Pheneovate works with public and private laboratories around the world to prototype graphene batteries, supercapacitors, and battery components designed to your exact application specifications. This overview focuses specifically on graphene's application for battery technology.
Graphene has recently enabled the dramatic improvement of portable electronics and electric vehicles by providing better means for storing electricity. Graphene has proven useful for several different types of batteries, with lithium-ion batteries being most important to our team and our partners. Li-ion batteries can be enhanced by introducing graphene to the battery’s anode and capitalizing on the material’s conductivity and large surface area traits to achieve morphological optimization and performance.
Since graphene can be chemically processed into various forms suitable for both the positive and negative electrodes, this enables the fabrication of all-graphene batteries with ultrahigh energy density.
Advantages of Graphene Batteries
Higher Capacity
Fast Charging
Flexibility
Lightweight
High Temperature Range
Conventional (and prospective) battery electrode materials are significantly improved when enhanced with graphene. A graphene battery is lightweight, durable, and suitable for high capacity energy storage, as well as shortened charge time. Graphene adds conductivity without requiring the amounts of carbon used in conventional batteries.
Graphene has the potential to enable high energy density supercapacitors that are smaller, lighter, and faster than current products on the market.
