Spanish graphene batteries to power electric cars


The Spanish companies Graphenano and Grabat Energy, in conjunction with the Universidad de Córdoba, have developed polymer-graphene batteries that allow electric cars to travel 1,000 kilometers before they need to be recharged.

Graphenano, a Spanish industrial-scale manufacturer of graphene, has joined forces with the Universidad de Córdoba in order to develop the first polymer-graphene batteries. The company Grabat Energy will produce the battery cells starting next year. This new technology incorporates the use of polymer-graphene.

The new product, developed in collaboration with the Universidad de Córdoba, has more capacity than any other technology currently available on the market and therefore minimizes the amount of energy that is lost during usage. Graphene batteries offer triple the capacity of the best technology that now exists. What’s more, these batteries last up to four times longer than traditional nickel-metal hydride batteries and twice as long as lithium batteries. Using graphene also cuts the weight of the batteries in half compared to conventional batteries, improving their performance and the autonomy of the equipment using them.

The Universidad de Córdoba is now working to reduce the batteries’ size, given that their high density limits use to electric vehicles such as cars or boats. In the future it’s expected they will become small enough to fit into electronic devices such as cellphones.

Another advantage of the graphene batteries that will be manufactured and sold by Grabat Energy is their cost. They are expected to be up to 77% cheaper than lithium batteries, as well as compatible with existing devices and vehicles. Thus it won’t be necessary to adapt any infrastructure for their use which favors rapid implementation.

Prototypes using this technology have already been successfully manufactured in Córdoba. Grabat Energy expects to begin operating the first polymer-graphene cell manufacturing plant in Spain during the first half of 2015. In the meantime, two of Germany’s four largest automobile manufacturers will receive samples of the product in order to test it in their vehicles and accelerate implementation.
