New Battery Tech For Electric Cars Extends Its Range

Electric cars and the form of similar transport are fast becoming popular. Instead of being a niche market, it is slowly going more and more mainstream. The demand for electric transport is increasing just as the market costs involved into owning one are going down. Additional developments in the technology may even make it compete better with gasoline cars in the future. One example where it may have the edge in the near future is the doubling of the range it can go, thanks to new battery technology.

Researchers from the Korea Institute of Science and Technology have reported of developing a new carbon-silicone material that can potentially double the driving range of electric vehicles. Not only that, researchers say batteries made out of the said material can also charge to more than 80 percent capacity in just as little as five minutes. This will certainly vastly improve the efficiency of electric vehicles in terms of driving distance.

The researchers made use of silicon anodes, which can hold ten times the capacity over the often used graphite anodes. But the problem with silicone anodes is that they are very bad at holding that capacity over time.

The team, who was led by Hyun-Gi Jung, found a way to keep the silicone anodes more stable. They made use of a simple thermal process that is also commonly used for frying food. This process involves using oil, water, and starch. The process allowed the silicone anode batteries to have four times the capacity of current graphite anode batteries. The new batteries also remained stable for over 500 cycles. Because of carbon present in the silicone anode, it did not expand, which is a common problem involving the use of silicone in battery tech.

Jung said, “We were able to develop carbon-silicon composite materials using common, everyday materials and simple mixing and thermal processes with no reactors.” He further added that it has a high potential for the new battery type to be commercialized and mass-produced.
