Electric cars have come a long way over last couple of years thanks to the automobile manufacturers’ increased interest in the sector. While the electric cars offer greater travel distances at the moment, charging the electric cars is still a major concern for consumers. This is largely because of the required time to charge up electric vehicles compared to the process of filling up at a gas station. However, researchers at the Penn State University have revealed a new technology that could solve the problem significantly as the new technology could recharge an electric car’s battery up to 80 percent in just 10 minutes.
Led by Chao Yang Wang, the researchers from the university started out playing with the technology with pretty simple concept of just recharging a lithium-ion battery with as much energy as possible. However, supercharging a lithium-ion battery in such manner has its own shortcomings as there is a change for to form plate-like deposits on the negative electrode’s surface to decrease battery life.
Interestingly, the group of researchers came up with the idea to heat up the battery to a high temperature first. This would prevent lithium plates to form in the electrode’s surface. Afterwards, the group tested the method out on available commercial batteries. At first, they tested the battery without heating it first to find out that the lithium plates began to form just after 60 cycles.
However, after heating up the battery to 60C, the researchers managed to recharge the battery 2,500 times without lithium plates form. According to the researchers, the amount of cycles translates to 750,000 kilometers.
Although we will have to wait to find out if the technology finds its way to electric car batteries going forward, the researchers are hoping to reduce the recharging time to as low as 5 minutes.
