Electric car batteries: myths and realities

Electric car batteries are often at the center of debates. Made from non-ecological, non-recyclable materials, expensive to replace, short lifespan... These are preconceived ideas that we often hear about...

What is the reality? Are they myths or realities? In this article, BEQ Technology addresses the most frequently heard myths about electric car batteries.

MYTH #1: AN ELECTRIC CAR BATTERY IS NOT RECYCLABLE

This oft-repeated myth is false. Nowadays, we recycle 95% of the materials used in the battery. In fact, Recyclage Lithion, a Montreal-based company, has developed an innovative technology that recycles 95% of the components of lithium-ion batteries.

Furthermore, when the batteries in an electric vehicle using lithium-ion are deemed too worn for driving, they still have up to 80% of their charge. Before being recycled, these batteries are reused to support the grid, particularly alongside energy sources that may not be as stable, such as wind or solar power. The batteries can store energy to continue providing electricity if the wind or sun is not available.

MYTH #2: YOU NEED TO CHANGE THE BATTERY OF AN ELECTRIC CAR AFTER TWO OR THREE YEARS.

Here is another widespread false belief. The batteries of hybrid and electric cars last as long as the car itself, or even longer. Specifically, the batteries have a warranty of 8 to 10 years (or 160,000 km) according to manufacturers. After driving about 150,000 to 200,000 km or for 10 to 15 years, they retain about 80% of their initial capacity!

MYTH #3: THERE ARE NOT ENOUGH RESOURCES TO BUILD BATTERIES FOR ELECTRIC CARS.

In the manufacturing of batteries, several minerals such as lithium, cobalt, nickel, and copper are used. Is there a risk of a shortage as some fear? In fact, the risks are low since researchers at MIT have shown that the supply of lithium will not be a problem for the next 15 years. As for cobalt, it may no longer be as essential with the arrival of batteries that do not require it in the short term. Regarding copper and nickel, mines already produce them in large quantities since they are abundant in the ground. In the coming years, it is certain that new technologies will develop, so the risk of a shortage is very low.
