Scientists have developed a biologically-inspired membrane that could quintuple the charge capacity of electric car batteries, thereby massively increasing their range.
A team from the University of Michigan used recycled Kevlar – the same material found in bullet-proof vests – to create a network of nanofibres similar to a cell membrane. They then used this to fix fundamental issues with a next-generation battery type, known as lithium-sulfur.
Until now, this type of battery’s cycle life – the number of times it can be charged and discharged – has been insufficient for commercial use in electric vehicles, despite their capacity benefits.
