Electric vehicles are on track to become the predominant mode of transportation in the very near future. According to The Global EV Outlook 2020, the total number of electric cars worldwide has already surpassed the 7 million mark. With global car manufacturers investing heavily in electric vehicle production, the number of EVs is set to expand exponentially over the next decade.
Leading the charge in battery technology is the tried and true lithium-ion battery, the industry standard among battery technologists. Lithium-ion batteries offer several advantages over their predecessors, such as lighter weight, longer life, and higher energy density.
Perhaps the biggest advantage of lithium-ion batteries is their capability to store more energy in a smaller package. This means that less batteries are needed to power a vehicle, which in turn translates to more range and improved efficiency.
The battle to extend the range of electric cars also involves the development of new battery technologies. The research and development team at Tesla are pushing forward with their cutting-edge battery technology, while scientists at major universities continue to search for an alternative to lithium-ion batteries.
One such alternative is the solid-state battery. Solid-state batteries are designed to last longer and use fewer materials than lithium-ion batteries, thus making them more cost-effective. Furthermore, solid-state batteries are also more stable and less prone to catching fire than lithium-ion batteries.
Another groundbreaking alternative is the supercapacitor. Supercapacitors offer fast charging and discharging speeds, making them ideal for electric car use. They are also highly efficient, with the potential to store up to 10 times more energy than lithium-ion batteries and have a lifespan of up to one million charge cycles.
Innovative battery technology is undoubtedly playing a major role in the electric car revolution. As technologies continue to evolve, electric vehicles will become both more affordable and efficient over time, paving the way for a clean, green future.
