South Korean Hyundai Motor Company, its sub-brand Kia and Factorial Energy are jointly developing and will soon offer new batteries for electric vehicles. The project is based on developments in Factorial Energy's solid electrolyte batteries. Initial tests have shown that these power cells increase the range of an electric vehicle by 20-50%. In addition, they cannot catch fire and their mass production does not require modifications to existing assembly lines.
Factorial Energy's main achievement is Factorial Electrolyte System Technology (FEST). This is the company's patented solid electrolyte, which ensures the absolutely safe operation of high-voltage battery cells with high capacity. The new patented system is now adapted to relatively small energy cells with a capacity of 40 amp-hours operating at room temperature. Larger prototypes are being prepared and will also undergo extensive testing.
According to the developers, FEST has three main advantages over traditional lithium-ion batteries. Firstly, the technology is much safer as there is no spontaneous combustion or ignition even if the casing is obviously destroyed. Secondly, it provides a higher energy density, which increases the range of electric vehicles by 50%. In addition, FEST-based battery production can be directly integrated into existing assembly lines without the additional cost of factory refurbishment.
