Research into batteries will give electric cars the same range as petrol cars
i-air batteries are a promising opportunity for electric cars. "If we succeed in developing this technology, we are facing the ultimate breakthrough for electric cars, because in practice, the energy density of Li-air batteries will be comparable to that of petrol and diesel, if you take into account that a combustion engine only has an efficiency of around 30 percent," says Tejs Vegge, senior scientist in the Materials Research Division at Risø DTU.
If batteries with an energy density this great become a reality, one could easily imagine electrically powered trucks. The electric car was introduced by Edison as early as 1900. But, as we all know, Henry Ford's vehicle concept with a noisy, smelly combustion engine won the race to become people's most treasured individual means of transport, despite the fact that in principle, the combustion engine is hopeless.
