Researchers studied lithium ion battery behavior at nanoscale23 September 2010
Lithium ion batteries are used for a number of applications and consumers need improved battery life and researcher team lead by Nina Balke, Stephen Jesse and Sergei Kalinin at Department of Energyâ€™s Oak Ridge National Laboratory are examining the functioning of the lithium-ion batteries. Researchers developed scanning probe microscopy also called as electrochemical strain microscopy (ESM) for examining the lithium ion movement.Â
The current technique developed by the researchers is design to measure strain and subsequently the motion of lithium ion at nanoscale, however the conventional electrochemical technique analyze electric current, which is too small to measure at nanoscale and therefore the current technique is suitable to reveal the battery behavior.Â
Lithium-ion batteries are now a days most common for various applications including cell phones to electric vehicles and being light weight and having high energy density and re-chargeability, scientists are working towards extending the life of these batteries. Before proceeding towards the extended life, researchers are trying to understand the functionality of the battery at nanoscale that makes one battery long life and another fail after a short duration.Â
The research team includes Balke, Jesse and Kalinin from ORNLâ€™s Nanophase Material science Centre and Nancy Dudney, Yoongu Kim and Leslie Adamczyk from ORNLâ€™s Material Science and Technology Division and Anna Morozoyska and Eugene Elisee from National Academy of Science, Ukraine and Edwin Garcia and Tony Chung from Purdue University. The research findings has been published in the journal â€œNature Nanotechnologyâ€.
