Batteries have been important to providing power to mobile devices for decades. From the early transistor radios and automobiles, through to today’s smartphones and electric cars, many advances in technology have been enabled by advances in battery technology.
Batteries enable electricity to be stored and made available when the device is not plugged into a power source, or when the power is needed to be stored and used at a later time. In today’s technological world, we need batteries to be smaller and lighter, to last longer and store more energy, to be made of less toxic or volatile substances, and to be cheaper and easier to produce. We also need increasingly complex battery systems if we are to harness the power of renewable energy, as the sun, wind or waves do not supply a constant flow of energy.
Traditional batteries use electrochemical cells to convert stored chemical energy into electrical energy. Disposable batteries are produced from Zinc-Carbon or Alkaline, while reusable batteries rely upon Nickel-Cadmium or Lithium Ion Polymer.
Graphene has the potential to radically increase the efficiency of Lithium Ion batteries. They will last longer, hold more charge and can be charged more quickly, which also means they will be smaller, lighter and possibly flexible. Current research is looking at ways to combine graphene with lithium to solve many of the challenges consumers around the world face on a daily basis.
However the advances in technology fueled by graphene are not limited to having to charge ones smartphones less frequently. One of the main drivers in battery technology is fueling high demand products such as automobiles, planes and houses, and storing energy from renewable sources such as solar, wind or tidal power. In these spheres, combining graphene with lithium is likely to change the energy industry radically.
Together with solar power, batteries are key to the shift away from fossil fuels towards a world powered by renewable energy. Storage and mobility of electricity will be essential to the success of this transition, and graphene looks set to play enabling role in its rapid growth.
