The Spanish company Graphenano has introduced a graphene polymer battery that could allow electric vehicles to have a maximum range of a staggering 800 kilometers (497 miles). The battery can also be charged in just a few minutes.

The company notes that the battery is designed for a number of uses, and could be put in houses, bicycles, drones, and even pacemakers. Dubbed Grabat, the batteries will be manufactured in Yecla, Spain and will have an energy density of 1,000 Wh/kg (for comparison, lithium batteries generally have a energy density of 180 Wh/kg). Grabat will also have a voltage of 2.3 V.

If thatís not enough, the battery could discharge and charge faster than a standard lithium ion battery (almost 33 times that of lithium). It also does not exhibit memory effect, a phenomenon in which charging a battery multiple times lowers its maximum energy potential.

Best of all, independent analyses by T‹V and Dekra have demonstrated that the batteries are safe and are not prone to explosions like lithium batteries, and tests conducted by the company have shown that, after being short-circuited, the battery is able to return to work with 60% of the load.
what will they cost to produce, whats the typical life span of them ?, whats the overall environment impact , ie from harvesting materials to produce all the way to disposal .
i suppose in reality the main decider here is going to boil down to the total environmental impact and the cost per mile and longevity of these batteries .
