“Even most electric vehicles have a lead-acid battery, in order to power the car’s electronics,” he adds. It’s not all doom and gloom, however. Mão de Ferro and his team have been working on ways to mitigate the use of lead-acid batteries in heavy commercial vehicles, in part through the EU-funded HYCAP project.
In addition, lead batteries are easy to recycle, making them economical. Once smelted down, they can be shaped into lingots and shipped back to the manufacturers. “Lead-acid batteries are cheap,” says Mão de Ferro. “Potential alternatives such as nickel cadmium are also toxic, and are banned for use in cars because of safety concerns.”
The key reason is that lead batteries pack a punch: viable, cost-effective, safe and scalable alternatives capable of delivering the necessary power have yet to be fully developed. In addition, lead batteries are easy to recycle, making them economical. Once smelted down, they can be shaped into lingots and shipped back to the manufacturers.
“Potential alternatives such as nickel cadmium are also toxic, and are banned for use in cars because of safety concerns.” This lack of a viable alternative is why lead has not been banned from automotive applications. “Even most electric vehicles have a lead-acid battery, in order to power the car’s electronics,” he adds.
Lithium-ion batteries have a high power-to-weight ratio, high energy efficiency, and good high-temperature performance. In practice, this means that the batteries hold a lot of energy for their weight, which is vital for electric cars – less weight means the car can travel further on a single charge.
Four main kinds of batteries are used in electric cars: lithium-ion, nickel-metal hydride, lead-acid, and ultracapacitors. Lithium-ion batteries are the most common type of battery used in electric cars. This kind of battery may sound familiar – these batteries are also used in most portable electronics, including cell phones and computers.
