Quote: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.Battery breakthrough quintuples electric vehicle range | The Independent
Quote:Samsung and IBM had claimed that their new semiconductor chip design could give smartphones a week-long battery life. The new Vertical Transport Field Effect Transistors (VTFET) design will not yet be used in consumer chips, but the companies claim that they could offer “two times improvement in performance or an 85 percent reduction in energy use” compared to current designs. This is because, for chip manufacturers, Moore’s Law remains a tough challenge. The law states that the number of transistors in a chip doubles every two years, and makers are quickly running out of space. Transistors generally lie flat on the surface of the chip with the current flowering laterally, but with this new design the transistors can be arranged vertically – so electricity can flow up and down.Phone batteries could last a week with new chip, IBM and Samsung says | The Independent
Quote:Companies are waiting as long as 60 weeks for chips they had ordered to arrive – and it is not expected to get better soon. In October, Intel said it was in the “worst” of a crisis that will not be alleviated until 2023. “We’re in the worst of it now, every quarter next year we’ll get incrementally better, but they’re not going to have supply-demand balance until 2023,” chief executive Pat Gelsinger said.Phone batteries could last a week with new chip, IBM and Samsung says | The Independent
