The cause of fire blight study in Cambridge identified


ABSTRACT:Scientists have identified a reason why the lithium laptop batteries in laptops and mobile phones could overheat and catch fire.

Researchers at the University of Cambridge said the growth of metal fibers, called dendrites, could cause short circuits.Nuclear Magnetic Resonance (NMR), normally used to identify elements in molecules, has adapted to "see" how to develop dendrites.The researchers said it could help resolve fire safety issues that have been carried out the development of lithium Dell Latitude D800 Battery. The lithium Pavilion dv8000 Battery technology is said to be crucial for progress in the next generation of electric cars.

Fast Reheat

When the laptop batteries are charged quickly lithium dendrites current minutes can form in carbon anodes. These fibers can cause a short circuit, causing the Asus Eee PC 1000H battery to overheat and catch fire quickly, Angel Gray Professor, Department of Chemistry, University of Cambridge, said. "These deaths lithium fibers were a significant barrier to the marketing of the new generation of higher capacity batteries," he said.

The fire safety must be resolved before reaching the next generation of lithium ion laptop batteries and before they can safely use these batteries in a wide range of transport applications. Now that we can control the formation of dendrites inside the IBM laptop batteries can be identified when formed and under what conditions. "Our new method should allow researchers to identify what conditions lead to the formation of dendrites and quickly screen possible solutions to avoid the problem."
