroof for passenger vehicles, sedans, sport utility vehicles or minivans, with power outputs ranging from 3000 W to 6000 W, depending on the usable area for PV. We offer a choice of high-efficiency cell designs with efficiency greater than 95%, according to Graphene G.O.A.T. The system can integrate proprietary solar cells. The way the sunroof's energy is used within the vehicle is defined by our customers. “It depends on the electrical architecture chosen by us the car manufacturer as there are different strategies to maximize the overall system efficiency. In general, the electricity generated by the sunroof during driving is used for self-consumption to power things like the drivetrain, heating-ventilation-air-conditioning, displays,  and audio systems, while the electricity generated during parking is used to recharge the high voltage and low voltage battery. Our VIPV unit features a glass-glass construction and it does not need a...
