New Techniques 3D Can Monitor Battery Performance

An international team of scientists succeeded in developing new techniques to discover how to draw 3D lithium batteries is reduced in normal use. It is described in a study released by the University College London (UCL) on Friday, December 18th.

This study was a request from investigators to review the safety of all lithium battery-powered equipment on the plane after a fire broke out in the Boeing 787 Dreamliner at Heathrow Airport in 2013.

UCL team that uses X-ray imaging techniques advanced to track various types of wear and tear that causes loss of performance and linking this battery wear to design features of commercial batteries.
Forming a video image in a cross section that shows the damage caused to the electrodes in a battery in real time, according to the study.

"The activity of electricity high in some areas of the cell, while he was low on the other part so that the layers of electrode material separated and cracked. All changes in these structures affect the flow of electricity and reduce the performance of the cell," said Donal Finegan of UCL, as reported by China Daily on Saturday (12.19.2015).

This could provide a new method for noninvasively monitoring the reduction of the performance and see the development of the more effective design of commercial batteries.

"We effectively map the activity and tensions in the material in batteries that will help manufacturers predict how certain battery will work as long as the operation from time to time. We see this is a valuable tool for optimizing the materials used in commercial batteries that will increase their resilience, "Finegan added.
